Missouri Legislature to Establish Christianity as State Religion: Part I

I heard about this a few days ago from Atrios, but my brain could not comprehend it. Honestly, I actually had to disregard it for a while at this risk of aneurysm. Chew on this for a minute:

The Missouri legislature could pass a resolution establishing Christianity as the state-approved majority religion.

Is this legal...possible...conceivable? How can Missouri have the balls to come out that directly in opposition to the separation of church and state? I'll have to let this one digest for a while before posting on it in more detail. What do you think?

P.S. Sorry for the lack of posts over the past few days. I've been busy at work.
