January 5th: Dom Gueranger on the Vigil of the Epiphany. Commemoration of St. Telephorus

"This Pontiff began his reign in the year 127; and among his decrees, we find that of his prescribing the holy sacrifice of the Mass to be offered on Christmas Night, in order to honour the hour when our Saviour was born; he also ordered that the Angelic Hymn 'Gloria in excelsis' should be said, on most days at the beginning of Mass. This devotion of the holy Pope towards the great Mystery which we are now celebrating, renders his commemoration at this season of the year doubly dear to us. Telesphorus suffered a glorious martyrdom, as St. Ireneus expresses it, and was crowned with eternal glory in the year 138."
