There is nothing in that article I disagree with as a Catholic.
I am still struck by the absence of condemnation of the distinctive doctrines of Catholicism in the Synodicon despite the later polemics on both sides, especially from ~1480 onwards to the time of Pius XII. It is like the same circumspect attitude taken by the Catholic Church regarding Greek practices of ecclesiastical divorce.
“It is like the same circumspect attitude taken by the Catholic Church regarding Greek practices of ecclesiastical divorce.”
The Greek practice with regard to divorce goes back to, at the most recent, the 5th century. I must say, however, that I can’t see any reason for Rome to be circumspect about our practices concerning ecclesiastical divorce. perhaps it has to do with the different understandings of the Mystery itself.
