Unam Sanctam Catholicam just published another important article related to evolution theology HERE.
I agree with USC's position, and I'll offer a couple of my thoughts.
I understand the apparent need to make all things fit into the most current scientific hypotheses, nobody strives to be the object of the "knuckle-dragging" jokes so often directed towards anyone who strictly adheres to Church tradition. But, to believe in God while accepting scientific principles does not necessarily demand, as I saw in a Catholic school last year, the use of timelines describing on which day of the Biblical Creation cycle it was that dinosaurs appeared or when furry critters began climbing trees. As smart as we think, as we hope, ourselves to be, we must remember the one basic principle that science and scripture clearly agree upon: There is always knowledge which lies beyond the science of Man.
I may have related this before, but there was a time as an undergrad that, inspired by Carl Sagan, I deluded myself into thinking that I could excel at astrophysics...that was until I realized that they were serious about the "physics" part.
My enthusiasm for the cosmos happened to coincide with a NASA deep-space satellite passing by Saturn. NASA received images of the rings of Saturn. The images revealed certain abnormalities of orbit.
The next day, in our morning lecture, the head of the department (did they all TRY to look like Einstein or was it just coincidence?) rushed onto the stage and climbed up onto the lab table. He raised his arms into the air, and casting his eyes upwards, he shouted as if he cried out to heaven, "Today, the laws of physics have changed!"
The impression I had that day, that science "law" was a house built upon shifting sand, has never left me. In fact, at that moment, the House of Science seemed more like a houseboat on the wide Mississippi; however, instead of navigating the strong central current in the middle of the river, it seemed to perpetually drift and bounce along the shoreline, its route subject to a constantly fluctuating current, at the mercy of structural obstacles and inflowing streams.
I still wonder if the little houseboat will make it out to the center of the river or just sort of bounce along until the Big Dump into the great ocean.
