Each evening after Compline and the Salve Regina, the Sisters, still in procession, chant the O Lumen hymn, a tribute to heroic virtues of St. Dominic, who is the Light of the Church, teacher of Truth, rose of patience, ivory of chastity. You freely poured forth the waters of wisdom. Preacher of grace, unite us with the blessed. Humbly we implore Father Dominic for the grace to speak the Truth to all whom we have the privilege to minister to. We also ask for gift of final perseverance and to be numbered among the saints in glory.
