Of course that would be your response. If history does not support you just pretend that it does not exist. The authenticity of the False Decretals was first questioned by Catholic scholars. As for the quotations I have given, there are multiple sources for their authenticity. Even the Orthodox do not question their authenticity even though they would downplay or ignore their significance. The charge that they are too Catholic and thus must be forgeries is not scholarship. You might still hold that the Bible does not support Papal primacy but you cannot argue that it was not known by the ancient church or was never accepted by the Eastern church. To maintain such a position in the face of historical evidence to the contrary would just call into question one’s honesty and weaken one’s position in other areas.

Your Pope and his cadre will lead catholics right into the chrislam movement with catholics like you praising his ecumenism.
