711. What is the significance of Ascension Day?

On Ascension Day we are reminded that Jesus Christ ascended into heaven out of the circle of the Apostles on the fortieth day after Easter. “He was taken up, and a cloud received Him out of their sight.” Through two angels the Apostles received the promise: “This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven” (Acts 1: 3-11).
