Perspective on Infant Baptism
As someone who has been brought up in his faith within an Anabaptist type movement I've not been in favor of infant baptism for several years. My approach to the issue has always been summed up in the words "It can't hurt." I acknowledge that scripture does not directly address the issue and how one ought to approach it. However, my opinion may be changing. I may be starting to like the idea and I now see that scripture may not answer the question of "should we baptize infants" but it does give us indications of how the kingdom of God exists and operates and gives an idea of how early believers may have practiced baptism.Baptism is the outward expression of one's faith in Jesus Christ as Lord and it is also the ritual performed by both a community and individual in order to accept a person into the community/Body/Bride of Christ. It is as much a personal action as it is a community ritual. The baptism of an individual has just as much importance for the entire faith community as it does for the individual in the sense that both are changed in identity by the sacrament. To seek baptism is to choose to enter into a community identified by and united with Jesus Christ. For the Church to baptize someone is for that community to accept them as Christ has into his fold and commit themselves to this new member of Christ's body. It is like a hand accepting a pinky it was lacking. Much more could be said about the beautiful sacrament of baptism (and believe that I would talk about its goodness all day if it were beneficial and desired by readers) but for our purposes here this will suffice for an explanation of the nature and affect of baptism.
I have not been in favor of infant baptism for the same reason as many Anabaptists; an infant does not possess the experiences, education, or mentally capacity necessary to make the type of decision that precedes and necessitates the sacrament of baptism. An infant can not understand the sacrament and thus is forcefully brought into a community is did not desire to enter into. The argument here is that only an adult who is familiar with his/her own sin, Christ, and the Church could commit to such a ritual.
The arguments that have been challenging my position accept the same truths. However, the perspective is different. The position above seems to accept the importance of baptism for the individual but not the community. First, on the other side, while the infant may not be able to make the choice, the community and parents surrounding the infant have choices to make. They must decide how they will love and accept the infant. Will the community accept the child into itself or will they look upon the infant as an alien as it grows in their midst? To baptize the infant is an act not of force but love. It is a commitment made by the parents and community to love the child and raise it as a member of the body of Christ. What parent does not want to raise their child in the way that it should go (Proverbs 22:6)?
Second, baptism is likened to circumcision in the Old Testament. Yahweh commanded his people to be circumcised (a discipline focused only on males) so that they may be marked as a unique society within creation. In the New Testament circumcision is abolished as a marking of God's people and baptism becomes the new ritual (and to step on an egalitarian soapbox, it is for both male and females, exampling progress in the revelation of God's kingdom and the equality that exists in it). When children were born into the Israel community they were circumcised. They had no choice (a hot button issue these days) but as infants today would not have a choice in their baptism. This does not seem to trouble God though. In fact, he commands it be done for he wants all new additions to his society to be marked for in His name. This includes both infants and converts. The New Testament gives examples of entire families coming to faith and being baptized together (Acts 16:15, 33; 1 Corinthians 1:16). Many supporters of infant baptism believe this to include children below the age of accountability, including infants.
This practice is one of the oldest in Christian history. Why would this change today? What reason do we have to believe God no longer desires for new additions of his unique and divine society to be marked in his name be they converts or infants? We know it is commanded for converts and that it is the New Covenant equivalent to circumcision so it only makes sense that infant baptism should be practiced. Ulrich Zwingli (1484-1531), a church reformer, once wrote of infant baptism,
The sacraments are given as a public testimony of that grace which is previously present to every individual. This baptism is administered in the presence of the Church to one who before receiving it either confessed the religion of Christ, or has the word of promise whereby he is known to belong to the Church. Hence, it is that when we baptise an adult we ask him whether he believes. If he answer, Yea, that all at length he receives baptism. Faith, therefore, has been present before he receives baptism. Faith, then, is not given in baptism. But when an infant is offered the question is asked whether its parents offer it for baptism. When they reply through witnesses that they wish it baptised the infant is baptised. Here also God's promise precedes, thus He regards our infants as belonging to Church no less than those of the Hebrews For when they who are of the Church offer it, the infant is baptised under the law that since it has been born of Christians it is regarded by the divine promise among the members of the Church... By baptism, therefore, the Church publicly receives one. who had previously been received through grace. Baptism, therefore, does not bring grace, but testifies to the Church that grace been given for him to whom it is administered.
