Endnote 17 – Witnessing the Divine
Irenaeus, Adversus omnes Haerses 3.9. In the fifth century, Leo the Great repeats this interpretation in Sermon 33, 34, 36 where he speaks of the One Person with a “three-fold function”: God, mortal human, and king. Compare Fulgentius of Ruspe (a North African writer, c. 467–533), Letter to Ferrandus 20.
