St. Paul teaches us in Galatians that Christianity is the acceptance of the belief that Jesus was the Messiah, that he died for our sins, and, through the power of God, defeated death, thereby giving the promise of eternal life to all those who accept that gift.
In Romans and other letters, St. Paul instructs us not to bicker about the denominational details (which is basically anything more than the first paragraph).
So porn is completely compatible with Chrisianity too? I think we need a more definitive answer, although I agree with you. Maybe the wrong question is being asked.
How about this, "define, based on what is in the Bible Christianities teaching about the origin of life."
And then this: "Does the Bible specifically say that types of living things were made "as is" or does it give 'wiggle room' for the idea that some species came from others?"
