“Yes, in the sea of life in-isled,
With echoing straits between us thrown,
Dotting the shoreless watery wild,
We mortal millions live alone.
God bade betwixt ‘our’ shores to be
The unplumb’d, salt, estranging sea.”
And yet, incredible as the paradox would seem, if it were not too common to be strange, the play of muscles and rush of blood, visible through the skin, do reveal the most spiritual and immaterial changes. Even so the heavens declare that very glory of God which baffled the undimmed eyes of Moses. So it was, also, that when rended rocks and burning skies revealed a more immanent action of Him Who moves through all nature always, when convulsions hitherto undreamed of by those dwellers in Egyptian plains overwhelmed them with a new sense of their own smallness and a supreme Presence, God was manifested there.
Not unlike this is the explanation of St. Augustine, “We need not be surprised that God, invisible as He is, appeared visibly to the patriarchs. For, as the sound which communicates the thought conceived in the silence of the mind is not the thought itself, so the form by which God, invisible in His own nature, became visible, was not God Himself. Nevertheless it was He Himself Who was seen under that form, as the thought itself is heard in the sound of the voice; and the patriarchs recognised that, although the bodily form was not God, they saw the invisible God. For, though Moses was conversing with God, yet he said, ‘If I have found grace in Thy sight, show me Thyself’” (De Civ. Dei, x. 13). And again: “He knew that he saw corporeally, but he sought the true vision of God spiritually” (De Trin., ii. 27).
It has still to be added that His manifestation is exactly suited to the stage now reached in the education of Israel. Their fathers had already “seen God” in the likeness of man: Abraham had entertained Him; Jacob had wrestled with Him. And so Joshua before Ai, and Manoah by the rock at Zorah, and Ezekiel by the river Chebar, should see the likeness of a man. We who believe the doctrine of a real Incarnation can well perceive that in these passing and mysterious glimpses God was not only revealing Himself in the way which would best prepare humanity for His future coming in actual manhood, but also in the way by which, meanwhile, the truest and deepest light could be thrown upon His nature, a nature which could hereafter perfectly manifest itself in flesh. Why, then, do not the records of the Exodus hint at a human likeness? Why did they “behold no similitude”? Clearly because the masses of Israel were utterly unprepared to receive rightly such a vision. To them the likeness of man would have meant no more than the likeness of a flying eagle or a calf. Idolatry would have followed, but no sense of sympathy, no consciousness of the grandeur and responsibility of being made in the likeness of God. Anthropomorphism is a heresy, although the Incarnation is the crowning doctrine of the faith.
But it is hard to see why the human likeness of God should exist in Genesis and Joshua, but not in the history of the Exodus, if that story be a post-Exilian forgery.
This is not all. The revelations of God in the desert were connected with threats and prohibitions: the law was given by Moses; grace and truth came by Jesus Christ. And with the different tone of the message a different aspect of the speaker was to be expected. From the blazing crags of Sinai, fenced around, the voice of a trumpet waxing louder and louder, said “Thou shalt not!” On the green hill by the Galilæan lake Jesus sat down, and His disciples came unto Him, and He opened His mouth and said “Blessed.”
Now, the conscience of every sinner knows that the God of the commandments is dreadful. It is of Him, not of hell, that Isaiah said “The sinners in Zion are afraid; trembling hath surprised the godless ones. Who among us shall dwell with the devouring fire? who among us shall dwell with everlasting burnings?” (Isa. xxxiii. 14).
For him who rejects the light yoke of the Lord of Love, the fires of Sinai are still the truest revelation of deity; and we must not deny Sinai because we know Bethlehem. We must choose between the two.
