Does youth ministry function as a para-church ministry in the local Church?

I am reading a book titled As You Go by Alvin Reid with our youth pastor/family pastor. We just finished reading and discussing chapter one, which was a great discussion. Here are some of my favorite quotes from the chapter....

"We turned youth ministry into a toy department of the church." (p. 17)

 "We must connect students to the lager church and not function as a parachurch ministry within a church building. Students need older believers in their lives. We need Titus 2 revolution where older men teach younger guys and older women teach younger ladies." (p.20)

"We have communicated Christianity as behavior modification..." (p.38)

"American young people are unwittingly being formed into an imposter faith that poses as Christianity, but that in fact lacks the holy desire..." (p. 38)

"We need student pastors and national and parachurch leaders who are better at theology than a new ideas." (p. 18-19)
