The Works of St. Optatus
St Optatus
66 THE CATHEDRA
The Cathedra?- we must see who was the first to sit on the Cathedra, and where he sat. If you do not know this, learn. If you do know, blush. Ignorance cannot be attributed to you it follows that you know. For one who knows, to err is sin. Those who do not know may sometimes be pardoned. You cannot then deny that you do know that upon Peter first in the City of Rome was bestowed the Episcopal Cathedra on which sat Peter, the Head of all the Apostles (for which reason he was called Cephas ),
1 St. Cyprian was the first Father to use the term Cathedra (Chair). He applied it (as a word in common use at the time) to the See of Rome which he termed the Cathedra Petri. Parmenian, evidently, had claimed the Cathedra, stating that it belonged to him through the Angelus or Bishop (in other words We have valid Orders, and therefore we are in the Church ). St. Optatus replies to this in the text by making direct appeal to Rome. No man can possess a Cathedra, argues Optatus, who is not in communion with the one Cathedra, which, in all but successive sentences, he calls una Cathedra, singularis Cathedra and Cathedra unica.
THE CATHEDRA PETRI 67
that, in this one Cathedra, unity should be preserved by all,
1 lest the other Apostles might claim each for himself separate Cathedras, so that he who should set up a second Cathedra against the unique Cathedra 2 would already be a schismatic and a sinner.
bear in mind that St. Cyprian was at this time the great authority
This perfectly plain doctrine of St. Optatus was never once challenged amongst Christians (the Albigenses were Manichees rather than Christians) until the days of Hus and Wycliffe, some nine hundred years later. We know that the work of St. Optatus was the great authority and handbook ofSt. Augustine in his arguments against the Donatists. He constantly echoes the teaching of St. Optatus, concerning the Chair of Peter, and, in his controversy with the Donatists, applied the famous promise Upon this Rock I will build my Church to this Holy See. Sedes Petri . . . ipsa est Petra (Ps. con. Donat. St. xiv).
