As a Bible believing Christian, commited to upholding the integrity of the text of scripture, I would naturally take sides with yaddayadda on this issue.
In my opinion, Christanity, born into the world of humankind at a time and place that was a maelstrom of religious ferment and activity, had to fight all the way for its existence. Christianity first appeared as a development within Judaism, and the first controversies that the early Church had to deal with were those concerning the new faith's relationship to its parent religion, the most famous example being the circumcision debate described in Acts
As Christianity grew however, it had to come to terms with religious and intellectual movements that it met up with, often in an environment of agressive hostility, in the wider world. During those early years, the Early Church Fathers, our earliest theologians, had to evaluate these rival movements and try and establish a place for their own faith in relation to them.These early Christian Fathers were themselves for the most part, Gentile Greeks and Romans, and as they came to grips with their own faith and presented it to the world of their contemporaries, they were forced to relate it to the thought patterns of their society. Had they, for the sake of "purity" invented their own vocabulary and portrayed their religious thought in alien concepts, the religion of Christianity would have become a meaningless vacuity, and the true message, that of salvation being available to all, would be drowned in endless debate.
As the early Church Fathers grappled with several religious notions, many of which seemed to bear a superficial resemblance to their own beliefs, I believe they suceeded, not without disputation, in preserving the original message of Christianity, and its Author, in an atmosphere free from intellectual influence.
Those early years were not easy for this infant religion. Fighting off such twin problems as vicious persecution, on the one hand, and ambitious savants bent on hijacking the new faith on the other, it was a miracle that it survived at all.
