I don't see this necessarily contradicts the traditional understanding of Christian faith as the Lord used human condition to reveal his love and salvation. There are, of course, a series of articles of faith that should be the same for all cultures.
Not true at all- #1) Since we know that God created this world, you and I.. #2) He wouldn’t make salvation hard to understand nor make it dependent up on human “wisdom”, He’d give us this salvation directly (as He did both in physical form-and in written word when He wasn’t “here in the flesh”). 3) God doesn’t use pagan societies to inspire scripture, and never has, He supernaturally revealed His word, Himself through His chosen peoples.
>> I never said all ideas were borrowed
Well, yes, you did. You said (and I quote):
“When Christianity evolved in Europe, it >>only<< appropriated/borrowed cultural ideas and practices”
