It's a theory, not proven at all. Just a general consensus of the day, which doesn't make it true. If you accept the "theory" of evolution you are rejecting Biblical scripture. If you then call yourself a Christian, you are reading a different Bible than the one I am reading. The Catholic church doesn't care whether you believe in evolution or not. They leave it up to your own personal interpretation, including the Pope. It doesn't matter to them as long as you believe humans acquired souls after being monkeys. Go figure.
rejecting WHAT Biblical scripture??
Many Christians (including the Catholic Church) not only accept evolutionary theory, but feel it is senseless to argue against proven science.
A true Christian would not judge others by saying they cannot be true Christians if they accept evolutionary theory (where does it say this in the Bible??)
