But we all, with unveiled face beholding as in a mirror the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.
All Commentaries on 2 Corinthians 3:18 Go To 2 Corinthians 3
Gregory the Theologian
AD 390
For the matter stands thus: The Old Testament proclaimed the Father openly and the Son more obscurely. The New manifested the Son and suggested the deity of the Spirit. Now the Spirit himself dwells among us and supplies us with a clearer demonstration of himself. For it was not safe, when the Godhead of the Father was not yet acknowledged, plainly to proclaim the Son; nor when that of the Son was not yet received, to burden us further (if I may use so bold an expression) with the Holy Ghost… . For this reason it was, I think, that he gradually came to dwell in the disciples, measuring himself out to them according to their capacity to receive him, at the beginning of the gospel, after the passion, after the ascension, making perfect their powers, being breathed upon them and appearing in fiery tongues. And indeed it is by little and little that he is declared by Jesus, as you will learn for yourself if you will read more carefully.
