When the Church gathers, it regularly remembers Christ’s ascension. The words “He ascended into heaven” are found in the three ecumenical creeds Christians use to confess their faith. In addition, the Church sets aside a day each year to focus on Christ’s ascension. This is for good reason. Jesus’ ascension marked the fact that his work was complete, in one sense. Never again will a sacrifice for sins need to be made. However, Jesus’ ascension also marks that, in another sense, his work is just beginning. Through the Church, Jesus now proclaims forgiveness of sins throughout the world.
The Church consists of people like us who are often weak and timid witnesses for Christ. So, Jesus promised to send us his Spirit to give us power from heaven, that we might take the gospel to the ends of the earth. More, he ascended into heaven and sat down on the throne of God. He lives and reigns over everything for the benefit of his Church.
