Ex nihilo ad Omnium

Please excuse my Latin.
I was reminded earlier today of a key difference in Mormon theology and Catholic theology. That difference is the doctrine of "creation ex nihilo" or "creation out of nothing." What it basically means is that God created the entire universe from nothing.
Mormons believe that God "fashioned" the universe. He was more of a cosmic carpenter or watchmaker. Along with this doctrine comes the notion of divination and a procession of Gods (not to be confused with gods). For Mormons, there's a pseudo-doctrinal idea that God became God in such a way that mankind may also become God. This leads to a question of whether or not God had a God, and that God had a God.
However, St. Thomas Aquinas assures us that it is impossible for there to be an unending procession of necessary things (viz the Third Way). A necessary thing for Aquinas is something which is not "contingent," that is, generated and corrupted. God is neither generated nor corrupted. God is. "I am that I AM" He proclaims in Exodus to Moses. He is Aquinas' "first mover," that which cannot be moved by His own creations.
But what of creation then? Well, Genesis tells us that God "created" all things. Christians believe that God created all that is. The Big Bang theory suggests that everything that is exploded from nothingness. Is this the same? Perhaps it is. Nothing in the Big Bang theory suggests that there was no cause of the explosion. Perhaps God said, "let there be everything."
Then we come to the tricky business of creation of mankind. Evolutionary theory suggests that man evolved from an ape-like ancestor. Pope John Paul II allows for this, provided that humankind shares one original set of parents, an Adam and Eve, if you will.
But what about all the diversity in the world? We cannot hold to the assumption that in 6 thousand years (according to the Bible), the human race went from being 2 people of similar traits to all the different ethnicities to be found throughout the world. Furthermore, the Bible was not written in real time. The Torah was written about 1000 BC. At this point, everything written therein is orally handed down. So the question of the authenticity of the accounts comes into question (a topic which I hope to further discuss in later posts).
So, with this new information brought to light, what are we to think of humanity? Anselm, Athanasius, and almost every other theologian asserts that humankind was made in God's image and likeness. This is where I think our true question must be answered: If man is in God's image, how can we know this, and what does this say about evolution?
