I am in no position to teach the Bishop of Salisbury about patristics, but what dear old Irenaeus wrote was “For the glory of God is a living man” (Gloria enim Dei vivens homo). He wrote in Greek, but that bit only survives in Latin. It comes in his masterpiece Adversus Haereses, the point of which is the central belief of Christianity: that God became a man; the Word was made flesh.
The Word of God, Irenaeus says in this paragraph (Book IV; 20:7), dispensed the fatherly grace of God, revealing God to man. (By “man”, homo, he means the kind of creature we humans are. We are also persons, but so are the persons of the Holy Trinity, so that word is better avoided here.)
The Word, Irenaeus wrote, “also protected the invisibility of the Father lest man should ever come to despise God”. However, “He made God visible to man by many methods lest man, entirely falling away from God, should cease to exist”.
Then comes the famous quotation: “For a living man is the glory of God; but the vision of God is the life of man.”
A wonderful reflection on the eve of Holy Cross day, 14th September. Thank you to both Kendall and Christopher
