You wouldn't believe all of the people in my office who spout nonsense about the Catholic Church and her teachings that supposedly went to Catholic School.

Likewise...

You wouldn't believe all of the people in my church who were born and raised in it, went to Sunday School all their lives and still seemingly don't have the basics of the Faith in their lives!

I can understand it to some extent, since most young Christians are confused and conflicted, given our secular culture and schools. I can speak from personal experience. On the other hand, it's hard to understand people going through the motions well into adulthood. Reminds me of this verse:

Revelation 3:15-16

I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth.
