Miles: “Further, you are mistaken in saying that the Council of Sardica - which recognized appeals to Rome - was not received by the East.”
Truth Defender: ‘Negative. At the time it was held the Eastern Church didn’t accept it. That is history, without being rewritten by Rome at a later date and with new leadership in the Eastern and Western churches.’
You said Sardica was not accepted. Sardica was a local council held in the West; which later was explicitly accepted by the Eastern Church. What you have, here, is a positive proof that the undivided Church accepted the right of appeals to Rome. There are no ifs, ands or buts about it.
I've already explained why the author said that. But, here it is again: When the Council was finished, the Eastern church rejected its statements. It was only much later, under new leadership of both the Western and Eastern churches that it was debated and agreed to. Originally it was not accepted by the Eastern church - which is what was said. No if, buts, or ands about it!
