Ummm, the creation of the New Testament...was written by the Apostles (and Luke), long before Christianity had anything to do with the Empire, and was in fact a persecuted minority. Even the recognition by the Church (long before the invention of the papal supremacy of Rome) was done BEFORE Emperor Constantine accepted and favored the Church.
You are right though, Roman Catholic "tradition" did not give us the bible, the Holy Spirit inspiring the First Century writers did that, and the Holy Spirit inspiring the Church's recognizing the various books authenticity (RECOGNIZING, NOT CREATING) later in the 200s+ finalized the canon.
The inability of RC's to distinguish between recognition and creation is astounding, IMHO.
BUT:
It's Da Vinci Code fiction to think "The creation of the bible and the federalization of chirstanity in the Roman Empire was done so to consolidate power by the Roman Emperor," however.
I have not read the Da Vinci Code, nor do I wish too. And I was stating 'politics 101' in 'consolidating power'. It is your fault you don't understand that.
