Rome is showing off its divine protection exquisitely right now. Who else could survive the current pontificate?
Agreeing on the same date for Easter would be nice, but some Eastern Orthodox are not going to go along with a Catholic calendar.
Bart is an ecumenist and by Orthodox standards quite liberal. He presides over a see that has been driven to the brink of extinction by centuries of Islamic persecution and he is neither liked nor trusted by a majority of the other Patriarchs. He has repeatedly been rebuked by the monks of the Holy Mountain. So while he is the primus inter pares I would take anything you may hear about/from him with these facts in consideration.
Having a common date for Easter would be nice, but from a practical perspective it is not going to happen. The Orthodox Paschalion was codified at the First Ecumenical Council and cannot be changed except by another council. Even the scoundrel Meletius IV (a Freemason) who tried to foist the so called “Reformed Calendar” on the Church and created a schism that remains to this day, knew better than to touch the Paschalion.
