Who only has immortality, dwelling in the light which no man can approach unto; whom no man has seen, nor can see: to whom be honor and power everlasting. Amen.
All Commentaries on 1 Timothy 6:16 Go To 1 Timothy 6
Augustine of Hippo
AD 430
God, Father Son and Holy Spirit, is in his own proper nature invisible. But he has appeared when he wished and to whom he wished; not as he is but in whatever way he wished, being served after all by all creation. If your mind, though it is invisible in your body, can appear by uttering your voice, and the voice in which your mind appears when you speak is not the substance of your mind, it means that mind is one thing and voice another, and yet mind becomes apparent in a thing which in itself is not. So too God, if he appeared in fire, is all the same not fire; if he appeared in smoke, still he isn’t smoke; if he appeared in a sound, he isn’t a sound. These things are not God, but they indicate God. If we bear this in mind, we may safely believe that it could have been the Son who appeared to Moses and was called both Lord and angel of the Lord.
