Synodikon

The Synodikon is a document proclaiming the decisions of the Church's councils. The most important is the Synodikon of Orthodoxy — read on the First Sunday of Great Lent (the Sunday of the Triumph of Orthodoxy) — which proclaims all the definitions of the seven Ecumenical Councils, anathematizes all condemned heresies by name, and proclaims the eternal memory of all orthodox teachers. The Synodikon is the Church's annual reaffirmation of its entire theological tradition.
