Now just how do you come to that conclusion? I've never, ever been in an evangelical church that would take such a stance. Ever. Why do you assume this one would?
I have been in a LOT of megachurches, and I think the typical message about how to pass on the faith is to make sure that you are "plugged in" to a church, a youth group, etc. I have never heard a megachurch pastor say that the influence of the parents is the sine qua non. If you think about it, if they DID say that, then a lot of their justification for existence would evaporate...no need for youth programs, camps, etc. Just work on the parents and teach them to pass on the faith. But that is not the way of the megachurch, the program driven church, the segregation by age church.
