This Sunday (June 6) is the Feast of Holy Etchmiadzin, the cathedral built by St. Gregory after his deliverance from the pit, to the specifications he saw in a vision, and on the place marked by the Lord with a golden hammer. This feast day commemorates the establishment of the Armenian Church and the end of paganism. Etchmiadzin is the oldest example of a four- pillar, cruciform church in Christian architecture. More than 1,700 years old, it is the oldest surviving Armenian Christian site. Relief sculptures on the exterior walls are some of the oldest examples of the Christian Armenian art of sculpting.
