It all comes down to politics. If the Catholics get enough Cardinals to buy into it -*-POOF-*- new Canon. All they need to do is pull together some savvy writers to make it all sound legit, like the early church fathers always believed it. Heck, now-a-days they simple say it's new teaching because the early fathers couldn't grasp the concept. The Church doesn't even try to tie it to the fathers anymore.
Mary will be eventually declared co-redeptix. It just takes time. One doesn't have to be a prophet to see which ways the political winds are blowing.
SO what it comes down to is you're sure. Okay.
