The article states (correctly) that one of the problems with creating rip-offs of Nirvana and Jay-Z for the Christian music scene is that you are trying to "shoehorn a message that is essentially about obeying authority" into an essentially rebellious medium.

The fact that this is correct shows how far "Christians" have strayed from the message of Jesus, who not only frustrated and angered the religious and secular authorities of his day but was an outright criminal and was executed for it. My Christianity causes me to question the so-called wisdom of our authorities, and I often find that they lack any wisdom at all.

My Christian music would be very anti-authority, but it would not be popular among today's "Christians".
