Spin? There is no need to spin anything. St Leo the Great speaks of St Peter to convey unity of faith. After all, St Peter founded the See of Antioch first. All bishops speak through St Peter. All bishops speak through all the Apostles who derive their authority from Christ Himself. St Leo the Great’s writings are not proof of some type of doctrine of supremacy and/or infallibility.
Often cited as a proof of Papal Supremacy is the
Tome of Leo a letter sent by
Pope Leo to the Second Ecumenical Council. Part of it seems to some to suggest that Leo speaks with the authority of Peter.
“After reading of the forgoing epistle (Pope Leo’s), the most reverend bishops cried out: “This is the faith of the fathers, this is the faith of the Apostles. So we all believe, thus the orthodox believe. Anathema to him who does not thus believe. Peter has spoken thus through Leo. So taught the Apostles. Piously and truly did Leo teach, so taught Cyril.
Everlasting be the memory of Cyril. Leo and Cyril taught the same thing, anathema to him who does not so believe. This is the true faith. Those of us who are orthodox thus believe.”
However it is not just Leo’s teaching that is the teaching of the Apostle, but
Cyril’s teaching as well. Both teach as Peter.
At the Third Ecumenical Council
Pope Celestine and Cyril were compared to Paul!
“And all the most reverend bishops at the same time cried out. This is a just judgment. To Cœlestine, a new Paul! To Cyril a new Paul! To Cœlestine the guardian of the faith! To Cœlestine of one mind with the synod! To Cœlestine the whole Synod offers its thanks! One Cœlestine! One Cyril! One faith of the Synod! One faith of the world!”
In that context then the approval of the
Tome is simply to state a unity of faith, not only of the Pope but other churchmen as well. Leo and Cyril teach as Peter. Celestine and Cyril teach as Paul.
