From Dom Guéranger's The Liturgical Year.
Rome honours today one of her own illustrious sons Chrysogonus, who gave his life for Christ at Aquileia in the reign of Diocletian. His spendid church in the Trastevere, which possesses his venerable head, was first built at the very time of the triumph of the faith over idolatry. Chrysogonus instructed in that holy faith the blessed martyr Anastasia, whose memory is so touchingly united with that of our Saviour’s birth, the Aurora Mass on Christmas day having been from time immemorial celebrated in her church. The names of both Chrysogonus and his spiritual daughter are daily pronounced in the holy Sacrifice.
Prayer
Adesto, Domine, supplicationibus nostris: ut qui ex iniquitate nostra reos nos esse cogniscimus, beati Chrysogoni martyris tui intercessione liberemur. Per Dominum.
Attend, O Lord, to our supplications; that we who know ourselves to be guilty on account of our iniquities, may be delivered by the intercession of thy blessed martyr Chrysogonus. Through our Lord.
