John Chrysostom — on 1Tim 6:15 (Homily on 1 Timothy 18)

“"Which in His times He shall show, Who is the blessed and only Potentate, King of kings, and Lord of lords, Who only hath immortality, dwelling in the light which no man can approach unto." Of whom are these things said? Of the Father, or of the Son? Of the Son, undoubtedly: and it is said for the consolation of Timothy, that he may not fear nor stand in awe of the kings of the earth. "In His times," that is, the due and fitting times, that he may not be impatient, because it has not yet come. And whence is it manifest, that He will show it? Because He is the Potentate, the "only Potentate." He then will show it, Who is "blessed," nay blessedness itself; and this is said, to show that in that appearing there is nothing painful or uneasy. But he says, "only," either in contradistinction to men, or because He was unoriginated, or as we sometimes speak of a man whom we wish to extol. "Who only hath immortality." What then? hath not the Son immortality? Is He not immortality itself? How should not He, who is of the same substance with the Father, have immortality?”
