In this case because there are no graven images displayed. If you have never had the misfortune to encounter one of the literalist fundamentalist fanatics you are lucky.In the Baptist church my parents attended there was one. He was physically removed from the congregation twice for disrupting services by yelling and ranting during a service. After the second time he was told he would not be let back in the church ever. He tried to get in several times and was stopped at the door and forced back to his car by the deacons.
I’ve known some but they were Presbyterians. We didn’t allow pictures of Jesus in the Sunday School rooms.
