Fr Ambrose:
So what of the other successors of Saint Peter - the Patriarchs of Antioch. Are they infallible by virtue of their petrine succession? If not, why not?
I am glad that you asked, Father. The answer is that Peter received not one commission but two (Mt 16:19 & 18:18). He was both a bishop (the epicsopal ministry) like any other and the head of the bishops (the papal ministry).
While it is clearly possible and even desirable that there should be many bishops, it defeats the very logic of the papal ministry to have more than one pope. Just as there can be only one viceroy in Israel (2Kgs 19:2), so there can be only one viceroy in the Kingdom of Heaven. It makes no more sense to have more than one viceroy than it would make to have more than one king in the kingdom.
As such, while Peter can leave behind many
episcopal successors, he can leave only one
papal successor. In point of historical fact, the one papal successor which he left behind was Linus in Rome, and as such the Roman Pontiff is the Vicar of Christ (that is to say, the viceroy in the Kingdom of Heaven), while the Patriarch of Antioch is not. As Jane Austen said in
Mansfeld Park, it could have all been different, but it was not.
The Pope’s infallibility, as Vatican I makes clear, derives from the Pope’s supreme authority. Because he can speak for the whole Church, and because the Church (by definition) cannot err, it must be the case that when the Pope
does speak for the whole Church, he will be preserved from error. Meanwhile, the Patriarch of Antioch cannot speak for the whole Church (in the way that the Roman Pontiff can), and as such he is not protected by the same charism of infallibility. This would probably be a good point at which to address the matter of Papal ratification of councils, but I am trying to listen to the Presidential debates right now, so that question will have to wait for another time. Good night all.
