Theophylact of Ohrid
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.
The Spirit had not yet come, and yet their conversation is spiritual. Before they were shut up; now they stand in the midst of the chief priests; distracted by no worldly object, but despising all things, they praise God continually; as it follows, Praising and blessing God.
