He was one of the great apostles of the Holy Name of Jesus. Three other great apostles of the Holy Name of Jesus are: Saint Bernard of Clairvaux, Saint Bernardine of Siena and Saint Ignatius of Loyola. Saint John of Capistrano was a Franciscan. It was through his devotion to the Holy Name of Jesus that the Catholics were able to beat the Turks in the Battle of Belgrade in 1456. Led by Saint John of Capistrano, every soldier in the Catholic army kept saying, “Jesus! Jesus!” as he fought. The relics of Saint John of Capistrano were thrown into the River Danube by the Lutherans in the sixteenth century, but the Catholics were able to recover them.
