Hey, check it out, Tristan Immanuel has posted Part 3, “How do you know baptism replaces circumcision?” of his two part brief on baptism. This is not his response to my critique but it is a beginning of an answer. I like the way it starts:

In response to my latest series on infant baptism, one critic wrote, “In your articles you state that the New Testament doesn’t argue against infant baptism, so the practice of infant baptism hasn’t changed since Old Testament times. But you never cite a verse in the Old Testament that indicates that infant baptism was ever practiced. If it was never practiced, why should it be continued?”Cute. Very cute. But it misses the mark completely.

I think this is a hoot! Can’t wait to see where it all goes.
