Irmos: O Lord, Fashioner of the vault of heaven and Creator of the Church: establish me in Thy love, O Summit of desire, confirmation of the faithful, Who alone lovest mankind.
Sessional hymn, in Tone III: Spec. Mel.: “Of the divine Faith…”—
Thou didst carefully set up the pillar of the Orthodoxy of the Church of Christ, O Leo most wise; and wielding it, the Church destroyeth the ungodly hosts and assemblies of the heretics.
Theotokion: Like a bride wast thou adorned with the beauties of virginity, O joyous Virgin Mother who knewest not wedlock; for thou hast far surpassed every creature, in that thou gavest birth to the Word, the Cause of all.
Replete with the divine grace of heaven, O father, thou didst set forth the dogmas of the Church, contending against all the blasphemies of the heretics, O Leo, champion of piety, who art most rich.
Glory…, Now & ever…: Theotokion—
Illumined with most splendid light, thou didst utter discourse on the ineffable and divine incarnation, setting forth the twofold Essence and twofold activity of the incarnate God.
Like a lion of righteousness thou didst cause audacity to cease, and didst confirm Orthodoxy by thy deeds, as thou didst hope. And thou preachest the doctrines of Truth and dost denounce the hidden works of deception. O venerable father, entreat Christ God, that He grant us great mercy.
Without separating Himself from the divine Essence, the one Lord remained God when He became man, taking on flesh in thy womb; and even after thou gavest birth, He preserved thee, His Mother, a Virgin, immaculate as thou wast before giving birth. Entreat Him earnestly, that He grant us great mercy.
Stavrotheotokion—
The unblemished ewe-lamb of the Word, the undefiled Virgin Mother, beholding Him Who sprung forth from her without pain suspended upon the Cross, cried out, lamenting maternally: “Woe is me, O my Child! How is it that Thou sufferest willingly, desiring to deliver man from the indignity of the passions?”
