I did. I've got the Anti-Nicene Fathers on my computer in PDF, so I did a search for that term. None of the early Christians ever used that term. It's what everyone—I'm always being accused of that. Oh, David believes in baptismal regeneration, even though I have never used that term in any message I've given. I don't believe in it, whatever it's supposed to mean. And like I say, the early Christians never used that term, but somehow that label is always stuck on there.
So to just get it straight, the early Christians believed that baptism is a channel of God's grace. It's not merely something that's symbolic or something that's a step of obedience.
