Ascension Day - forty days after Christ arose from the dead, the final act of our redemption. (Luke 24:51; Mark 16:19; Acts 1:9-11). Professed in the earliest creeds - Apostles Creed. and the Nicene Creed.
Collect for the Feast of the Ascension (from the Mass of St. Pius V) :
Grant, we beseech Thee, almighty God, that we who believe Thine only-begotten Son, our Redeemer, to have this day ascended into heaven, may dwell in spirit amid heavenly things. Through the same Lord Jesus Christ, Thy Son, Who liveth and reigneth with Thee in the unity of the Holy Ghost, God, world without end. Amen.
