Are you assuming because he’s [Hosius] from ‘Spain’ he’s western, therefore under the pope?
No, I’m saying he’s under the pope based on the witness of Greek historian Gelasius that Hosius 'held the place of Sylvester of Rome, together with the Roman presbyters Vito and Vincentius."[Migne, Patrologia Graeca, 85:1229]. Granted, Gelasius wrote his history 150 years after the council. But he claimed to have the official Acts of the Council, which have subsequently been almost completely lost.
Is there any written documentation of the period to support that suggests that Hosius presided on behalf of the Emperor, or is the recent scholarly conjecture based solely on their prior relationship?
That’s the problem. You’re saying it’s his right alone, but often ignored
I’m saying it’s
logically the role of the pope to convene a council, because it’s a call to the church to solemnly use the power of the keys to bind and loose in an ecclesial way. It is precisely the function of the successor of Peter to do this. It should have nothing to do with emperors.
The vagaries of history are otherwise, and emperors have obviously been involved.
it’s you using an argument from silence – without recognising it as such. It’s making a claim to the pope having power, but showing where that was ignored; thus I would question you assumption he had that power.
As we don’t have most of the acts of the council, I’m afraid we both in large measure have to be content with silence insofar as 4th century sources go. But in the 5th century we have Gelasius’ witness re: Pope Sylvester’s presidency in the person of Hosius. We have the seventh century Constantinople III assuring us that the Pope did indeed (with Constantine) summon I Nicea.
We have the Byzantine liturgy I cited above about Pope Sylvester’s victory at Nicea. And, to add to that, from the Byzantine office of St. Sylvester a phrase that implies the pope’s presidency: ‘Thou hast shown thyself the supreme one of the Sacred Council, O initiator into the sacred mysteries, and hast illustrated the Throne of the Supreme One of the Disciples.’ (Luke Rivington, The Primitive Church and the See of Peter). The phrase ‘supreme one of the Sacred Council’ is striking.
This is all, admittedly, from a later tradition. But given the absence of contemporary witness to Nicea, what reason is there to doubt these later traditions?
Are you now saying that the signature of the legates means that the pope doesn’t have to then confirm it?
I’m not. I’m suggesting that, though the bishop of Rome’s essential role was always recognized, that its constituent parts still handn’t been fully spelled out. So it seems possible that the signature of the legates (and, I believe, the president) at the top of the list, with ‘in the name of the Church of Rome’ after the names of Vicentius and Vitus, might have led some to believe that Sylvester had fully adopted the council.
To conclude, I think there’s ample evidence, even in the first two councils, that the Petrine function is essential to an ecumenical council, which is a convocation of the successor of Peter with the successors of the apostles to solemnly loose and bind the Church.
It’s fine, praiseworthy even, to inspect the minutia of various councils to examine precisely the pope’s role in each, whether he convened it, whether he presided over it. But although these functions are proper to the pope, they do absolutely nothing to affect the validity of a council, given the pope’s confirmation.
