The Aposticha from the Octoechos; and Glory..., in Tone IV —

This day let us, the assemblies of the Orthodox, faithfully acting in accordance with piety, celebrate the prayerful memory of the God-bearing fathers who assembled from throughout all the world in the splendid city of Nicæa; for with pious mind they rejected the godless dogma of the dreadful Arius, and in council cast him out of the Church universal, and in their Symbol of Faith have clearly taught all to confess the Son of God to be consubstantial, equally everlasting, and existing from before the ages, setting this forth with precision and piety. Wherefore, following their divine dogmas and believing them with certainty, we worship the Trinity One in essence — the Son and the Holy Spirit together with the Father — in one Godhead.

Now & ever...: Theotokion, in the same tone —

At the Blessing of the Loaves, the troparion “Virgin Theotokos, rejoice...,” twice; and that of the fathers, once, in Tone VIII —

Mercifully regard the supplications of thy servants, O all-immaculate one, quelling the demons’ cruel uprisings against us, delivering us from every sorrow; for thee alone have we as a steadfast and sure confirmation, and we have acquired thine intercessions; let not us that call upon thee be put to shame, O Mistress. Haste thou to answer the entreaty of those who cry out to thee with faith: Rejoice, thou help, joy and protection of all, and salvation of our souls!

Now & ever…, Theotokion, or this Stavrotheotokion —

Where thy grace doth cast its shadow, O archangel, thence is the power of the devil driven away; for the fallen morning-star cannot bear the sight of thy light. Wherefore, we entreat thee: Quench thou the fiery darts which he doth loose at us, delivering us from his temptations by thy mediation, O right laudable Gabriel, thou supreme commander.

Most glorious art Thou, O Christ our God, Who hast established our fathers upon the earth as beacons, and hast thereby guided us all to the true Faith! O greatly Compassionate One, glory be to Thee!

Of old, the Virgin Mother, the most blessed Maiden, beholding the Lamb, her Son, lifted up upon the Cross, cried out, weeping: “Woe is me, O my Son! How is it that Thou diest Who art in essence God immortal?”
