Bede the Venerable
Catena Aurea · Lukasevangelium 24
And he led them out as far as to Bethany, and he lifted up his hands, and blessed them. And it came to pass, while he blessed them, he was parted from them, and carried up into heaven. And they worshipped him, and returned to Jerusalem with great joy: And were continually in the temple, praising and blessing God. Amen.
And observe that among the four beasts in heaven, (Ezek. 1:10. Rev. 4:7) Luke is said to be represented by the calf, for by the sacrifice of a calf, they were ordered to be initiated who were chosen to the priesthood; (Exod. 29:1.) and Luke has undertaken to explain more fully than the rest the priesthood of Christ; and his Gospel, which he commenced with the ministry of the temple in the priesthood of Zacharias, he has finished with the devotion in the temple. And he has placed the Apostles there, about to be the ministers of a new priesthood, not in the blood of sacrifices, but in the praises of God and inblessing, that in the place of prayer and amidst the praises of their devotion, they might wait with prepared hearts for the promise of the Spirit.
