The Big Bang theory was hypothesized by the Catholic priest Georges Lemaître,
and some of his critics argued it was just an attempt to prove his religious beliefs ("let there be light"), he basically saw religious and science as valid but separate ways of knowing truth though and was actually uncomfortable with the pope claiming his theory was proof for Christian teachings about creation.
Darn! You beat me to it.
I was brought up Catholic and went to Catholic school throughout my formative years. I suppose that you could say that the Catholic church is not as hung up on the old testament as other denominations. The nuns told us that the book of Genesis is to be interpreted as an allegory that contains spiritual truths ( such as original sin) but not as a historical or scientific account of events ( Universe created in 7 Days, two original progenitors, etc...).
Likewise, we never had a problem covering topics in biology class such as early hominids, evolution, etc... why? Because it doesn't contradict the spiritual teachings of Jesus. It is the same reason why most Christians don't follow Rabbinic law and are able to pork, combine wool and linen, etc... as such rules have no bearing on "salvation".
You also have to remember that the Bible is compilation of various books, that were directed at different audiences, in different times, served different purposes and were written in different literary styles.
E.g: the gospels (accounts of Jesus' life) read different from the epistles ( directed at various early churches) which in turn read different from Revelation (prophetic revelation).
Likewise in the old Testament, the book of Psalms (hymns and poems) reads different from the book of Daniel (account of his life and revelations) which in turn differs from Deuteronomy ( civil law and conduct).
Scripture is not to be interpreted in a continuous fashion within a vacuum without understanding the context and purpose of each book.
