This is not much different than what I experienced in my old IFB church when the pastor proclaimed that anyone who is a member of his church but goes and visits another church has committed adultery against his home church. So I left and joined another church and sometime after that, he and I were on the phone talking. He asked if I was going to church and I told him that I was and told him that I joined that church. Then we talked some more and as the conversation was about to end he asked me to visit his church. I asked him what about when he said that that would be the same as committing adultery against the home church he said, "Weeeellll, ..." and backpedaled big time.
Double standards.
