A Dogma That Has Forgotten It Is a Dogma

PZ Myers firing on all cylinders, takes down Alister McGrath. Here's his best response to one of McGrath's f(l)ailing attempts at reason:

Whoa. What happened to "of course there's no way you can bring those criteria to bear on God"? What about "God may not be in the same category as scientific objects"? One moment he's claiming you can't study god like you would the possibility of water on Mars, and next he's claiming the validity of using observation and theory to justify the existence of the remote and directly unseen. How … inconsistent.

McGrath also has some weird things to say about the Nicene creed. It's only weird, because the creed is really more of a mission statement for believers than an attempt at making a persuasive argument. And it is dogma, by definition. So you can't say you believe in the Nicene Creed, but you're not being dogmatic. That is what dogmatic means: asserting religious beliefs. But, whatever.
