It is implied that Christian theology did not exist until the time of Christ or thereafter. If that is true, simply showing that theological elements existed before then the time of Christ suffices to prove that Christianity borrowed from pagan religions.

However, a cursory review of a few scriptures is sufficient to show that the New Testament authors believed that they derived their doctrine from the Old Testament. ([[#1|1]]). It is unfortunate that many Christian dismiss the Old testament Testament as being irrelevant, since they do not know how to derive New Testament teaching from the Old Testament as Jesus and the apostles did. Simply, they They lack the ability to read [[SP]].  Since NT authors derived their doctrine from teh the Old Testament, this pushes the date of the earliest Christian doctrine concerning Christ to the earliest recorded scriptures.
