13. And every oblation of thy meat-offering. The reason for salting the victims was very similar, viz., that God’s service might not be without savor; but the true seasoning which gives grace to sacrifices is found nowhere except in God’s word. Hence it follows that all modes of worship fabricated by men are rejected as unsavory. For although they who profane God’s worship by superstitions think themselves very acute, yet all that most approves itself to them under the cloak of wisdom is mere fatuity. Nevertheless, Christ deduces an exhortation from this ceremony, viz., that believers, if they desire to please God, should patiently endure to be refined and purified. “Every one,” He says,
"shall be salted with fire, and every sacrifice shall be salted with salt.” (Mark 9:49.)
In which words He signifies that, when we are searched and tried by fire, we shall be acceptable sacrifices to God, and that this is the seasoning of salt when our flesh with its affections shall have been well macerated. Meanwhile, let us firmly hold to this, that our service of God is not what it should be without, the savor which is to be sought in the word; since in all the brains of men not one particle of salt is to be found. I pass by other more subtle allegories, in which I see no other use than to gratify curious ears. “The salt of the covenant” is used in a different sense from “the covenant of salt,” viz., as the salt which is employed in the sacrifice according to the inviolable compact of God. Hence, too, is confirmed what I have said before, that the keeping of God’s covenant always occupies the first place in this service.
