Tertullian
Patristic
c. A.D. 150–220
“Now who was it that said; "Let there be light? " And who was it that said to Christ concerning giving light to the world: "I have set Thee as a light to the Gentiles" -to them, that is, "who sit in darkness and in the shadow of death? " (None else, surely, than He), to whom the Spirit in the Psalm answers, in His foresight of the future, saying, "The light of Thy countenance, O Lord, hath been displayed upon us.”
