I don't know. This is the second paragraph of the article:
“Speaking exclusively with AsiaNews, Bartholomew says that together with Pope Francis we agreed to leave as a legacy to ourselves and our successors a gathering in Nicaea in 2025, to celebrate together, after 17 centuries , the first truly ecumenical synod, where the Creed was first promulgated’.”
“Ecumenical synod” sounds more like “ecumenical council” than “celebration.
Yes, but the “synod” mentioned there must refer to 325 not 2025, no? “Where the Creed was first promulgated”?
Admittedly, the phrase can bear both readings.
This would indeed be earth-shattering to both sides...I just have trouble believing that a new Ecumenical Council would be announced so casually.
