Despite any impression my previous post could have made, the Big Bang is not a “Catholic” theory, not even a theistic theory, it is a scientific theory.
Nevertheless, it does bring a certain level of support to the point of view that our universe was created at some point. Before that, non-believers would hang on to the so-called “steady state model”, by which the universe, somehow, was “already there”, so to speak. Something like “Who created the Universe?” “I dunno, it was already there when I found it!”. In any case, that’s just more atheist-theist soap opera, as I call it. From the scientific standpoint, these theories stand alone and should explain things or be discarded. The Big Bang theory seems to be definitely here to stay…
Big Bang is not part of R-Catholic teaching, and I guess rightly so, after the Galileo embarrassment, when Cardinal Bellarmino and his group of 11 Pope-appointed theologians determined that the Earth being the center of the universe was scriptural and theologically acceptable, versus Galileo’s claim that the sun was the center of the universe. Both Galileo and the Church theologians were mistaken as neither are the center of the universe. Bellarmino was later made Doctor of the Church, I believe. Ouch. Really ouch.
