The Ascension of Jesus is the Christian teaching found in the New Testament when the resurrected Jesus was taken up to heaven in his resurrected body,[Acts 1:9-11] in the presence of eleven of his apostles, occurring 40 days after the resurrection. In the biblical narrative, an angel tells the watching disciples that Jesus' second coming will take place in the same manner as his ascension.
The Ascension of Jesus is professed in the Nicene Creed and in the Apostles' Creed. The Ascension implies Jesus' humanity being taken into heaven. The Feast of the Ascension, celebrated 40 days after Easter, is one of the chief feasts of the Christian year. The feast dates back at least to the later 4th century, as is widely attested.
The account of Jesus ascending bodily into the clouds is given fully only in the Acts of the Apostles, but is briefly described also in the Gospel of Luke (often considered to be by the same author) at 24:5053 and in the ending of Mark 16 at 16:19.
