The five greatest feasts of the Armenian Church are the tabernacle feasts. These feasts are called tabernacle feast because special tents called tabernacles, were set up in the fields for their observance. Each feast is preceded by a period of fasting and followed by a day of remembrance of the dead.

According to the Gospels (Matt. 17:1-8, Mark 9:1-10, Luke 9:28-36), while Jesus was on Mount Tabor, Moses and the prophet Elijah appeared beside Jesus and all three were engulfed in heavenly light. This transfiguration was witnessed by the disciples Simon-Peter, James and John Zebedee, who erected tabernacles and were surrounded by a cloud and a voice told them, "This is my Son and I have chosen him. Listen to Him."
