Commentary on Isaiah Volume 1 John Calvin (continued)
JOHN CALVIN
We must not conclude, therefore, that Isaiah's lips were impure, because they are now cleansed; but we ought to inquire why it is done. It was because the Lord intended to enlarge and extend his favor towards him, and to raise him to higher dignity, that he might have greater influence over the people; and this was rendered necessary by the character of the times, and the change which had taken place in the state.
The fire was taken from the altar, to intimate that it was divine or heavenly; for the law forbade any strange fire to be brought to it, (Leviticus 10:1,) because in sacred things every human mixture is absolute profanation. By this figure, therefore, Isaiah was taught that all purity flows from God alone.
7. And applying it to my mouth. 97 We see how God condescends to meet the weakness of human sense. He puts the tongs into the hand of a seraph, that by means of it he may take a coal from the altar and apply it to the Prophet's mouth. This was, no doubt, done in vision; but by the aid of the outward sign God assisted the Prophet's understanding. There is no reason to believe that the coal possessed any virtue, as superstitious persons imagine that in the magical arts there is some hidden power. Nothing of this sort is to be found here; for it is God alone who can cleanse our pollution, in whatever part it exists.
Here the angel administered the cleansing, but was not the author of it; so that we must not ascribe to another what belongs to God alone. This is expressly stated by the angel himself, who claims nothing as his own, but bringing forward the sacred pledge which he had received from God, laid it as a sacrament on the lips of the Prophet; not that he could not be cleansed without the coal, but because the visible sign was useful for the confirmation and proof of the fact. And such is the use of sacraments, to strengthen us in proportion to our ignorance; for we are not angels, that can behold the mysteries of God without any assistance, and therefore he raises us to himself by gradual advances.
Lo, this hath touched thy lips. He shows that the confirmation which was obtained by the sign was not without effect, but that the blessing signified by it was at the same time bestowed, so that Isaiah knew that he had not been deceived. Hence we may infer, that in the sacraments the reality is given to us along with the sign; for when the Lord holds out a sacrament, he does not feed our eyes with an empty and unmeaning figure, but joins the truth with it, so as to testify that by means of them he acts upon us efficaciously. And this ought to be the more carefully observed, because there are few persons in the present day who understand the true use of sacraments, and because many godly and learned men are engaged in frequent disputes respecting them.
First of all, we ought to believe that the truth must never be separated from the signs, though it ought to be distinguished from them. We perceive and feel a sign, such as the bread which is put into our hands by the minister
97And he said, Go, and tell this people. — Eng. Ver.
