The reading in the Office of Our Lady for the third Saturday of June is from a sermon of St Augustine:
O beata Maria, quis tibi digne valeat jura gratiarum ac laudum praeconia rependere, quae singulari tuo assensu mundo succurristi perdito? Quas tibi laudes fragilitas humani generis persolvat, quae solo tuo commercio recuperandi aditum invenit? Accipe itaque quascumque exiles, quascumque meritis tuis impares gratiarum actiones: et cum susceperis vota, culpas nostras orando excusa. Admitte nostras preces intra sacrarium exauditionis et reporta nobis antidotum reconciliationis.
Blessed Mary, who is able enough to thank and to praise thee, thou, who by once saying Be it unto me, hast arisen to help a lost world? What blessings shall weak man utter upon thee, thou, who, by thine own one treaty, hast given unto him to find the entrance into new life? Receive these far and random, these unworthy thanksgivings, and, since thou receivest our prayers, by thy prayers obtain pardon for our sins. Let our supplications come into thine hallowed presence, and give us in return the medicine for our healing.
R. Felix namque es, sacra Virgo Maria, et omni laude dignissima: * Quia ex te ortus est sol justitiae, * Christus Deus noster.
V. Ora pro populo, interveni pro clero, intercede pro devoto femineo sexu: sentiant omnes tuum juvamen, quicumque celebrant tuam sanctam commemorationem.
R. Quia ex te ortus est sol justitiae.
V. Gloria Patri
R. Christus Deus noster.
R. O holy Virgin Mary, happy indeed art thou, and right worthy of all praise * For out of thee rose the Sun of righteousness, even Christ our God.
V. Pray for the people, plead for the clergy, make intercession for all women vowed to God. Let all that are making this holy memorial of thee feel the might of thine assistance.
R. For out of thee rose the Sun of righteousness
V. Glory be...
R. Even Christ our God.
