Were there, speaking generally, such sacrifices in the wilderness when the Hebrews wandered through it? No, we shall say, there were not. For the inclination toward idol-worship brought out of Egypt was alive in the hearts of the Hebrew people throughout the whole period of wandering.
God Himself assures us of this through the holy prophet Ezekiel. The Lord says that despite His exhortations, while living in Egypt the Hebrews "did not forsake the idols of Egypt."
Even after leaving Egypt, "their hearts were attached to their idols." For this they were condemned to die without seeing the promised land.
The Lord addressed the children of these who perished with the same exhortation. But the children, says the Lord, "turned their eyes to the idols of their fathers." Thus, after all His exhortations, He "permitted them to be defiled by offerings to idols."
This continued until the very occupation of the land of Palestine, and afterward as well (Ezek 20:8, 16, 24, 26, 28).
It is also known that in the wilderness the Hebrews worshiped the golden calf and served the abominable Baal of Peor (Num 23:28; Num 25:1ff.).
Saint Stephen says that after the casting of the golden calf, God turned away from the Hebrews and left them to serve the host of heaven, that is, the heavenly luminaries.
In the next verse of the chapter under consideration, Saint Amos says that at that same time the Hebrews served Moloch, honored Remphan, and carried idols.
If one adds to this the constant rebellions and murmuring of the stiff-necked people in the wilderness, together with their open regrets over having left Egypt (Num 14:3ff.), their various vices, superstitions, ignorance. Failure to understand the spirit of true service, and ingratitude before God, then one may confidently say that, speaking generally, the Hebrews did not offer true sacrifices to God as they passed through the wilderness. Their sacrifices were defiled by a pagan spirit and by vices.
Strictly speaking, even the lawful Old Testament sacrifices cannot be called true sacrifices to God, satisfying Him and pleasing to Him (Heb 10:1-18). There is only one such sacrifice in the whole world and for all ages: the sacrifice offered by the Savior of the world on the Cross.
Whatever is not in it, according to it, and in its meaning, power, and spirit, in short, whatever is outside it, cannot be a sacrifice to God. But how far the Hebrews in the wilderness were from understanding such a sacrifice.
"Slaughters," σφαγια, means an animal appointed to be slain in sacrifice, from σφαγιαζω, "I slaughter." "Offerings," θυσιας, means sacrifice.
