Cyril of Alexandria — as excerpted in the Catena Aurea on Luke 4:1-4

“God said in times past, My Spirit shall not always abide in men, for that they are flesh. (Gen. 6:3. Vulg.) But now that we have been enriched with the gift of regeneration by water and the Spirit, we are become partakers of the Divine nature by participation of the Holy Spirit. But the first-born among many brethren first received the Spirit, who Himself also is the giver of the Spirit, that we through Him might also receive the grace of the Holy Spirit.”
