Ciszek, a native of Shenandoah and a son of St. Casimir Church, is a candidate for sainthood. In 1941 he was arrested for alleged espionage for the Vatican, imprisoned and then detained in the former Soviet Union for more than 20 years, during which he prayed, celebrated Divine Liturgy, heard confessions and otherwise ministered to the faithful despite risk to his own safety.

He was finally released in 1963 in exchange for two Russian spies. He then worked at the John XXIII Center at Fordham University in New York. Father Ciszek died on Dec. 8, 1984. Ciszek’s cause for canonization began in the Ruthenian Byzantine Catholic Eparchy of Passaic and was later transferred to the Diocese of Allentown. It is now at the Vatican in Rome.
