The Sunday of Orthodoxy, observed on the first Sunday of Great Lent in Eastern Orthodox Christianity, commemorates the restoration of holy icons to churches in 843 AD, marking the end of the Byzantine Iconoclasm, which was a period of controversy and persecution over the veneration of religious images.  
This feast celebrates the “Triumph of Orthodoxy” over heresy, affirming the Orthodox belief that icons are not idols but windows to the divine, worthy of honor but not worship.  
The procession held during this day reenacts the historical event that established the feast. Following the death of the iconoclast Emperor Theophilos, his widow, Empress Theodora (acting as regent for their young son Michael III), along with Patriarch Methodios, convened a synod in Constantinople that officially restored the veneration of icons. 
On March 11, 843 (which fell on the first Sunday of Lent that year) a grand triumphal procession carried icons from the Church of the Theotokos in Blachernae to Hagia Sophia, symbolizing the victory of Orthodox doctrine.   
The synod decreed that this anniversary be perpetually observed annually on the first Sunday of Lent with such commemorations. 
In contemporary Orthodox practice, the procession typically occurs after Matins (Orthros) or the Divine Liturgy, where clergy and faithful carry icons around the church or to a designated spot.   It serves as a liturgical expression of faith, reinforcing the theological significance of icons while invoking prayers for the Church, civil authorities, and the departed.  This ritual is common in cathedrals, monasteries, and parishes worldwide, emphasizing communal participation in the ongoing defense of Orthodox tradition.
