There’s a really good blog by Gavin Ortlund at the Gospel Coalition titled, “Why I Changed My Mind About Baptism.” Ortlund lays out why he went from being an evangelical paedobaptist, affiliated with Presbyterians, to becoming a credobaptist. It’s quite fantastic because it raises the same issues I find in regards to continuity and discontinuity between the Old Covenant and the New. There are areas of continuity, but advocates of paedobaptism do not, in my opinion, handle the discontinuity well. You’d do well to read his blog.
