Is there anything in the Roman Catholic doctrine of papal supremacy that would prohibit the Pope from relinquishing his authority as head of the Church, and instead be "First among Equals?"
One of the fundamental differences separating the Roman Catholic Church from our fellow Christians in the Orthodox Church is the issue of papal supremacy. Rome believes that the Pope is the leader of the entire church, while the Orthodox believe that the Bishop of Rome is first among equals.
Given the pressure of secularism (both from outside and inside the Church), I believe that it is high time for us Christians who believe in the ancient faith to be united.
My questions is this: Given the Roman Catholic doctrine of papal supremacy, would it be possible, for the sake of Christian unity, for the Pope to relinquish that supremacy and become first among equals? Could he decide that it would be better for the universal church if he acted as "Prime Minister" of the faith, instead of "King of the faith?"
