If you are a former Baptist, then tell me the differences you have noticed
There are Baptist who disagree with you on what the Bible says concerning salvation, free will, the elect, etc.
Historically Baptists have divided over several issues including whether Christ's atonement extends to all people: "General" vs. "Particular" Baptists.
In the area we have been discussing, differences in theology run from Free Will Baptist teaching the traditional Arminian position to the Calvinist Reformed Baptist and in between the Southern Baptist Convention. The SBC left the Baptist World Alliance over issues including homosexuality and women in the clergy.
It might be interesting for you to find where your church stands on these issues.
