Armenian Apostolic Holy Church The Mother See of Holy Etchmiadzin

At the Opening of the Doors service, the clergymen symbolically ask for the Lord's mercy. Psalms, prayers, and hymns are sung in front of the closed altar during the service. The mysterious door-opening ceremony performed in the evening of Palm Sunday completes the celebration performed in the morning, during which also, after a long pause, the curtains of the altars are opened again in the churches.
