Both clerics who declared anathema to the OCU do not belong to the Greek Church. This is reported by fanarion.blogspot.com with reference to the official response of the Metropolis of Piraeus on March 25, 2021.

One priest separated from the Church, now he is a schismatic.

And the other has been in the Russian Orthodox Church since January and has declared his desire to serve on the territory of Great Britain.
