Dogma is the guardian of mystery. The doctrines are spiritually significant in ways that we cannot fathom.
If you live today, you breath in nihilism.. It's the gas you breathe. If I hadn't had the Church to fight it with or to tell me the necessity of fighting it, I would be the stinkingest logical positivist you ever saw right now.
Let me make no bones about it: I write from the standpoint of Christian orthodoxy. Nothing is more repulsive to me than the idea of myself setting up a little universe of my own choosing and propounding a little immoralistic message. I write with a solid belief in all the Christian dogmas.
