The church I attend is part of the Southern Baptist Convention.
That's neat, I don't consider myself religious at all, but I know the Southern Baptist Convention is the world's largest Baptist denomination with more than 15 million members.
Yes, it is a large organization.  I don't know much about it's history.  Do you know when it was founded?
Yes it started in 1845 when the Baptists in the southern US split from the northern Baptists over the issue of slavery.
