Pope Saint Sylvester surely was appointed by God to govern his holy church in the first years of her temporal prosperity and triumph over her persecuting enemies. His pontificate was one of the most important, crucial and eventful of all Popes.
Pope Saint Hyginus was bishop of Rome from about 138 to about 140. He was born in Athens, Greece at an unknown date. The Liber Pontificalis also relates that this pope organized the hierarchy and established the order of ecclesiastical precedence (Hic clerum composuit et distribuit gradus). Eusebius claims that Hyginus's pontificate lasted four years.
Pope Saint Telesphorus (ca. 125 - 138 AD) was a Greek who had been an anchorite. He ruled the Church in the time of Emperor Antoninus Pius. To St. Telesphorus are attributed some church practices which endure down to this day.
Blessed Pope Urban V was born Guillaume de Grimoard at Grisac in Languedoc, 1310. He always had a Benedictine spirit and even wore his monk’s habit as pope. His reign was blessed by his peacekeeping activity between the French and Italian kings, the founding of many universities, his zeal for the crusades and his decision to return the papacy to Rome and end the Avignon exile of the popes.
Pope Saint Celestine V reigned a mere five months. The primary objective of his pontificate was to reform clergy. He abdicated on 13 December 1294, the last pope to do so until Pope Benedict XVI.
Pope St. Pius X (1903-1914) Perhaps nowhere in the history of the Church is there a better example of a man possessed of so many of the saintly virtues—piety, charity, deep humility, pastoral zeal, and simplicity—than in Pope St. Pius X.
Pope Saint Pius V (1566-1572) was a Domincan. He called the Council of Trent, Excommunicated Elizabeth I of England for schism, was the patron Palestrina, and organized the Holy League for the defense against the Ottomans at the Battle of Lepanto.
Little is known of Pope Saint John I's life before he took office as pope, except that he was born in Tuscany. After a journey to Constantinople concerning Ariansism, he was arrested by Theordric, Arian king of the Ostrogoths. Worn out by his journey and probably starved, John died in prison soon after. Pope St. John I is honored as a martyr.
Pope Saint Cletus, the third Pope, governed the Roman Church from about 76 to about 88 during the reigns of the Emperor Vespasian and of Domitian.
