Where did I say the Donation of Constantine was a forgery? Yes, I made a claim, you asked me my source and I gave you the information. That's how discussions work.You have already admitted that the Donation of Constantine is a forgery and therefore not evidence of anything.
Also, even if it were not, it would be an Imperial document not a Church one.
That's not how a discussion works. You make a claim - you provide the evidence.
I assume from your lack of evidence that you have none.
I have yet to see you put forth where your information comes from other than you just saying so. This is why it is so important to research that of what another claims.
