"They believe that there is no salvation without Baptism. I believe if one is depending on anything, but the grace of God for salvation, then No, I don't believe that they are truly born again. I believe that the Bible teaches this doctrine. "
So, you're holding that VERY SAME DOCTRINE against Santorum the Catholic, right?
He's not a REAL Christian either, right?
I believe that the Bible teaches this doctrine, and it applies to anyone in any denomination that believes otherwise.
I'm not judging anyone, just saying.....
