Psalms 79:6

6.Pour out thy fury upon the heathen, who have not known thee. This prayer is apparently inconsistent with the rule of charity; for, while we feel anxious about our own calamities, and desire to be delivered from them, we ought to desire that others may be relieved as well as ourselves. It would seem, therefore, that the faithful are to be blamed in here wishing the destruction of unbelievers, for whose salvation they ought rather to have been solicitous. But it becomes us to bear in mind what I have previously stated, that the man who would offer up such a prayer as this in a right manner, must be under the influence of zeal for the public welfare; so that, by the wrongs done to himself personally, he may not suffer his carnal affections to be excited, nor allow himself to be carried away with rage against his enemies; but, forgetting his individual interests, he must have a sole regard to the common salvation of the Church, and to what conduces thereto. Secondly, he must implore God to grant him the spirit of discretion and judgment, that in prayer he may not be impelled by an inconsiderate zeal: a subject which we have treated more at large in another place. Besides, it is to be observed, that the pious Jews here not only lay out of consideration their own particular advantage in order to consult the good of the whole Church, but also chiefly direct their eyes to Christ, beseeching him to devote to destruction his enemies whose repentance is hopeless. They, therefore, do not rashly break forth into this prayer, that God would destroy these or other enemies, nor do they anticipate the judgment of God; but desiring that the reprobate may be involved in the condemnation which they deserve, they, at the same time, patiently wait until the heavenly judge separate the reprobate from the elect. In doing this, they do not cast aside the affection which charity requires; for, although they would desire all to be saved, they yet know that the reformation of some of the enemies of Christ is hopeless, and their perdition absolutely certain.

The question, however, is not yet fully answered; for, when in the seventh verse they arraign the cruelty of their enemies, they seem to desire vengeance. But what I have just now observed must be remembered, that none can pray in this manner but those who have clothed themselves with a public character, and who, laying aside all personal considerations, have espoused, and are deeply interested in, the welfare of the whole Church; or, rather, who have set before their eyes Christ, the Head of the Church; and, lastly, none but those who, under the guidance of the Holy Spirit, have elevated their minds to the judgment of God; so that, being ready to forgive, they do not indiscriminately adjudge to death every enemy by whom they are injured, but only the reprobate. With regard to those who make haste in demanding the execution of the Divine vengeance before all hope of repentance is lost, Christ has condemned them as chargeable with inconsiderate and ill-regulated zeal, when he says,

“Ye know not what manner of spirit ye are of,”
(Luke 9:55.)

Moreover, the faithful do not here simply wish the destruction of those who so wickedly persecuted the Church, but, using that familiarity which God allows them in their dealings with him, they set forth how inconsistent it would be did he not punish their persecutors, (375) and reason thus: Lord, how is it that thou afflictest us so severely, upon whom thy name is invoked, and sparest the heathen nations who despise thee? In short, they mean to say, that God has sufficient ground for executing his wrath elsewhere, since they were not the only people in the world who had sinned. Although it does not become us to prescribe to God the rule of his conduct, but rather patiently to submit to this ordination,

“That judgment must begin at the house of God”
(1 Peter 4:17;)

yet he permits his saints to take the liberty of pleading, that at least they may not be worse dealt with than unbelievers, and those who despise him.

These two sentences, who have not known thee, and which call not upon thy name, it is to be observed, are to be taken in the same sense. By these different forms of expression, it is intimated that it is impossible for any to call upon God without a previous knowledge of him, as the Apostle Paul teaches, in Romans 10:14,

“How, then, shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard?” (Romans 10:14)

It belongs not to us to answer, “Thou art our God,” till He has anticipated us by saying, “Thou art my people,” (Hosea 2:23;) but he opens our mouths to speak to him in this manner, when he invites us to himself. Calling on the name of God is often synonymous with prayer; but it is not here to be exclusively limited to that exercise. The amount is, that unless we are directed by the knowledge of God, it is impossible for us sincerely to profess the true religion. At that time the Gentiles everywhere boasted that they served God; but, being destitute of his word, and as they fabricated to themselves gods of their own corrupt imaginations, all their religious services were detestable; even as in our own day, the human invented religious observances of the blind and deluded votaries of the Man of Sin, who have no right knowledge of the God whom they profess to worship, and who inquire not at his mouth what he approves, are certainly rejected by Him, because they set up idols in his place.
