But how was the authority and jurisdiction of the Pope of Rome actually understood by the pre-schism Church? How was it actually exercised? Can you confidently say that it was understood and exercised as it is now?
No. And I have made this clear on many, many occasions. The papacy, like many (if not all) doctrines of Christianity has developed over time. Thus, while the supremacy and universal jurisdiction of the Pope was latent in the earliest days, it has matured, naturally, along with the needs of the maturing Church which it supports. Newman and Fortescue offer reasonable explanations that satisfy your questions, IMO.
Now, I would only be speculating if I tried to suggest how someone living in second or third century understood the exercising of Rome’s authority (though I do think the writings of the ECF’s attest to the fact that the Church DID understand
something of it.) Of course, they lived under the rule of Caesar who governed from afar through the local governors and kings like Herod and Pilate, etc. In the absence of easy access to Rome, I think many matters were simply handled at the local level, but as Fortescue points out, modern technology has made appealing to Rome much easier. I can Skype with the Pope or be in Rome in a few hours if the circumstances required it. The Fathers did not have such luxuries, but if they had they would have USED them!
It will be interesting to see what concessions are made to Orthodoxy, but it seems to me that there is a lot more Catholicism in the first millennium than many EO care to admit.
I am very strongly inclined to think that the understanding of the papacy during the Church during the first millennium was rather different from how many of today’s Orthodox faithful imagine. I am rather skeptical about claims that papal primacy was a mere primacy of honor, and that the Pope was understood as the
primus inter pares, much like the way in which most of the world’s Orthodox currently view the Ecumenical Patriarch.
I explored the problems associated with private judgment and the receptionism theory in a post yesterday. What do you think of that?
On the other hand, I am also very skeptical about claims made by many Catholics (and I hear this claims coming mainly from laity who are not historians or theologians) that the papacy was understood as involving universal ordinary jurisdiction exercised in the way in which the current canons permit it to be exercised.
And you may be correct. The first millennium did not know the papacy of the second. But then, my elementary school teachers could not pick me out of a line-up, either. If the papacy did develop in a legitimate way, then we can’t look back at the Patristic writings and come to any conclusions based upon their failure to see the modern papacy that we are familiar with.
