Is theology a mental illness?

A provocative title, to be sure. But let's consider some basic facts. A theologian is a person whom makes a living from exploring the nuances and deeper truths allegedly to be found in scripture. I've heard it said that it is the theologian's job to "think God's thoughts after him". First off, and call me short sighted, but why would any God need a measly human advocate to explain anything? Can't he communicate without 3rd party support? Clearly not, for down the ages theology has been trying to make sense of the commands laid down in scripture. Did you know that God condones slavery, ethnic cleansing, genocide, infanticide? This is a bit of a quandary for those who would have us believe that the Creator of the universe is all loving and all good. Frankly, the Bible is on par with any slasher movie, dripping with death and entrails, often delighting in such viscera. I'll get to the point; what theology amounts to is an attempt to defend the indefensible, to justify the obscene, the profane, the primal behavior of a tribal bronze age culture. Anybody who reads this blog already has a greater knowledge, a wider lens of experience and wisdom than any Bible character. Treat the Bible as myth and you might find the occasional gem; treat it as history and you're on a slippery slope. Treat it as a decent guide to morality, and you might as well turn the lights off on your way out.
