Aren’t you lucky.
Why are they coming to your Baptist Sunday School Class? Do they want to be converted?
Otherwise, I think I would get the Sunday School supervisor to escort them out.
Actually they claimed to come just to attend Sunday school and church (SDAs in church on Sunday???) Before long we saw them actively "recruiting", trying to get our church members to change to their church. At this point I notified the pastor, who put an stop to their coming. That was around October, last Sunday 2 of them were back in Sunday school!!
I have tried to witness to them, argue with them... now I'm having a hard time being polite to them!!!
