interesting article. however, i think the juvenilization of a lot of evangelical christian worship mirrors the juvenilization (infantilization?) of north american society as a whole.
for example, look at the casual clothing middle aged and elderly adults wear now.
they dress like children...
What exactly would you like those of us older folks wear?
I think you're correct. I also think that juvenilization is not the only factor, that feminization plays a role too. I was saved in a juvenile/feminine seeker/finder church but left soon after when their weekly serving of mother's milk didn't satisfy my craving for all the mysteries of God. I was also put off by the hipster older pastors. A sixty-five year old man trying to look and behave like a twenty-five year old is just plain creepy, and I see it a lot in the seeker/finders.
