Of course the priest was not defrocked, as he did nothing to contridict the Church, Scripture, or Tradition. Scripture details the subjects of faith, and human’s relationship with God, not scientific exploration. I believe God could have written the Bible as a brilliant scientific treatise explaining every nuance of the natural world, but how would that have really helped us in Salvation and understanding God’s love for us? Scripture is about finding and hearing God, not measuring the stars or the age of the Earth. God prudently left such questions to our limited senses and studies so as not to overwhelm us with the intricacies and complexities of the miracle of Creation, a miracle that must first be appreciated and THEN understood. How could early humans, with no knowledge of math, physics, or even basic agriculture, appreciate the vastness of God’s Creation by simply knowing the details?
Put it another way: when speaking to our children about where babies come from, we don’t immediately delve into sexual reproduction and the combination of DNA, the passing on of mitochondria, the division of cells, because their understanding is simply too limited to appreciate it. Instead we instill in them first an appreciation of the beauty of life, and the sacredness with which it is conceived, only later to delve into the “dirty” details. I believe God did the same for our ancestors. Would Moses have appreciated DNA and cellular division if God had said that’s how we came about? I highly doubt it. Instead God told us about the necessities, about Adam and Eve, and the sin they passed on to our human blood, as that was more important to our eternal survival than any details about evolution.
A funny example I heard goes something like this: Early humans were speaking with God and asked “How did we come to be?” God, excited with the prospect of finally explaining the beauty of Creation to them, said, “I began with a spark of energy, which I formed into atoms, which I exploded out forming the foundation of the cosmos…” and God notices that the humans’ eyes are glazing over, so he stops and says, “I willed you into being with my Word,” and the humans looked at eachother and said “Aha! I understand words, this makes perfect sense now!” Only now, after thousands of years, have we truly embarked on understanding what, and how (in a material sense) God created this beautiful world.
It’s not a matter of either Creation or Evolution, but both Creation, Evolution, and whatever other glorious things remain hidden to us currently.
I highly recommend Catholic Answers own tract on the subject, catholic.com/library/Creation_and_Genesis.asp
