Regarding the pastor. He should be more considerate of the whole situation including yours but not yours alone. Those “saved” very much need descipleing The ratio of those “saved” in prison and those in the church is about the same in my opinion.
Regarding Mohammed. Test the situation. Ask he what he heard in the sermon. What he has read in his Bible recently. But of course we better be able to answer such questions. His words will reveal his heart, just like ours do.
Regarding you and me. Maybe the flock is not to be safe in a worldly sense? I know what you are saying though but my reading of the Bible lately is that testing is appropriate and God gets involved personally, not from afar off.
I understand what you are saying: if we didn’t have our young children with us, I would be less cautious. But when you have a sex offender whose target age is the same as your daughters, you get very protective. We are also such a small congregation, less than 40 a Sunday, no one is anonymous.
Mohammed leaves promptly after service so it’s hard to chat.
