You are beginning to worry me. I don't think anyone would claim that the Church "wrote" the Scripture -- the Church selected the books that were to be included in the New Testament canon, twenty seven or so books out of an abundance of over 200 different sources pretending to be inspired. And it took the learned people of the Church some 350 years to accomplish that!
The Scripture on which the Church was founded was the Greek-language Old Testament (Septuagint, LXX), which you Protestants don't use, which was translated from Hebrew into Greek by 72 Alexandrian rabbis some 200 years before Christ was born.
But the New Testament is the product of the Church, and the Church teaching is in concordance with the Old Testament and the New Testament, you can be sure of that.
And the difference is????
Not even the early church fathers would have the adacity to make this kind of statement nor was it ever a view of the Church that "they put it together". Someone here directed me to Ireaneus. I'd suggest that some should reread his views on the holy scripture.
BTW-If you don't think someone would overtly claim the Church "wrote" the scripture please see post 19 of Why We Have a Ministerial Priesthood
