From divinumofficium:

Oratio V. Dóminus vobíscum. R. Et cum spiritu tuo. Orémus. Deus, qui beatum Cyrillum Confessorem tuum atque Pontificem divinae maternitatis beatissimae Virginis Mariae assertorem invictum effecisti: concede, ipso intercedente; ut qui vere eam Genitricem Dei credimus, materna eiusdem protectione salvemur. Per eundem Dominum nostrum Iesum Christum filium tuum, qui tecum vivit et regnat in unitate Spiritus Sancti, Deus, per omnia saecula saeculorum. R. Amen. Orémus. Pro S. Apolloniae Virginis et Martyris Deus, qui inter caetera potentiae tuae miracula etiam in sexu fragili victoriam martyrii contulisti: concede propitius; ut qui beatae Apolloniae Virginis et Martyris tuae natalitia colimus, per eius ad te exempla gradiamur. Per Dominum nostrum Iesum Christum, Filium tuum: qui tecum vivit et regnat in unitate Spiritus Sancti Deus, per omnia saecula saeculorum. R. Amen.

Collect V. The Lord be with you. R. And with thy spirit. Let us pray. O God, Who made Cyril, Your Confessor and Bishop, an unconquerable champion of the most blessed Virgin Mary’s divine motherhood, grant that we who believe that she is truly the Mother of God may be saved by her motherly protection. Through the same Jesus Christ, thy Son, Our Lord, Who liveth and reigneth with thee in the unity of the Holy Ghost, God, world without end. R. Amen. Let us pray. For ST. APOLLONIA O God, Who among the other miracles of Your power have bestowed the victory of martyrdom even upon the weaker sex, graciously grant that we who commemorate the anniversary of the death of blessed Apollonia, Your Virgin and Martyr, may come to You by the path of her example. Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end. R. Amen.

From the Office of Matins:

Lectio 3 Cyríllus Alexandrínus, Theóphili epíscopi Alexandríni nepos, étiam adoléscens præcelléntis ingénii specímina dedit. Theóphilo vita functo, ad illíus Sedem evéctus, et factus forma gregis ex ánimo, óptimi pastóris glóriam adéptus est. Singuláre eius pro cathólicæ fídei incolumitáte stúdium enítuit contra Nestórium Constantinopolitánum epíscopum, asseréntem Iesum Christum ex María Vírgine hóminem tantum et non Deum natum, eíque divinitátem pro méritis esse collátam; cuius emendatiónem cum frustra tentásset, eum sancto Cælestíno Papæ denuntiávit. Huius Pontíficis delegáta auctoritáte, nonnúllis sessiónibus præfuit Concílii Ephesíni, in quo hæresis Nestoriána pénitus proscrípta est, damnátus Nestórius et a sua Sede deiéctus, ac dogma cathólicum de una in Christo eáque divína persóna, et divína gloriósæ Vírginis Maríæ maternitáte assértum. De sola fide sollícitus, et proptérea plura perpéssus, máximis pro Ecclésia Dei perfúnctus labóribus, plurimísque scriptis éditis, sancto fine quiévit, anno quadringentésimo quadragésimo quarto, episcopátus trigésimo secúndo. V. Tu autem, Dómine, miserére nobis. R. Deo grátias.

19 V. Grant, Lord, a blessing. Benediction. May He that is the Angels' King to that high realm His people bring. Amen. Reading 3 Cyril of Alexandria was the nephew of Theophilus, bishop of Alexandria, and even as a young man gave evidence of unusual brilliance. When Theophilus died, Cyril succeeded to his see and, "becoming from the heart a pattern to the flock," gained glory as the best of shepherds. He shone in a special way in his zeal for the integrity of the Catholic faith against Nestorius, the bishop of Constantinople, who asserted that Jesus Christ was born of the Virgin Mary was a man only and not as God, and that divinity had been added to Him for His merits. After trying in vain to persuade Nestorius of the truth, Cyril denounced him to pope St. Celestine. As the delegate of this pope he presided over many sessions of the Council of Ephesus. In the council the Nestorian heresy was completely condemned and Nestorius himself deposed from his see, while the Catholic doctrine was proclaimed that in Christ there is but one Person and that Person divine, and that the glorious Virgin Mary is the Mother of God. Solicitous only for the faith and, as a result, enduring many things, Cyril accomplished great works for God's Church and published many writings. Finally he died a holy death in the year 444, the thirty-second year of his episcopate. V. But thou, O Lord, have mercy upon us. R. Thanks be to God.
