Fair enough, but in what sense? If you mean that the Catholic church isn't teaching to the Bible, then I would tend to agree that echoes the sentiments of most former Catholics that I know. But isn't that what the article is saying, too?
The church is teaching fine, but not at the parish level, where (in many parishes) you won't hear anything about what the church actually teaches.
But it's more than just teaching; it's the liturgy, too. Lex orandi, lex credendi ("The law of praying is the law of believing", or more loosely: "how you pray reflects what you believe".)
If the orandi is vapid, childish mush, the credendi will follow obediently along.
But isn't that what the article is saying, too?
Yeah, in about three sentences, before going on to talk about how we need more liturgies catering to teenagers. Uh, no, actually, that's what we don't need.
