Trust me, I can understand where you're coming from. I can still remember a sermon from long ago (at a church I no longer go to) that 'IF YOU LISTEN TO ROCK MUSIC, YOU'RE A HYPOCRITE!" Even though rock music has proven to be a wonderful channel for Christian music.
Televangelists that show off their wealth and use the 'do as I say not as I do' form of teaching (like Jimmy Swaggert) aren't Christians in my book.
It's a possibility, but considering the admittedly little evidence offered (only a four-minute prayer and no plaintiffs and no complaints), I don't think this girl pulled a 'televangelist'.
No, the worse she was guilty of is a bit of naivete' and maybe the arrogance of youth. Maybe she really believes she did some good. Honestly, I believe in 10 years she'll look back on the experience with different eyes and see how something negative could come of it too.
And no plaintiffs, of course.
I wouldn't have sued either. I would have just made a point of avoiding her and those who went to her church. I've had enough of those people, thankyouverymuch :)
