I went to a non-LDS church and they asked people there for the first time to raise their hands.
Each week they do this and each week people raise their hands.
If I think back to the mormon days, when this happened it was almost always family visiting. Almost never a new investigator.
I am not a Mormon but I posted a thread about Mormon background checks on new "converts." If they find someone is a predator and there is proof, are they so desperate for converts that they would allow that person to remain?
