You tell me.
There are really two questions here:
1) What is a Southern Baptist?
2) What is a Southern Baptist church?
The answer to the first question can be pretty simple – a Southern Baptist is someone who is a member of a Southern Baptist church (whether they identify themselves as such or not.) We don’t have a membership outside of the local church membership.
But what is the sine qua non of Southern Baptist identity?
What makes a church truly a Southern Baptist church?
I usually write my opinion then let you interact with that. I’m going to make this more of an open thread, though I may write a follow-up post.
