BONIFACE I (Saint) Pope. (October 25) (5th century) A Roman priest of saintly life, elected Pope (A.D. 418), in succession to Saint Zozimus, notwithstanding his reluctance. Though pre-eminently “a man of peace,” he vindicated bravely and successfully the rights of the Holy See against the Anti-Pope Eulalius, and against the pretensions of the Patriarchs of Constantinople. He ordered the singing of the Gloria, in excelsis on Maundy-Thursday, and regulated several points of Church discipline. He passed away towards the close of the year 423, and was buried in an Oratory of Saint Felicitas, which with many other sacred buildings he had restored and embellished.
