When the Church gathers, it regularly remembers Christ's ascension. The  words "He ascended into heaven" are found in all three ecumenical creeds  which we use to confess our faith. In addition, the Church sets aside a  day each year on which this event takes center stage. This is for good  reason. Jesus' ascension marked the fact that his work was complete.  Never again will a sacrifice for sin need to be made. However, Jesus'  ascension also marks that his work is just beginning. Through the Church  Jesus now proclaims forgiveness 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.