Perhaps it seems this position swings the pendulum too far the opposite direction of the Anabaptist view by focusing too much on the community and not enough on the individual. If this were all the stance offered it would be true. However, those who baptize infants are not so foolish as to neglect the choice of the child. After the baptism the community seeks to raise him/her as a Christian and when the child has reached a level of maturity in experience, education, and mental capacity to respond to their sin, Christ, and the Church then they may be "confirmed." Confirmation is a ceremony in which previously baptized members of the Church stand before the community, after accepting the required theological education, and officially accept their baptism. Whereas at their initial baptism the individual was accepted by the community and God, so now at the confirmation he/she officially accepts God and the community by accepting the legitimacy of their baptism with a commitment to live up to the baptism for the rest of eternity. If, in their maturity, the individual does not wish to accept their baptism then they are free to do so and consider themselves to have been given an overly celebrated bath early in life. In doing so the individual is released from the Body of Christ and mourned over greatly for they have chosen to not accept the love, grace, and life that was given to them from every holy influence that raised them.
What are your thoughts on the matter? Are you persuaded that infant baptism should be practiced, doesn't cause harm, should be avoided? Have you been given a different perspective on the issue? If so, will you please share perspectives you have encountered?

That's a poor argument. You can do this without baptism and I've been to churches that "dedicate" their child to God and exhort the community to accept the child. To say that because a church doesn't baptize an infant that it's then looked at as an alien is ridiculous. And I don't think churches that baptize children are any better at accepting children than those that don't.
Second, baptism is likened to circumcision in the Old Testament. Yahweh commanded his people to be circumcised (a discipline focused only on males)
Exactly why it wouldn't mean to baptize infants. If you're going to be consistent, then only male infants should be baptized. And If what you're saying was true, God would have been just as clear about the importance of baptizing infants as he was about circumcision. But the fact is that there's not one scripture telling us to baptize infants and every scripture that shows baptism is with someone choosing to be baptized.
After the baptism the community seeks to raise him/her as a Christian and when the child has reached a level of maturity in experience, education, and mental capacity to respond to their sin, Christ, and the Church then they may be "confirmed."
There's no scripture where God says to do this or even says anything about being confirmed.
Personally I believe the matter is determined by what the new testament says about the nature of the Old and New Covenant. Israel was the old Testament community of God in a corporate manner. The New testament presents the New covenant as different, and that it's very strengths are that it is individual in nature, and is a covenant with all of those who are saved. That is why the New testament also focuses on baptism as a declaration or a response of a good consience towards God and a declaration of faith. It is because of the individual nature of the New Covenant.
@musterion99@xanga - Those are some great points, I agree entirely.
@Happily_Married_Guy@xanga - Thanks.
That is why the New testament also focuses on baptism as a declaration or a response of a good consience towards God and a declaration of faith.Good point. Emphasis, good conscience, and declaration of faith.
@musterion99@xanga - You took the words right out of my mouth. Good job.
@xhalesx - Thanks
I believe in infant baptism for several reasons:
1.) As you mentioned baptism is seen as the "circumcision" of the New Covenant, and even Our Lord was circumcised as an infant.2.) The Church has practiced it for ages and ages.3.) If infants cannot be baptized then there are over a billion Catholics including the Pope, Mother Theresa before she passed (is she in hell now, then?), myself and my entire family that are not really baptized and that is a tremendous problem.4.) Following that, this means that Protestantism was begun by an unbaptized man (Martin Luther, who was baptized as an infant) which might be problematic for some...5.) More importantly, we have inherited Original Sin because of the choice of our first parents in Eden. If our very nature is affected by their choice, how much more important is the choice that our direct parents make in choosing to have us baptized, undoing the choice made so long ago that we might inherit not death, but eternal life?6.) Finally, and even more important and probably the greatest reason I believe in infant baptism is this: baptism and the graces we receive are absolute, total, 100% free and unearned gifts from God. Totally gratuitous. Utterly lavish. Is this reality not most perfectly realized in the baptizing of an infant?
To equate baptism with circumcision is a mistake based on an idea that says the Church replaces Israel -- a concept foreign to the Bible.
As you said, baptism is an outward expression of our faith in Jesus, but it is also an ordinance instituted before Jesus' time, and according to Him, required for salvation. It had to be administered, as Paul indicated by one having the authority to do so. Ordinances are only administerd to those who have the spiritual maturity to accept them.
