Annually, 14 weeks or 98 days after Easter Sunday, the Armenian Church celebrates the Feast of the Transfiguration of Christ (arm. Այլակերպութիւն Տեառն մերոյ Հիսուսի Քրիստոսի). "Vardavar" (arm. Վարդավառ) called. This festival, which is one of the five high festivals of the Armenian Church, combines, like many other church festivals, the religious and the popular.
In the Christian sense, this festival commemorates an important event in the life of our Lord (cf Matthew 17:1-8; Mark 9:1-7; Luke 9:29-36 such as 2 Peter 1:17-18). This event takes place in the final stage of the Lord's earthly life. Before this event, Christ had spoken to his disciples about his impending death, which left his disciples in despair and uncertainty. Jesus' announcements were very pessimistic. The disciples could not believe their ears: "God forbid that, Lord! This must not happen to you" (Matthew 16:22). But the Lord announced a thorny path for them too: "Whoever wants to be my disciple must deny themselves, take up their cross and follow me" (Matthew 16:24). Certainly the disciples were in great distress. And a week after this conversation, the glorious and wonderful event of the Transfiguration of the Lord took place on the top of Mount Tabor.
The evangelist Matthew reports: “Six days later Jesus took Peter, James, and his brother John and led them up a high mountain. And he was changed before their eyes; his face shone like the sun, and his clothes became blindingly white like the light. …A luminous cloud cast its shadow on them, and out of the cloud a voice cried: This is my beloved son, in whom I have found delight; you should listen to him"( Matthew 17:1-2:5). With this last sentence, Christ's three-year ministry on earth began with his baptism in the Jordan (cf Matthew 3:17). This phrase is repeated at his transfiguration, thus affirming the divine power and glory of the Lord. And the disciples were witnesses of this glorious and wonderful event and "They saw him in all his majesty" (Luke 9:32) and announced it.
For the Vardavar high festival, the hymn (charakan) "You who were glorified on the mountain and showed your divine power" sung. The hymn was most likely written by St. Movses Chorenatzi in the 5th century.
 The evangelists do not mention the name of the mountain, but in early Christianity it was widely believed that it happened on Mount Tabor. Peter names him "Sacred mountain".
