Dogma and mysticism

I saw the following quotation on the Christian Century: 

Poet Christian Wiman says that “mystical experience needs some form of dogma in order not to dissipate into moments of spiritual intensity that are merely personal.” On the other hand, “dogma needs regular infusions of unknowingness to keep from calcifying into the predictable, pontificating, and anti-intellectual services so common in mainstream American churches.” Practically, this means that “conservative churches that are infused with the bouncy brand of American optimism one finds in sales pitches are selling shit. It means that liberal churches that go months without mentioning the name of Jesus, much less the dying Christ, have no more spiritual purpose or significance than a local union hall. It means that we—those of us who call ourselves Christians—need a revolution in the way we worship”
