"Here is a 1996 quote from Pope John Paul II:
Today, almost half a century after the publication of [Pius XII's] Encyclical, fresh knowledge has led to the recognition that evolution is more than a hypothesis. It is indeed remarkable that this theory has been progressively accepted by researchers, following a series of discoveries in various fields of knowledge. The convergence, neither sought nor fabricated, of the results of work that was conducted independently is in itself a significant argument in favor of this theory.
The Catholic Church also officially supports the Big Bang theory because it agrees with their theological position that time itself began at creation. By the way, when I refer to "creationists" in this pamphlet, I mean people who don't believe in standard science. The Pope certainly believes the universe was created by God, but he is not a "creationist" in this sense. "
