On the World and the Movements of Rational Creatures, Whether Good or Bad; And on the Causes of Them
7 But even holy Scripture does not appear to me to be altogether silent on the nature of this secret, as when the Apostle Paul, in discussing the case of Jacob and Esau, says: “For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of Him who calls, it was said, The elder shall serve the younger, as it is written, Jacob have I loved, but Esau have I hated.” And after that, he answers himself, and says, “What shall we say then? Is there unrighteousness with God?” And that he might furnish us with an opportunity of inquiring into these matters, and of ascertaining how these things do not happen without a reason, he answers himself, and says, “God forbid.” For the same question, as it seems to me, which is raised concerning Jacob and Esau, may be raised regarding all celestial and terrestrial creatures, and even those of the lower world as well. And in like manner it seems to me, that as he there says, “The children being not yet born, neither having done any good or evil,” so it might also be said of all other things, “When they were not yet” created, “neither had yet done any good or evil, that the decree of God according to election may stand,” that (as certain think) some things on the one hand were created heavenly, some on the other earthly, and others, again, beneath the earth, “not of works” (as they think), “but of Him who calls,” what shall we say then, if these things are so? “Is there unrighteousness with God? God forbid.” As, therefore, when the Scriptures are carefully examined regarding Jacob and Esau, it is not found to be unrighteousness with God that it should be said, before they were born, or had done anything in this life, “the elder shall serve the younger;” and as it is found not to be unrighteousness that even in the womb Jacob supplanted his brother, if we feel that he was worthily beloved by God, according to the deserts of his previous life, so as to deserve to be preferred before his brother; so also is it with regard to heavenly creatures, if we notice that diversity was not the original condition of the creature, but that, owing to causes that have previously existed, a different office is prepared by the Creator for each one in proportion to the degree of his merit, on this ground, indeed, that each one, in respect of having been created by God an understanding, or a rational spirit, has, according to the movements of his mind and the feelings of his soul, gained for himself a greater or less amount of merit, and has become either an object of love to God, or else one of dislike to Him; while, nevertheless, some of those who are possessed of greater merit are ordained to suffer with others for the adorning of the state of the world, and for the discharge of duty to creatures of a lower grade, in order that by this means they themselves may be participators in the endurance of the Creator, according to the words of the apostle: “For the creature was made subject to vanity, not willingly, but by reason of him who has subjected the same in hope.” Keeping in view, then, the sentiment expressed by the apostle, when, speaking of the birth of Esau and Jacob, he says, “Is there unrighteousness with God? God forbid,” I think it right that this same sentiment should be carefully applied to the case of all other creatures, because, as we formerly remarked, the righteousness of the Creator ought to appear in everything. And this, it appears to me, will be seen more clearly at last, if each one, whether of celestial or terrestrial or infernal beings, be said to have the causes of his diversity in himself, and antecedent to his bodily birth. For all things were created by the Word of God, and by His Wisdom, and were set in order by His Justice. And by the grace of His compassion He provides for all men, and encourages all to the use of whatever remedies may lead to their cure, and incites them to salvation.
8. As, then, there is no doubt that at the day of judgment the good will be separated from the bad, and the just from the unjust, and all by the sentence of God will be distributed according to their deserts throughout those places of which they are worthy, so I am of opinion some such state of things was formerly the case, as, God willing, we shall show in what follows. For God must be believed to do and order all things and at all times according to His judgment. For the words which the apostle uses when he says, “In a great house there are not only vessels of gold and silver, but also of wood and of earth, and some to honour and some to dishonour;” and those which he adds, saying, “If a man purge himself, he will be a vessel unto honour, sanctified and meet for the Master's use, unto every good work,” undoubtedly point out this, that he who shall purge himself when he is in this life, will be prepared for every good work in that which is to come; while he who does not purge himself will be, according to the amount of his impurity, a vessel unto dishonour, i.e., unworthy. It is therefore possible to understand that there have been also formerly rational vessels, whether purged or not, i.e., which either purged themselves or did not do so, and that consequently every vessel, according to the measure of its purity or impurity, received a place, or region, or condition by birth, or an office to discharge, in this world. All of which, down to the humblest, God providing for and distinguishing by the power of His wisdom, arranges all things by His controlling judgment, according to a most impartial retribution, so far as each one ought to be assisted or cared for in conformity with his deserts. In which certainly every principle of equity is shown, while the inequality of circumstances preserves the justice of a retribution according to merit. But the grounds of the merits in each individual case are only recognised truly and clearly by God Himself, along with His only-begotten Word, and His Wisdom, and the Holy Spirit.
