The Ascension of Our Lord

Forty days after the Resurrection, our Lord Jesus Christ, attended by Angels, ascended into heaven, in the sight of His most holy Mother, His Apostles, and disciples, to the great wonder of them all.

St. Paul declares that God "hath made us sit together in the heavenly places, through Christ Jesus." "There where the Head has gone, the Body is called to follow."
The Roman Missal, 1962

Ye men of Galilee, why wonder you, looking up to heaven? alleluia. He shall so come as you have seen Him going up into heaven, alleluia, alleluia, alleluia.

O clap your hands, all ye nations; shout unto God, with the voice of exultation!

Glory be to the Father, and to the Son and to the Holy Ghost. As it was in the beginning is now and ever shall be world without end.

Ye men of Galilee, why wonder you, looking up to heaven? alleluia. He shall so come as you have seen Him going up into heaven, alleluia, alleluia, alleluia.
Introit (Acts 1.11)
