I'll mention that I am a "Fundamentalist" Christian, but I know several Christians who believe in Jesus Christ as their personal savior but also believe God used evolution to accomplish His creation.
I do not think they are non-Christian because of it. I think they are misguided and are taking an improper view of the sufficiency of the Word of God and have to make illogical deductions about what Scripture says, but I think most Christians do that in some area of God's Word.
Proof: If Christians understood and followed the Word of God perfectly everywhere, even though we would still be hated (Christ was and He was perfect), non-Christians would not be justified in their hate.
Just my 2 cents.
