And then it will grow again with all the queers that will flock to become members of this perverted church.
I doubt it. Their crusades against Christianity aren't motivated by a desire to become full fledged members of the churches. It's motivated by a desire to ruin Christianity, which they feel spurned by and thus hate.
Won’t happen. The faithful will leave only to be replaced with a person who only goes once in a blue moon to get a feeling of absolution. They won’t be a part of the congregation other than irregular attendance. The older members will die off, the young heathens who run it will break the pigfy bank and reward themselves as they sell the church land and move to another congregation to finish out their lives in wealth and ease as any kids they have celebrate their pagan faith.
