Metropolitan Seraphim of Piraeus's volte face ably described by eish, April 24, 2024 :
"Metropolitan Seraphim of Piraeus is one of the only anti-ecumenists* in the Greek hierarchy. He is almost certainly the most vocal anti-ecumenist bishop in World Orthodoxy, at least from what I have heard and considering that there are also multiple language barriers. Fr. Peter [Heers] knows Metropolitan Seraphim personally and while he was usually not keen to talk about which bishop he was under, I remember talk either of him having been under Met. Seraphim or perhaps there was an element of speculation to people saying that.
Then with the 2020 lesson when we all learned something about who our real friends were, the metropolitan went completely nuts with his covidism. He is infamous for excommunicating anyone who does not take the clot shot.
Fr. Peter has himself even spoken of this change in his videos and called the metropolitan out for it.Bishops in World Orthodoxy are almost always ecumenists, meaning that when Met. Seraphim fell into covidism--or perhaps just showed his true colours under it, who knows what goes on in his mind--that really left Fr. Peter with only one bishop he could point to as his confessing orthodox hierarchy.
In being publicly against both [<ecumenism and vaccinations], Met. Neophytos stands alone and thus there are no other bishops who publicly and openly proclaim views like those of Fr. Peter.
*If we interpret anti-ecumenism to mean here conservative ecumenism, or a minimalist ecumenism in that they concelebrate with and commemorate ecumenists and other hierarchs who call themselves "orthodox", but not those heretics who do not claim to be Eastern Orthodox."
