Sunday of Orthodoxy

On March 11, 843, icon veneration was officially reinstated in the Hagia Sophia Cathedral in Constantinople. From the article:

"Sunday of Orthodoxy
Theme
The Sunday of Orthodoxy is the first Sunday of Great Lent. 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, this Sunday has been commemorated as the “Triumph of Orthodoxy.”

Story
The Seventh Ecumenical Council dealt predominantly with the controversy regarding icons and their place in Orthodox worship. It was convened in Nicaea in 787 by Empress Irene at the request of Tarasios, Patriarch of Constantinople. The Council was attended by 367 bishops.

The Council decided on a doctrine by which icons should be venerated but not worshiped. In answering the Empress’ invitation to the Council, Pope Hadrian replied with a letter in which he also held the position of extending veneration to icons but not worship, the last befitting only God.

Observance of the Week
At the conclusion of the Divine Liturgy, a service is conducted in commemoration of the affirmations of the Seventh Ecumenical Council in 787 and the restoration of the use of icons in 843. Orthodox faithful carry icons in a procession, followed by a reading of excerpts from the Affirmation of Faith of the Seventh Ecumenical Council and the singing of the Great Prokeimenon.

It is becoming a common practice that the Procession of the Icons is conducted as part of a Pan-Orthodox Vespers service on the evening of the Sunday of Orthodoxy. This is a service when Orthodox Christians of the various jurisdictions in America come together for worship and in a united affirmation of the Truth of the Orthodox Faith.

The Icon
The icon of the Sunday of Orthodoxy commemorates the “restoration” of icons in the churches and to their use in Orthodox worship. The focal point of the icon is an icon itself, the Virgin Hodegetria, a popular depiction of the Theotokos as “Directress,” or literally “She who shows the way to God.” The icon is carried by two angels.

To the left of the icon is the Empress Theodora and her son Michael III. To the right of the icon are the Patriarchs Methodios and Tarasios. The icon is surrounded by numerous saints who struggled against the Iconoclastic heresy.

The icon also represents the triumphant procession that was made on Sunday, March 11, 843, from the Church of the Theotokos in Blachernai to Hagia Sophia, where a Liturgy was celebrated to mark the restoration of icons."
