St. Cyril, the Patriarch of Alexandria, was dealing with Nestorius at the time and some of his sentiments may have been directed to him.
Sure, but if you read his homilies on Luke, it’s pretty clear that they are lessons that apply to everybody.
If St. Cyril agrees with you, why did he appeal to Pope Celestine for guidance on the Nestorian controversy?
What exactly are you referring to here? If you are referring to Ephesus, it is important to remember that Nestorius had appealed to Pope Celestine himself, hoping that Celestine would take his side against St. Cyril in their ongoing conflict. In that context, doesn’t it make sense that St. Cyril would also go to Celestine, hoping for the opposite outcome? You must remember that these were three
patriarchs in dispute; it was not as though St. Cyril was a layperson, appealing to some imagined “Papal authority” that he himself would not have also had (and, after all, he presided over the council in question). In fact, if we read the letter of the council sent to the Roman Pope (who, of course, did not attend), which we can do
here, there is by no means a clear sense of the Roman Pope being any sort of final, deciding authority over such matters. The letter makes the point that the condemnation of Nestorius and those in his camp is arrived at by consensus, and the Council wishes to inform the Roman Pope of that the goings on of the synod and to add HH’s consensus to it: “When there had been read in the holy Synod what had been done touching the deposition of the most irreligious Pelagiansand Coelestines, of Coelestius, and Pelagius,and Julian, and Praesidius, and Florus, and Marcellian, and Orontius, and those inclined to like errors, we also deemed it right that the determinations of your holiness concerning them should stand strong and firm. And we all were of the same mind, holding them deposed. And that you may know in full all things that have been done, we have sent you a copy of the Acts, and of the subscriptions of the Synod. We pray that you, dearly beloved and most longed for, may be strong and mindful of us in the Lord.”
Why did he wait for the Pope’s decision before going to Constant(name removed by moderator)ole?
Again, what exactly are you referring to? At the time of the Council of Constantinople, St. Cyril was between 3 and 6 years old (born c.375-378; council called 381)
Why, at the Council, did he rely on the Pope’s authority and not his own? Those are questions worth considering.
Again, what are you talking about?
