Before we condem, how can we be sure that this branch of the church is not trying to minister to these sinners. Just maybe, they want to get the sinners in and then work with them. Will a sinner come into a church on their own? Unlikely. If the organization seems to appeal to the sinner, he or she might get involved.
Unless a freeper actually attends one of this groups sessions, how can we really be sure what the outcome is.