@musterion99@xanga - That first argument you address is based on the notion that baptism is the seal of salvation and entry into the Body of Christ. If that is how we view baptism then how can we say a baptized person is as much a part of the Body of Christ as an unbaptized person? I'm not sure we can. But again, if one does not believe this is a purpose, function, or affect of the baptism then the argument has little ground to stand on. That's the notion I'm inspecting.
It's funny, I approach the circumcision/baptism parallel from the opposite perspective. It seems unnecessary to me to mention the need to baptize infants in the NT because the parallel between the two ordinances is so strong. The biggest difference seems to be the progression from males being the only ones practicing to both male and females. Why a party (infants) would be eliminated from this parralel without mention doesn't make sense to me. It seems to me more likely that if baptizing infants wasn't part of that new covenant ritual it would be mentioned when paralleled with a former ritual. Further, I'm not persuaded that moving from a male only practice to male and female practice shows inconsistency. I'd say it shows progression in revelation of the kingdom of God. I think that is a theme we see a lot in the NT.
As for infant baptism not being directly in scripture, I agree. But that doesn't mean it wasn't a practice of the community. It simply means it isn't addressed. Many believe the passages that mention entire households being baptized may be implying their children were a part of that household. I think some may point to Acts 2:38-39 as well but I'm not sure that has much weight to it. That passage seems to be emphasizing salvation belonging to the children more than the sacrament of baptism itself. It's an argument from silence I suppose. Nothing in the NT says "do" or "don't baptize infants" and I'm not persuaded to take the position of Zwingli (even though I quote him in this entry) that we should abstain from activities that are not directly commanded in scripture. I'm more inclined to take the Luther approach and avoid what is forbidden. Scripture never gives an age requirement for baptism so looking to church history is helpful at this point. So far in my research I've found the practice being documented as far back as 300 A.D. I'd like to find some earlier accounts though before I'm completely persuaded by it. When it comes to confirmation I suppose I'd say the same thing. I'm sure we could look at the church liturgy and find a number of accepted practices that are explicitly in scripture (like fasting for lent and such).
What are your thoughts on all that? Thanks for contributing!
@Happily_Married_Guy@xanga - I agree that the Church does not replace Israel but Paul seems to convey the idea that the Church is Israel in his letter to the Romans. Do you think the parallel of the two rituals requires a replacement theology or do you think the former can exist without the latter?
@Ancient_Scribe@xanga - I recently posted a letter by Aristides on my blog. In it he writes of the Christians and how they celebrate the death of their infants because they believe the child has passed through the world without sin. How do you respond to that in light of your 5th point? If you did not believe in the doctrine of original sin would you still be in favor of infant baptism?
The denomination I belong to abides by the following; "(We as individuals-and as a whole group)--cannot (in our own sinful flesh condition) believe in Jesus Christ, nor come to Him--the Holy Spirit has called (us) by the Gospel" As Jesus Himself said "Of (the faith of) little children is the Kingdom of God.
2 other observations: I know of one Baptist couple on my mother's side of the family who was put in an awkward position--they decided to have their infant child baptized before the child died at less than a month old.
I'll put this one out there: How would you answer this--what about aborted babies then, (since they don't get the opportunity to be baptized?) (A pastor in my denomination believes that those babies would end up in heaven--)
@TheGreatBout@xanga -
That first argument you address is based on the notion that baptism is the seal of salvation and entry into the Body of Christ. If that is how we view baptism then how can we say a baptized person is as much a part of the Body of Christ as an unbaptized person?It's not the seal of salvation. That would mean that just because these infants were baptized, they are assured of salvation, no matter how they live the rest of their life. And we read in Acts 10:44-47, where some were saved, received the the Holy Spirit, and spoke in tongues BEFORE they were baptized.
It's funny, I approach the circumcision/baptism parallel from the opposite perspective. It seems unnecessary to me to mention the need to baptize infants in the NT because the parallel between the two ordinances is so strong.
That's bad hermeneutics and you're using eisegesis. Why wouldn't God just clearly proclaim that infants should be baptized when this would be a VITAL doctrine? And why wouldn't we see even one clear example of an infant being baptized in scripture?
The biggest difference seems to be the progression from males being the only ones practicing to both male and females.
Yes, that's a huge progressive jump you are insinuating without any biblical backing.
It seems to me more likely that if baptizing infants wasn't part of that new covenant ritual it would be mentioned when paralleled with a former ritual.
Well, it doesn't at all seem more likely to me because it's not even a valid analogy in the first place.
Further, I'm not persuaded that moving from a male only practice to male and female practice shows inconsistency. I'd say it shows progression in revelation of the kingdom of God.
