Some Catholics are not sure what to think of biological evolution. They hear from their evangelical Protestant friends and neighbors that it is contrary to Christian belief, but they do not hear much on the subject one way or the other from authorities in the Catholic Church. For example, the topic is never explicitly mentioned in the Catechism of the Catholic Church. My purpose in this article is to sketch in broad outline what the Church’s position has been and to answer some common objections to evolution made by Christians who are skeptical of it.
