Honestly, that sounds like a great story, if you'd like to share it in more detail.
Ah, you know, 'mission stories.
My companion and I (girls) had just transferred into a 'district,' taking the place of a pair of 'Elders' (that's the boy type missionaries) the night before. We were told of the invitation to this meeting, and decided to accept it and explain that we were taking the place of the young male missionaries rather than simply ignoring the invitation.
So we showed up to some interesting looks, but were treated well. We were ushered to the front of the congregation, to chairs that would give us a good view of the pulpit and the preacher. (Of course, that put us square in view of everybody else in the congregation, as well....)
The preacher came in, we did all the opening songs and prayers. All was well. Then the preacher (who never looked once our way...) started talking about the differences between Christianity and the cults, especially Satanist cults like Mormonism. Now, my companion and I had heard this stuff before, but we WERE quietly looking around to see where the exit was.
The preacher wound himself up, probably wondering why his congregation wasn't getting as excited as he was. They, after all, DID see a couple of young women, modestly dressed, sitting quietly, while the preacher was talking about how the Mormons sent young handsome servants of the devil out to seduce, convert and spirit away all the virtuous young women in the congregation. He was pretty good, actually, at the oration. It all fell apart for him, though, when at last he swung around with his finger pointing and his sleeve waving..."AND SEE THESE MEN, SENT TO SEDUCE YOUR DAUGHTERS AWAY FROM GOD!"
Er.....
Chaos didn't QUITE ensue, but it was (once we got out of there without damage) funny.
Needless to say, we weren't invited back there. Needless to say, had we been, that's one invitation I probably would have politely refused.
