(Who are they now?)
All saved Christian saints (saved by grace through faith in the finished work of Jesus the Christ at His cross at Calvary and who alone is at the right hand of God the Father making intercession for the saved sinners who beleive Jesus is Christ. There are unsaved people who call themselves Christians but do not believe Gods Word is what it is, God's Word.
What I mean is among the baptists, which denominations of baptists are the descendants of these you've listed?
Southern Baptists, American, Northern, etc.....
I'm sure you understand what I'm asking.
