Phoemox,
I think you misunderstand Christianity; "Saying someone is wise, doesn't mean they are the 'source of logic'." Christianity teaches the Jesus Christ is the source of wisdom and understanding (which includes logic and math- please study these words in the bible if you don't understand this concept). But he is the source because he is God not because he was a wise man. Christianity teaches Jesus Christ is God in the flesh.
Wisdom (which includes math and logic) is in the nature of God which is why we understand it to be infinite, invarient, universal and not physical. So when you say something like this:
"Laws of logic are universal, there's no need to even have read the Bible to understand logic."
You miss the point. You as a non-Christian cannot rationally account for the laws of logic existing in a contingent physical universe of chance. Nor can you account for how it is that you can use universal immaterial logical laws, when your brain is not universal and is material. This is what you continually ignore.
