On the Feast of the Ascension of Our Lord Jesus Christ in the Roman Rite.

“And Jesus coming, spoke to them, saying: ‘All power is given to me in heaven and in earth. Going, therefore, teach ye all nations: baptizing them in the name of the Father, and of the Son, and of the Holy Ghost; Teaching them to observe all things whatsoever I have commanded you: and behold I am with you all days, even to the consummation of the world.'” (St. Matthew xxviii, 18-20)