That's just your personal opinion based upon you doing eisegesis and without any valid scriptural backing.
As for infant baptism not being directly in scripture, I agree. But that doesn't mean it wasn't a practice of the community. It simply means it isn't addressed.
And I'm saying that it's only logical that if this is something God wanted, he surely would have made it clear in scripture.
Many believe the passages that mention entire households being baptized may be implying their children were a part of that household.
I don't care if many believe that. Again, they're IMPLYING it through eisegesis. God could have easily stated that there were infants in that household. So far your arguments are very weak.
@TheGreatBout@xanga - "When a baby is born to one of them, they honor God, and if it should happen that the little child dies, they honor God even more, for it has passed through the world without sin."
This is pretty ambiguous, however, I believe it could be understood as referring to the fact that because the child died so young it was able to pass through life in this world without having committed any sin of its own choosing. It isn't clear if this passage is referring to stillborn infants or infants that die before being baptized but in light of the high chance of infants dying shortly after birth, children were often baptized very soon after.
As to your question of original sin: if I didn't believe in it, I would be a heretic I imagine! If there is no original sin/fallen human nature, why then are we suffering today when it was only Adam and Eve that sinned?
@musterion99@xanga - Sorry. Seal was a poor choice of wording on my behalf. In no way do I believe baptism eternally secures someone from sin. And I don't want to be like the men in Acts 15 who say "if you do not perform suchandsuch a ritual you can not be saved" because we all know salvation is a gift of pure grace received by faith and not by mere ritual. However, I admit that rituals are some of the good works that accompany such a saving faith. I also admit that baptism is absolutely necessary for all who wish to be united with Christ (Mark 16:16). Perhaps it would be better to say baptism is the declaration of salvation and of belonging to the community of faith. At least that is what it has been considered through time. As we agreed earlier it is the outward expression of an inward faith/commitment (though I clearly believe it is not solely that but has communal implications as well). To scripturally support the notion that baptism is one of the tools that brings one into the body of Christ many point to 1Corinthians 12:13a as well as the obvious practice of the early church in Acts to baptize all new believers.
Again, if the parallel between circumcision and baptism is strong (which most commentators seem to agree it is) I'm not convinced an example and direct command -that would be implied- would be necessary. It'd be redundant. Those trained in the Torah and Jewish life wouldn't need the parallel spelled out for them. And it is even possible it was explained and not set into the scriptures. It'd be nice for folks like Zwingli but, again, I think Zwingli's position of only doing what is directly commanded in scripture is misguided. I can't agree that because something is not explicitly commanded it ought to be dismissed because I believe their are implications in scripture and teachings/practices found in the early church that aren't explicitly drawn out in scripture. This is why it is important for me to find documentation of infant baptism before 300 A.D. if possible.
Here is some Biblical backing for the progression of male circumcision in the Old Covenant and both male and female baptism in the New Covenant. Male circumcision: Genesis 17:1-14, and John 7:22-23. Male and female baptism: Acts 8:12, 16:15. And for funsies; Parallel between circumcision and baptism: Colossians 2:9-15. Verses that some say may imply child (and female) baptisms: Mark 2:38-39 ("every one of you"), Acts 16:15, 33; 1Corinthians 1:16 ("household").
And again, I'm not convinced of this argument yet. I'm just investigating it. One question I ask is "if children belong to the kingdom of God already then why must they be baptized?" However I do worry that question can lead to us trying to draw lines in the sand about age and can set us onto a journey of rules and legalism. But then what doesn't have the potential to set us on that road when trying to understand the kingdom?
@Ancient_Scribe@xanga - I don't think we can say that not believing original sin means only Adam and Eve have sinned. I don't think any one can be Christian in the fullest and say anyone but Christ has lived without sin. I think one can say that even if they do not believe in the doctrine of original sin they can believer every human a sinner, for every human sins. That being said, I do believe we are all born into rebellion against God because of Adam and Eve ;). I still need to e-mail you back. Life has been hard. I know I said I'd be sending you a message and I haven't. My apologies brother.
@WLCALUM@xanga - I don't know how to answer your question because it is ambiguous. What about aborted children? Are you asking if I consider them to be with Christ in paradise or are you asking if I consider them as initiated into the Body of Christ on earth? To the first I say yes and to the second I say no since they are not fully yet on earth. But they definitely belong to the kingdom, as every child does, baptized or not.
Good conversation here....
