Blessed Alfons Maria Mazurek, also known as Alfons Maria of the Holy Spirit (†1944) was a Polish Discalced Carmelite friar and priest venerated as one of the 108 Martyrs of World War II. Mazurek was a professor and rector of the Carmelite seminary and director of the tertiaries at the monastery in Wadowice. In 1936, he became the first visitor of the Carmelite communities in Poland and wrote new statutes for the Order. He prepared for publication a breviary for Carmelite tertiaries and retreat texts written by the Carmelite Fr. Marcin Rubczyński. Separated from the friars and residents of Czerna, who had been forced to work on the town's fortifications, Mazurek was shot by an SS soldier on August 28, 1944. He was beatified by John Paul II on June 13, 1999 along with a group of other Polish martyrs of the Second World War. The relics of Blessed Alfonso are kept in the church of the Discalced Carmelites in Wadowice.
