Lent was in origin the time of final preparation for candidates for baptism at the Easter Vigil, and this is reflected in the readings at the Liturgy, today and on all the Sundays of Lent. But that basic theme came to be subordinated to later themes, which dominated the hymnography of each Sunday. The dominant theme of this Sunday since 843 has been that of the victory of the icons. In that year the iconoclastic controversy, which had raged on and off since 726, was finally laid to rest, and icons and their veneration were restored on the first Sunday in Lent. Ever since, that Sunday been commemorated as the "triumph of Orthodoxy."
Orthodox teaching about icons was defined at the Seventh Ecumenical Council of 787, which brought to an end the first phase of the attempt to suppress icons. That teaching was finally re-established in 843, and it is embodied in the texts sung on this Sunday.
Inspired by your Spirit, Lord, the prophets foretold your birth as a child incarnate of the Virgin. Nothing can contain or hold you; before the morning star you shone forth eternally from the spiritual womb of the Father. Yet you were to become like us and be seen by those on earth. At the prayers of those your prophets in your mercy reckon us fit to see your light, for we praise your resurrection, holy and beyond speech. Infinite, Lord, as divine, in the last times you willed to become incarnate and so finite; for when you took on flesh you made all its properties your own. So we depict the form of your outward appearance and pay it relative respect, and so are moved to love you; and through it we receive the grace of healing, following the divine traditions of the apostles.
The grace of truth has shone out, the things once foreshadowed now are revealed in perfection. See, the Church is decked with the embodied image of Christ, as with beauty not of this world, fulfilling the tent of witness, holding fast the Orthodox faith. For if we cling to the icon of him whom we worship, we shall not go astray. May those who do not so believe be covered with shame. For the image of him who became human is our glory: we venerate it, but do not worship it as God. Kissing it, we who believe cry out: O God, save your people, and bless your heritage.
We have moved forward from unbelief to true faith, and have been enlightened by the light of knowledge. Let us then clap our hands like the psalmist, and offer praise and thanksgiving to God. And let us honor and venerate the holy icons of Christ, of his most pure Mother, and of all the saints, depicted on walls, panels and sacred vessels, setting aside the unbelievers' ungodly teaching. For the veneration given to the icon passes over, as Basil says, to its prototype. At the intercession of your spotless Mother, O Christ, and of all the saints, we pray you to grant us your great mercy. We venerate your icon, good Lord, asking forgiveness of our sins, O Christ our God. For you freely willed in the flesh to ascend the cross, to rescue from slavery to the enemy those whom you had formed. So we cry to you with thanksgiving: You have filled all things with joy, our Savior, by coming to save the world.
from Vespers
The name of this Sunday reflects the great significance which icons possess for the Orthodox Church. They are not optional devotional extras, but an integral part of Orthodox faith and devotion. They are held to be a necessary consequence of Christian faith in the incarnation of the Word of God, the Second Person of the Trinity, in Jesus Christ. They have a sacramental character, making present to the believer the person or event depicted on them. So the interior of Orthodox churches is often covered with icons painted on walls and domed roofs, and there is always an icon screen, or iconostasis, separating the sanctuary from the nave, often with several rows of icons. No Orthodox home is complete without an icon corner, where the family prays.
Icons are venerated by burning lamps and candles in front of them, by the use of incense and by kissing. But there is a clear doctrinal distinction between the veneration paid to icons and the worship due to God. The former is not only relative, it is in fact paid to the person represented by the icon. This distinction safeguards the veneration of icons from any charge of idolatry.
Although the theme of the victory of the icons is a secondary one on this Sunday, by its emphasis on the incarnation it points us to the basic Christian truth that the one whose death and resurrection we celebrate at Easter was none other than the Word of God who became human in Jesus Christ.
