An overlooked passage on baptismal regeneration and infant baptism

Where I live, I suppose that most people could be called “Evangelical” or “Non-denominational” Protestant (though, we also have many Baptists).  One thing I’ve never understood about these groups is 1) The denial of baptismal regeneration, and, 2) the denial that infants should be baptized.  I think there is an underused passage in Colossians that deals with both things in a pretty good way.  Sadly, I don’t see it used so much.  This is Not to say that I never see this passage used, just that I don’t see it used very often.   As the King James Version of the Bible is the most well-known English Bible, and especially popular here, all verses will be from it.     “In whom also ye are circumcised with the circumcision made without hands, in putting off the body of sins of the flesh by the circumcision of Christ: Buried with him in baptism, wherein ye are risen with him through the faith of the operation of God, who hath raised him from the dead.  And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with, having forgiven all your trespasses; blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross”.  (Colossians 2:11-14). Okay, there is quite a bit more, but, as always, I want you to read it yourself.  I want to focus especially on v. 11, for now.  “In whom also ye are circumcised with the circumcision made without hands, in putting off the body of sins of the flesh by the circumcision of Christ”.  Okay, so, it’s important to remember who was circumcised as infants.  Male Jewish children.  (Leviticus 12:3).  As that is the case, why would we deny the circumcision of baptism to infants, if the Old Testament said that the circumcision according to the flesh was to be done to male children on the eighth day?  While it doesn’t say “hey, baptize this baby”, I would imagine that the earliest Christians (who were mainly Jewish), would see this, and say something like “Okay, then we should have our babies baptized”.     With regards to baptismal regeneration, I feel like these are probably the most explicit verses in the Bible.  “Buried with him in baptism, wherein ye are risen with him through the faith of the operation of God, who hath raised him from the dead.  And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with, having forgiven all your trespasses”. (Colossians 2:12-13).   Well, it seems to me, that if you’re forgiven of your trespasses, then you are, in fact, forgiven of your sins.  And you are forgiven of those sins, through baptism.  So, the Bible says that Baptism does something, and that something, is regenerating your soul.  Now, you may argue “okay, but a baby doesn’t have personal sin, why would they need to be baptized”?  That’s an article for a different day. As always, be sure to read the rest on your own, as it gives the context (I do not wish to write so much, as that would take too long). My point is this: baptizing babies is biblical, and baptismal regeneration are biblical.  It’s unbiblical to say there’s no biblical evidence of it.
