St. John of Capistrano (1386-1456)
John left his position as governor of Perugiato become a Franciscan. He traveled through Italy after his ordination, preaching and performing miracles of healing, and assisting St. Bernardine of Siena in reforming the Order. He was employed as papal legate on numerous occasions, and was the leading spirit in the crusade against the Turks in Hungary where he led the left wing of the Christian army to victory at the battle of Belgrade.

Reflections from the Saints

If we have obtained the grace of God, none shall prevail against us, but we shall be stronger than all who oppose us.
