Cyril of Alexandria
Catena Aurea · Lukasevangelium 10
In that hour Jesus rejoiced in spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou hast hid these things from the wise and prudent, and hast revealed them unto babes: even so, Father; for so it seemed good in thy sight. All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and he to whom the Son will reveal him.
He saw in truth that through the operation of the Holy Spirit, which He gave to the holy Apostles, the acquisition of many would be made, (or that many would be brought to the faith.) He is said therefore to have rejoiced in the Holy Spirit, that is, in the results which came forth through the Holy Spirit. For as one who loved mankind He considered the conversion of sinners to be a subject for rejoicing, for which He gives thanks. As it follows, I give thanks unto thee, O Father.
