Primasius of Hadrumetum — on Rev 10:2 (COMMENTARY ON THE APOCALYPSE 10:2)

“If earlier the deep secrets of the Old Testament were recognized to have been hidden in the sealed book, it is appropriate that the revealed grace of the New Testament is believed to be disclosed here in the opened book. Therefore, the apostle confidently says, "And we, with unveiled face, beholding the glory of the Lord, are being changed into his likeness from glory to glory, as though by the Spirit of the Lord." Indeed, this is why his face is said to shine like the sun. Moreover, the right foot upon the sea represents those members who are strong so that they might suffer the attacks of persecution.… The left foot upon the land represents those who are not exposed to the greater dangers. For God does not allow us to be tempted beyond what we are able, but with temptation [he] provides also a way, so that we might endure. It is certain, nonetheless, that the proclamation is extended by way of land and sea.”
