The letter H is the sponsor of today’s post. Hence, our saint for today is St. and Pope Hilarius (no joke about that name):
Pope Hilarius (died 28 February 468) was Pope from 19 November 461 to his death in 468.
Hilarius was born in Sardinia. As archdeacon under Pope Leo I, he fought vigorously for the rights of the Roman See and vigorously opposed the condemnation of Flavian of Constantinople at the Second Council of Ephesus in 449 to settle the question of Eutyches. According to a letter to the Empress Pulcheria collected among the letters of Leo I, Hilarius apologized for not delivering to her the pope’s letter after the synod, but owing to Dioscurus of Alexandria, who tried to hinder his going either to Rome or to Constantinople, he had great difficulty in making his escape in order to bring to the pontiff the news of the result of the council.
Hilarius erected several churches and other buildings in Rome, for which the Liber Pontificalis, the main source for information about Hilarius, praises him. Two oratories in the baptistery of the Lateran, one in honor of St. John the Baptist, the other of St. John the Apostle, to whom he attributed his safe escape from the Council of Ephesus, are due to him, thus satisfying the question as to which Saints John the Lateran had been dedicated. He also erected a chapel of the Holy Cross in the baptistery, convents, two public baths, and libraries near the Basilica of St. Lawrence outside the Walls, in which church he was buried.
His feast day is celebrated on 17 November or 28 February.
