Apringius of Beja — on Rev 3:12 (TRACTATE ON THE APOCALYPSE 3:12)

“[I will write on him the name of my God] so that he might be signed with the divine name and be adorned with the glory of immortality and might receive the name of the divine city of Jerusalem, which is the vision of peace, and so fully enjoy the society of perpetual quiet and security. This is that city which descends out of heaven from God, so that the saints might dwell and repose within it "And my new name." In God nothing is old, because he does grow old with age. But the name of the Lord is always new, always fresh. And if any is named by this name, having been changed by the eternal power, he will obtain eternal life.”
