This news seems huge to me. And sorry if there’s a thread on this topic already. I didn’t find one at first.
I’m a revert. When “on the way out,” I had critically evaluated some of the language published by the earliest Church Fathers to see what they said about Roman primacy. I found that prior to about 200-250 AD (a range starting around the time when Tertullian become a Donatist and finally after the persecution from Emperor Decius), it looked as though the Church Fathers mostly said that the primacy of Rome was based on the deaths of both Peter and Paul there. After 250 AD or so, most of the Church Fathers said that the primacy of Rome was based on Matthew 16:16-18. That seemed to me a change from “Roman primacy” to “Petrine primacy,” and to me that made me doubt.
I also compared how the Popes who heard about Quartodecimanism (celebrating easter on 14th day of Nisan in the Hebrew calendar) affected that. For example, Pope Anicetus (c. 157-168) didn’t agree with Quartodecimanism, but agreed to disagree with Bishop St. Polycarp of Smyrna. Later, in 193 AD, during the papacy of Victor I, there was a synod in Rome (among other synods) about it, and Pope Victor sent a letter to the eastern churches telling them to stop. Bishop Polycrates of Ephesus who held a synod in Ephesus to reject what the Pope had written. Pope Victor was going to excommunicate Polycrates, but St. Irenaeus and others intervened with him to follow a more peaceful path. Eventually, a group of Quartodecimanist bishops got together to review their tradition, which they said they’d received from the Apostles, and urged the all the churches to celebrate Easter on the same day as the rest of the Church. At that time, it suggested to me that Anicetus was less of a “micromanager” as was Victor, which I argued at the time was a result of changing ecclesiology.
However, I have since realized that my former reading was – shall we say – somewhat cherry picked. For example, Pope Anicetus himself got into the disagreement with St. Polycarp only because Polycarp had come to Rome to visit him… that suggests that St. Polycarp viewed the Bishop of Rome as his superior among bishops. I’ve also read the Bible a lot more, and to me, it now it’s clear that St. Peter was the head of the Church. There’s also the first letter of Clement I, which suggests that the Roman bishop was also the head of the Church.
To me, I think it would be useful to talk through all this history with our Orthodox brothers and sisters. They are sure to have arguments lined up, but so do we. But fundamentally, we need to have better relationships with them. Love and truth are both needed.