It would serve everyone well to examine the idea that circumcision is not best described in the New Testament by baptism but rather regeneration (The act where God gives His grace to open the mind of a person to come to faith). Colossians chapter 2 describes this best. It is not describing baptism as mentioned above. Baptism is done with the hands. The sign of the new covenant made in Jesus own blood is described in Jeremiah and in Hebrews as God writing His laws on minds and hearts. This is regeneration. Baptism is a rite that is to be given to only those that by confession give evidence of that regeneration. It is never given in the “hope that the person receiving it will one day come to faith.”
One of the best debates a person can listen to on this subject between 2 brothers in the Lord who love and respect each other is located here.

Well worth the listen! I myself felt Dr. White held the better arguments and won.... Truly would love to hear what some of you think. Perhaps some of you could message me your thoughts should you choose to listen.
Grace and peace!

I scripturally showed you there were people who were saved before being baptized.
And again, I'm not convinced of this argument yet. I'm just investigating it. One question I ask is "if children belong to the kingdom of God already then why must they be baptized?" However I do worry that question can lead to us trying to draw lines in the sand about age and can set us onto a journey of rules and legalism.
It's a much better alternative to leave the age thing in God's hands then to eisegete a doctrine that God chose to not clearly define. And what you are doing is legalistic by saying an unknowing infant needs to be baptized.
@musterion99@xanga - Of course infants don't have a saving faith (that we can be aware of anyway). I'm not saying they do. I have not tried to made that argument. It seems we are going in circles with this bit. One of the things I'm trying explain about this notion is that baptism is not solely an outward expression of an inward faith but it is also an expression of a community's faith, both parties commitment, both parties uniting with one another and both uniting with, through and for Christ. I've also tried to show that this stance sees another aspect of baptism is the marking of a true member of Christ's body and it is paralleled with a former covenant's sacrament. I feel I've sufficiently presented the cases for the perspective that promotes infant baptism to a point where we can say the proponents of that stance don't find need for an individual to be an adult for such a sacrament but do find need for the individual to publicly express their faith they have reached a certain level of maturity.
You did show that people were saved before baptism. It's true. I don't at all disagree with that truth. I'm not trying to say people are saved by baptism, especially not with that comment you cited. In fact, I pointed this out earlier in that paragraph when I stated, "And I don't want to be like the men in Acts 15 who say 'if you do not perform suchandsuch a ritual you can not be saved' because we all know salvation is a gift of pure grace received by faith and not by mere ritual." However, in the segment you cited I was speaking of being united with a community which is the body of Christ. One can't deny that the baptism is one of the marks of a member of Christ's body (Acts 2:38-41, Romans 6:4, Ephesians 4:4-5, Colossians 2:11-12, etc.). Of course grace precedes baptism. We all agree on that. But that isn't the issue in my comment. My comment was concerned with baptism being a mark of a member of Christ's body. Acts 10 showcases that the Spirit fell on people before they were baptized. But as a result they were baptized so they would be recognized as official members of the body of Christ. It is this aspect of baptism I was referring to in the comment you cited. I hope that helps clear the air on that.
Also, I'm not at all saying an unknowing infant needs to be baptized and so I'm not doing anything legalistic. Again, if you read my words (which you cited right above your comment on them) you'll see I'm investigating a notion and that I'm not convinced of the notion. I've said these things a couple times now. I've tried to make it clear that I'm being challenged in my thinking and examining an idea and not preaching an idea or demanding it be practiced. If that was not clear before I pray it is now. I'd hate for us to misunderstand one another and start deeming one another sinful or legalistic out of a misunderstanding.
Would you say you are against infant baptism or simply not in favor of it? Do you find it wrong or just not commanded and possibly off the mark? Again, glad you are contributing to the conversation!
@MC_Shann@xanga - Good comment! I think one of the biggest arguments for the stance of infant baptism is that baptism is the mark of a member of the Body of Christ (as is partaking in the Eucharist). Do you think, on that alone, the stance has legs to stand on or do you think by putting emphasis on that aspect of Baptism (to justify infant baptism) one must neglect other aspects of it?
@TheGreatBout@xanga - I meant "with Christ in paradise (heaven)"
@WLCALUM@xanga - Ah. Yeah I hold the orthodox belief that children and unborn fetus' go to paradise.
@TheGreatBout@xanga -
I've also tried to show that this stance sees another aspect of baptism is the marking of a true member of Christ's body and it is paralleled with a former covenant's sacrament.I know that you've tried to show a lot of things, none of which are backed up scripturally, except in your eisegeting of scripture.
