The Account in Luke and Acts

Among the four Gospels, only Luke narrates the ascension as a distinct scene, briefly at the close of his Gospel and at greater length in the opening chapter of Acts, a second volume by the same author addressed to the same recipient. Acts places the event forty days after the resurrection, on the Mount of Olives outside Jerusalem, with Jesus lifted up and a cloud taking him from the apostles' sight.

Matthew and John contain no explicit ascension scene at all, ending their resurrection narratives without describing a final departure, and the longer ending of Mark, which does mention an ascension, is judged by most textual critics, following the manuscript evidence assembled in works such as Bruce Metzger's standard commentary on the Greek New Testament, to be a later addition not present in that gospel's earliest surviving copies. Commentators generally read the forty day figure itself as following a recurring biblical pattern rather than a claim of precise reckoning, since forty days or forty years mark several other pivotal periods across the Hebrew Bible and the Gospels, including Moses's time on Sinai and Jesus's own temptation in the wilderness. Acts describes the interval as filled with continued teaching and appearances rather than as a period the apostles simply waited out, and it is this same forty day window that later Christian calendars use to fix Ascension Day as a moveable feast tied to Easter's own date.
