Primacy of HONOR??? You aren't aware of Church History before the Schism, are you. While I will say that Vatican 1 was NOT what the Church practiced in 500 AD, I think a look at Pope Leo and Gregory will give you a quick view on what was practiced BEFORE the Schism. The question is not "restoring the Pope to a position of honor". It is about "What WAS primacy"? It existed. But to what effect? That is the question before us. There is absolutely NO DOUBT that there was PRIMACY - now we must define it, brother. What power did Leo and Gregory have?

It's silly to get into a "first among equals but more equal than others" conversation.
And no we needn't define it. This is the same question debated each time Metropolitan Kirill Meets With Cardinal Walter Kasper.
