The Ascension of the Lord — Hambartsum — was established in Armenia in 4-5 centuries and is celebrated on the fortieth day after Easter.
It is based on the gospel narrative of how the risen Jesus Christ called the apostles to the Mount of Olives ( Oilseeds ) near Jerusalem and blessed them with a worldwide sermon: « Go, teach all nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to keep everything that I have commanded you; and behold, I am with you all the days until the end of the age of ».
With these words, He began to move away, ascended and disappeared into the cloud, and « he sent the right hand of God ». While the apostles looked at heaven, two angels appeared and spoke of the ascension of Christ, who in due time would come again for the Judgment of humanity and the affirmation of the kingdom of heaven: « He will come in the same way, as you saw Him ascending to heaven ».
Jesus warned the apostles about the signs that would precede this phenomenon: «...The sun will fade, and the moon will not give its light, and the stars will fall from heaven, and the powers of heaven will be shaken. Then the sign of the Son of Man in heaven will appear; and then all the tribes of the earth will be kindled and see the son of Man coming in the clouds of heaven with great power and glory... Nobody knows about the day and hour, nor the Angels of heaven, but only My Father alone ».
