Pope St John XXIII.
"Angelo Giuseppe Roncalli was born in the village of Sotto il Monte, near Bergamo, in 1881. At the age of 11 he entered the seminary at Bergamo and later pursued his studies at the Pontifical Seminary in Rome. He was ordained priest in 1904. He was secretary to the Bishop of Bergamo but from 1921 onwards he served the Holy See directly in various posts, both in Rome and in Bulgaria, Turkey and Greece, culminating as Apostolic Nuncio to France from 1944 until 1953, when he was created cardinal and made the Patriarch of Venice. He was elected Pope in 1958. He convoked the Roman Synod, instituted the revision of Canon Law, and called the Second Vatican Council, which opened on 11 October 1962. He died while the Council was still in session, on the evening of 3 June 1963." Today, 11 October, is the feast of Pope St John XXIII. Stained glass from Manila Cathedral, the Philippines.
