Just a few months ago, I suddenly discovered on the Internet the full list of members of the so-called "Union of Russian People" (also known as "The Black Hundred") - an organization with blatantly Anti-Semitic (or, rather, Judophobic) agenda, which was active in the 1890-s - 1900-s and which if not directly organized, then at least inspired a long series of bloody Jewish "pogroms." The list, to my utter astonishment, has names of many Russian Orthodox clergymen, including recently canonized Neo-Martyrs, like, for example, Archbishop Veniamin of St. Petersburg.
So, what should we say - that these people were not saints, if they held Judophobic views? Perhaps no, we should not say that. They were not perfect, but no one is perfect except God. Something that they did for our faith, for our Church was decided by the Church to be worthy of counting them as saints, even though they made mistakes or hung out with a wrong crowd.
