The other night I saw a local news clip and it had a Russian Orthodox priest on asking for donations through Catholic Relief charities. I know this priest because his son went to grade school with my daughters. He ran a (tiny) Russian Orthodox church but also worked for the Catholic archdiocese, as did his wife. He was saying that the Russian church is helping the Ukrainians. I trust him.
