From The Catholic Thing:
The obvious instinct of primitive men is to anthromorphise God-- to make Him a fellow-wanderer in the desert. It is the basis for paganism. To make gods like us.
The sublimity of Christianity-- the breathtaking truth-- is that God did become one of us, but remained God. He drew us to Him. He deigned to be One of us and suffered for us. He showed us the one divine trait not imagined in the Hebrew understanding of Him: courage.
Christianity drew out the shred of truth in paganism-- that God walks with man-- and then demolished paganism.
I have no patience for Mormon theology. It's a boys' theology, utterly lacking the sublimity of any real understanding of God. Chesterton provides a very satisfying hypothesis about its genesis.
Yet I have a great deal of affection and respect for Mormons. We had Mormon neighbors years ago, and they were the most gracious friends we've had. I have over the years spent quite a bit of time in Salt Lake City (for scientific meetings), and I have always come away with great respect for Mormon people and culture and for their transparent decency.
