Tomorrow is the Sunday of the Triumph of Orthodoxy, celebrated annually in the liturgical calendar of the Eastern Orthodox Church on the first Sunday of Great Lent. The Feast is kept in memory of the final defeat of Iconoclasm and the restoration of the icons to the churches by the decision of the Seventh Ecumenical Council.
The debate involved important issues: the character of Christ’s human nature, the Christian attitude towards matter, and the true meaning of Christian redemption. Therefore, the service commemorates the restoration of icons for use in churches and in the private devotional life of Christians. Icons are held by the Orthodox to be a necessary consequence of Christian faith in the Incarnation of the Word, Jesus Christ. Icons are considered by Orthodox Christians to have a sacramental character, making present to the believer the person or event depicted on them.
Orthodox theology makes a clear doctrinal distinction between the veneration (proskynesis) paid to icons and the worship (latria) which is due to God alone.
