Council of Constantinople (843)

The Council of Constantinople of 843 or the Synod of Constantinople of 843 was a local council (as opposed to an ecumenical council) of Christian bishops that was convened in Constantinople (modern-day Istanbul, Turkey) in AD 843 by the Byzantine regent Theodora to confirm iconophilism in the Church. This council is still celebrated on the first Sunday of Great Lent in the Eastern Orthodox Church, as presecribed by the council.
