From the sermon Special Graces of the Immaculate Conception given on December 8, 2019
O Immaculate Virgin Mary, conceived without sin! Thou wert miraculously preserved from even the shadow of sin, because thou wert destined to become not only the Mother of God, but also the mother, the refuge, and the advocate of man; penetrated therefore, with the most lively confidence in thy never-failing intercession, we most humbly implore thee to obtain for us that angelic purity which was thy favorite virtue, that purity of heart which will attach us to God alone, and that purity of intention which will consecrate every thought, word, and action to His greater glory. Obtain also for us a constant spirit of prayer and self-denial, that we many recover by penance that innocence which we have lost by sin, and at length attain safety in that blessed abode of the saints, where nothing defiled can enter.
O Mary, conceived without sin, pray for us who have recourse to thee.
O Mary, Virgin, most prudent, Mother, most tender, pray for us.
Intercede for us with Jesus our Lord.
In thy conception, Holy Virgin, thou wast immaculate.
Pray for us to the Father Whose Son thou didst bring forth.
Amen.
