The Church belongs to Christ, as He states: "...I will build My church, and the gates of Hades shall not prevail against it."
How do you propose the Church became Constantine's? How was he able to overcome the will of God? If, as you propose, Constantine managed this, how do you propose that he was able to deceive all of the Christians of the day in to believing that the Church was still Christ's?
I will gladly respond to reasoned arguments. Its hard for me to respond to accusations of wearing blinders.
OK, we are using common terms, but with seemingly different meanings. Please define "the Church". Also God allows sin and disobedience (which is anything against His will) to happen all the time, but He does not approve of it, Constantine is no exception.
One need not overcome the will of God in order to usurp a physical organization. Nor does one need to overcome the will of God to lead others astray.

Hmmm. Did IQ's drop suddenly - state religion, forced conversion at sword point - do these things ring a bell?
