From the homily of St. Cyril of Alexandria preached at the Council of Ephesus
Hail Mary, Mother of God, august treasury of the whole world, unquenchable torch, crown of virginity, scepter of orthodoxy, temple indestructible, and place of the uncontainable, mother and virgin. Through you is named blessed in the holy gospel He who comes in the name of the Lord. Hail Mary! You contained the uncontainable in your holy virginal womb. Through you the Trinity is glorified; through you is the cross named precious, and adored throughout the whole world; through you heaven exults; through you angels and archangels rejoice; through you demons are put to flight; through you the devil, the tempter, fell from heaven; through you the fallen creature is taken up to heaven; through you the whole created world, gripped in the madness of idolatry, come to a recognition of the truth; through you comes about holy baptism for believers; through you the oil of gladness; through you churches have been founded through the whole world; through you nations are led to repentance.
What need is there to speak at length? Through you the only Son of God shone His light for those who sat in darkness and in the shadow of death; through you prophets foretold what was to come; through you apostles preach salvation to the nations; through you the dead are raised to life; through you kings reign, through the Holy Trinity.
What man can sing adequately the praise of Mary? She is both virgin and mother! The wonder astounds me. Shall the Builder be forbidden to inhabit the temple He has built? Shall He be despised who chose His handmaid for His mother?
See then, all things rejoice. May it be ours to fear and bow before the unity of the Trinity, to worship and tremble in awe before the indivisible Trinity, as we sing praises of the ever-virgin Mary, that is the holy Church, and of her Son and immaculate spouse; for to Him is glory for ever and ever. Amen.
