My daughter goes to a politically liberal church. I can tolerate it because the teaching is Bible-centered. They just like being on that side of the political world.
But an unredeemed person cannot tolerate true Biblical teaching. They will recoil from it. It will drive them away. In short, a CINO can be identified by watching how they respond to Biblical teaching.
My own pastor cannot tolerate parts of the Bible.
So...why do you continue to attend?
