I don't know. I do know that I grew up in a VERY legalistic household (Plymouth Brethren, if you follow). You MUST be baptized upon accepting Christ. You MUST wear hats if you are a woman. You MUST...blah, blah, blah.
Then I read the Bible. Nope. Romans changed my life.
Then I listened again to my pastor trying to tell me that Presbyterians were damned (I had no idea what that "P" word meant), because of baptism.
So...where do I sit? Probably more Baptist than Presby (or, rather, any pedobaptist). That said, I'm gonna give the biggest hug to my Presbyterian brothers and sisters in Heaven.
I think baptism should be an act of obedience and an affirmation of faith. Two of my kids were baptized Catholic. They are Christ-loving kids now who affirm that baptism as his Sovereignty in their own salvation--from Christ alone. I'm tired of Baptists telling me that they will only be saved if they're baptized again.
Aside from that baptism thing, what's the difference between Baptists and other lovers of Jesus?