I feel I've sufficiently presented the cases for the perspective that promotes infant baptism.
Sufficiently? You have a very loose definition of sufficient.
You did show that people were saved before baptism. It's true. I don't at all disagree with that truth.
Which should also tell you baptizing an infant without it having knowledge is ridiculous, to say the least.
One can't deny that the baptism is one of the marks of a member of Christ's body.
Yes, believer's baptism, which is the only thing we see in scripture.
Also, I'm not at all saying an unknowing infant needs to be baptized and so I'm not doing anything legalistic.
That's a cop-out and just semantics. If an infant doesn't need to be baptized, then why do it? If it's done, it's because it needs to be done. It's God's will that it's done.
I've tried to make it clear that I'm being challenged in my thinking and examining an idea and not preaching an idea or demanding it be practiced.
Good! I hope you examine that you haven't backed anything up scripturally except to use eisegesis, in which case anyone can use to promote any doctrine they choose.
Would you say you are against infant baptism or simply not in favor of it? Do you find it wrong or just not commanded and possibly off the mark?
I don't think it's a sin but not something that should be practiced. If what you say about the infant becoming a part of the body of Christ and community were true, then I believe without doubt that God would have surely and clearly spelled out in scripture that this should be done considering the ramifications and importance of it. it makes no sense to me if this was the case, that God wouldn't give scripture on this. Maybe to you it makes sense, but certainly not me. But even so, God is sovereign and I don't believe a person's salvation would hinge upon whether or not they were baptized as an infant.
@TheGreatBout@xanga - If we simply believe that all human beings save Christ (I'm intentionally not mentioning His mother lest I open another can of worms in our discussion) have sinned and that is simply the way of human nature or, as you have said, "we are all born into rebellion," I think the danger is that without a teaching of original sin it seems that God created us as sinners in the first place...
Rather, the doctrine of original sin teaches that humanity once existed as holy and sinless as it was created by God. But by the sin of the first two human beings we have come to inherit a fallen nature, a nature wounded by sin; what once was meant to dwell always in the presence of God now is born apart from Him.
As I have said before, you needn't worry about emailing me; be faithful to what and where Christ is asking you to be in each moment, and if He asks you to take moment to email me, wonderful. If not and you are yet being faithful, I am equally satisfied! If you are being faithful and you are loving Christ, that tells me far more about how you are doing than even the most detailed account written in an email.
Baptism is a practice that far predates Christ. Jews made ritual cleansing a regular part of their lives, and the truth is, they weren't the only ones. Many religions have used ritual cleansing for many centuries. I believe Christendom has made an idol of "baptism." Why do we treat baptism as something that will preserve or send you to Hell, but we almost completely ignore fasting?
@TheGreatBout@xanga - If you could list those scriptures in romans that say the church is Israel I would be interested in looking at that.
As to you question "Do you think the parallel of the two rituals
requires a replacement theology or do you think the former can exist
without the latter?"
It's a matter of semantics I believe, so to focus too much on that gets away from the real issue, which is, what is the nature of the New Covenant? If what you are saying is true, than the New Covenant has essentially unchanged, and has retained its nature in transition from the Old Covenant to New Covenant. What is it's nature, is it corporate or individual? Hebrews 10 seems to indicate that the New Covenant has replaced the Old, and that it has different characteristics and strengths, one aspect being that it is individual. It also now is made with those who have personally experienced God's saving grace and partaken in it.
Circumcision cannot be used as an analogy for the New Covenant, as it was the Old Covenant sign. It was a sign used to mark a national people as God's people. Today there is no national people that have this relationship and are subject to the theocracy that accompanied it. This is because the fundamental nature of the Covenant has changed. Now all nations are welcome, and the heirs are only those that are saved and can thus be called God's people. Unbelieving babies and children have not become part of the people of God that are in Covenant with Him (yet -- God willing), although I believe babies and children are capable of saving belief, such as Jeremiah and John the Baptist.
You will notice that I have not argued modality in Baptism. This is because it is oft repeated that "Baptism means immerse" while it can, it also means cleansing, and proofs such as "they went down into the water" can also just mean they stepped in water. I believe the proper mode is immerse but the evidence is largely circumstantial, it is not good to build a case on it like most Baptist literature does. The strongest argumentation is the nature of the Covenant, and to whom it is applied.
