Go you therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
An ancient writer informs us that when the Egyptians named their greatest God who was over all, they cried thrice, "Darkness! Darkness! Darkness!" In the name of the Father — Darkness; and of the Son — Darkness; and of the Holy Ghost — Darkness! for, however much the mind may strive to penetrate this mystery, it can never attain to its solution. Just as the eye, looking at the sun, sees the overpowering light as a dark ball, being dazzled by its excessive glory, so the eye of the mind perceives only darkness when looking into the infinite splendour of God in Three Persons. We may, indeed, see sundry likenesses here on earth which assist us in believing the doctrine of the Holy Trinity; but they are helps, and helps only, not explanations. Thus, the sun may shine into a glass, and the glass reflect in clear water, and we see three suns — a sun in the heavens, a sun in the glass, and a sun in the water; and this assists us to understand how the Son of God is of the Father, and the Holy Ghost is of the Father and of the Son, and how that each is God, and yet that there are not Three Gods but One God. But, after all, the doctrine of the Holy Trinity is a matter of faith, and not of reason. We must believe, though we cannot understand.
(S. Baring Gould.)
