April 30: ST. PIUS V, POPE
Michael Ghislieri (1504-1572), a Dominican, became Pope Pius V. His pontificate was one of the most glorious in the 16th century. He enforced the decrees of the Council of Trent, published the Roman Catechism, and revised the Missal and Breviary.
O God, who in your providence raised up Pope Saint Pius the Fifth in your Church that the faith might be safeguarded and more fitting worship be offered to you, grant, through his intercession, that we may participate in your mysteries with lively faith and fruitful charity. Through our Lord.
