The greatest persecutor of the church is the church. Sometimes I think it's better for these people to be Mormon than not go to church at all. Let them be. At least someone is trying to save souls. We can't even do a fraction of what they're doing. They may have gotten their theology wrong but they still believe in Jesus and for all you know, that might actually be enough to get them to heaven. I'll take my chances and let them be. Mark 9:40
