Sunday of Orthodoxy

The Sunday of Orthodoxy is the first Sunday of Great Lent, and it commemorates a specific historical event: the final restoration of the holy icons in 843, ending more than a century of the iconoclast controversy in the Byzantine Empire, during which the veneration of images was twice condemned and images destroyed. The restoration under the empress Theodora is remembered as the "Triumph of Orthodoxy", and the day celebrates not icons alone but the vindication of right belief as such.

The theology at stake had been settled in principle at the Second Council of Nicaea in 787, which taught that the honour paid to an image passes to the person it represents, and that the veneration of icons follows from the reality of the Incarnation: because God took visible flesh, he can be depicted. On this Sunday a procession carries icons through the church, and the Synodikon of Orthodoxy is read, proclaiming "eternal memory" to the defenders of the faith and, historically, anathemas against its opponents. The feast thus turns a hard-won doctrinal outcome into an annual affirmation of what the Orthodox understand their faith to be.

In countries such as the United States, where multiple self-governing Orthodox jurisdictions, Greek, Russian, Antiochian, Serbian and others, operate in the same cities without a single unified local hierarchy, the Sunday of Orthodoxy has become, since the later twentieth century, a customary occasion for joint pan-Orthodox vespers services bringing clergy and parishioners from these separate jurisdictions together in one place, a modern practical use of a feast originally about the restoration of icons to also perform and visibly demonstrate a shared Orthodox identity that the actual administrative structure of Orthodoxy in these countries does not otherwise make obvious to onlookers.

This layering of a modern unity gesture onto an ancient doctrinal commemoration sits comfortably with the feast's own original content, since the Synodikon read on the day already frames Orthodoxy as a single shared confession defended across time by many local churches acting together, so that a joint modern service drawing together jurisdictions with separate administrative histories but a common faith extends, in a very practical present-day form, the same claim to unity in doctrine the original 843 restoration was itself understood to vindicate.
