A priest of the Russian Orthodox Church bravely answers: Excommunicate them! In his own words, he begins by saying,
Black Lives Matter is a terrorist, Marxist organization which promotes abortion and homosexuality. This wicked group was founded by lesbian feminists, and has received tens of millions of dollars in funding from the atheist George Soros.
To support Black Lives Matter is to turn away from Christ, and rejection of Christ makes a person unworthy to take Holy Communion.
Therefore, as a priest in the Orthodox Church, it is my duty to ban all members of Black Lives Matter from receiving Communion. I will not desecrate the precious Body and Blood of Christ, by allowing it to touch the unclean lips of those who are members of that satanic organization.
If you are willing to renounce that organization, and to cancel your membership in that group, then you can come to confession. You can be absolved of the sin you committed by joining Black Lives Matter. After that, you can take Holy Communion. After — not before. Until you demonstrate repentance, you will not receive the Eucharist.
He goes on to show the Marxist, baby-slaughtering, etc. ties of BLM in the rest of the article.
Now, with that in mind, consider the stance of Archbishop Elpidophoros, the head bishop of the Greek Orthodox Church in America, toward BLM:
On June 3, Archbishop Elpidophoros, the head of the Patriarchate of Constantinople’s Greek Orthodox Archdiocese of America, in the wake of the death of George Floyd.
His participation garnered much praise, as well as much criticism because of the pro-abortion and pro-LGBT politics of Black Lives Matter and because the event was held in the midst of the coronavirus pandemic during which the Archbishop himself had closed his churches.
The day before he marched, police officer Shay Mikalonis, a member of the St. John the Baptist Greek Orthodox Church in Las Vegas, was during a Black Lives Matter protest and is currently on life support. Abp. Elpidophoros has also come under heavy criticism for making no public statement about Mikalonis and for joining with BLM after this incident.
. . .
The future does not look too bright for the GOA churches in the States with Archbishop Elpidophoros at their head.
Holy Ælfred the Great, King of England, South Patron, pray for us sinners at the Souð, unworthy though we are!
Anathema to the Union!
