I hope that doesn't happen.
Most SBC Calvinists I know are comfortable with the Baptist Faith and Message, and it is around that confession that both Calvinists and non-Calvinists should rally. We can have our little family disagreements, and quite easily join forces to carry the gospel to the uttermost parts of the earth.
As for me, I am a Southern Baptist Calvinist and I'm not going anywhere.
Does discussion/disagreement over sotierology rise to the level of breaking the unity of believers in christ?
