Introit for the Ascension Viri Galilaei, quid admiramini aspicientes in caelum?
alleluia: quemadmodum vidistis eum ascendentem in caelum, ita veniet,
alleluia, alleluia, alleluia.
Omnes gentes plaudite manibus: iubilate Deo in voce exsultationus.
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.
The Venerable Bede had a special devotion to the Antiphon of the Magnificat for the Ascension, as he himself was an orphan. St Cuthbert narrates the death of Bede on the Vigil of the Ascension.
qui triumphator hodie super omnes caelos ascendisti:
ne derelinquas nos orphanos, sed mitte promissum Patris in nos,
Spiritum veritatis. Alleluia.
