well, the headline is false - only the part of the Orthodox church that bears allegiance to the Moscow Patriarch (who has whole heartedly given his blessing to Muscowy’s invasion of Ukraine) has been banned.
Seventy-two percent of the population avowed fidelity to an Eastern Orthodox Church: 54% of Ukrainians proclaimed adherence to the autocephalous Orthodox Church of Ukraine; 14% identified as Orthodox Christian without specifying a church affiliation; 4% associated with the Moscow Patriarchate.
So, only the 4% are affected. And that’s because the Moscow patriarch is tied at the hip to the invasion of Ukraine.
