The Our Father (“Pater Noster“) prayed by Pope John XXIII

Pope John XXIII (born Angelo Giuseppi Roncalli) was pope from 1958 to 1963. As the head of the Catholic Church, he was known for revising the Roman Missal (or guidelines to how to say the mass among Latin Rite Catholics) in 1962, and calling to order the Second Vatican Ecumenical Council that same year. He unfortunately died in 1963, a year after the council started, and the rest of the council was led by his successor, Pope Paul VI. His beatification process was started in 1965 under that same pope, and he was declared a saint by Pope Francis in April of 2014, along with a another former pope, Pope John Paul II (r. 1978-2005). He is considered the patron saint of the Second Vatican Ecumenical Council, of Christian unity, of the Patriarchy of Venice, and of Papal delegates. Here is a video taken from his inaugural mass in 1958 in which he recited the Our Father, or Pater Noster in Latin.
