ORTHODOX SUNDAY - ( Feast of the Triumph of Orthodoxy) The first Sunday of Lent which celebrates the restoration of the icons to the churches in 842. It is the triumph of Orthodoxy over iconoclasm and other heresies.

Each of the Sundays of Great Lent has its own special theme. The first Sunday is called the Feast of the Triumph of Orthodoxy. It is a historical feast commemorating the return of the icons to the churches in the year 843 after the heresy of iconoclasm was overcome.

The spiritual theme of the day is first of all the victory of the True Faith. "This is the victory that overcomes the world, our faith" ^{(1 Jn 5:4)}. Secondly, the icons of the saints bear witness that man, "created in the image and likeness of God" ^{(Gen 1:26)}, becomes holy and godlike through the purification of himself as God's living image.
