The Vigil of the Ascension is a II Class feast in its own right, and therefore outranks the III Class feast of St. Catherine of Siena, Virgin and now Doctor of the Church, which falls on 30 April. The good St. Catherine is one of the patronesses of all Europe.
St. Catherine, of the Order of St. Dominic, led a life of great penance. She received the stigmata, but at her urgent prayer they did not show externally. She died in 1380.
