Psalms 1:2

4. Now the law has figuratively predicted all these, delineating man by the [various] animals: whatsoever of these, says [the Scripture], have a double hoof and ruminate, it proclaims as clean; but whatsoever of them do not possess one or other of these [properties], it sets aside by themselves as unclean. Who then are the clean? Those who make their way by faith steadily towards the Father and the Son; for this is denoted by the steadiness of those which divide the hoof; and they meditate day and night upon the words of God, that they may be adorned with good works: for this is the meaning of the ruminants. The unclean, however, are those which do neither divide the hoof nor ruminate; that is, those persons who have neither faith in God, nor do meditate on His words: and such is the abomination of the Gentiles. …

For the persuasive style of sentence in one form becomes hortatory, and in another dehortatory. So also the panegyrical in one form becomes inculpatory, and in another laudatory. And in these exercises the Instructor, the Just One, who has proposed our advantage as His aim, is chiefly occupied. But the inculpatory and dehortatory forms of speech have been already shown us; and we must now handle the persuasive and the laudatory, and, as on a beam, balance the equal scales of justice. The exhortation to what is useful, the Instructor employs by Solomon, to the following effect: “I exhort you, O men; and I utter my voice to the sons of men. Hear me; for I will speak of excellent things;” and so on. …

By encouragement He assuages sins, reducing lust, and at the same time inspiring hope for salvation. For He says by Ezekiel, “If ye return with your whole heart, and say, Father, I will hear you, as a holy people.” And again He says, “Come all to Me, who labour, and are heavy laden, and I will give you rest;” and that which is added the Lord speaks in His own person. And very clearly He calls to goodness by Solomon, when He says, “Blessed is the man who hath found wisdom, and the mortal who hath found understanding.” “For the good is found by him who seeks it, and is wont to be seen by him who has found it.” By Jeremiah, too, He sets forth prudence, when he says, “Blessed are we, Israel; for what is pleasing to God is known by us; and it is known by the Word, by whom we are blessed and wise. …

David, too, and Moses before David, show the knowledge of the three precepts in the following words: “Blessed is the man who walks not in the counsel of the ungodly;” as the fishes go down to the depths in darkness; for those which have not scales, which Moses prohibits touching, feed at the bottom of the sea. “Nor standeth in the way of sinners,” as those who, while appearing to fear the Lord, commit sin, like the sow, for when hungry it cries, and when full knows not its owner. “Nor sitteth in the chair of pestilences,” as birds ready for prey. And Moses enjoined not to eat the sow, nor the eagle, nor the hawk, nor the raven, nor any fish without scales. So far Barnabas. And I heard one skilled in such matters say that “the counsel of the ungodly” was the heathen, and “the way of sinners” the Jewish persuasion, and explain “the chair of pestilence” of heresies. …

But “let your works shine,” saith He; but now all our shops and gates shine! You will now-a-days find more doors of heathens without lamps and laurel-wreaths than of Christians. What does the case seem to be with regard to that species (of ceremony) also? If it is an idol’s honour, without doubt an idol’s honour is idolatry. If it is for a man’s sake, let us again consider that all idolatry is for man’s sake; let us again consider that all idolatry is a worship done to men, since it is generally agreed even among their worshippers that aforetime the gods themselves of the nations were men; and so it makes no difference whether that superstitious homage be rendered to men of a former age or of this. Idolatry is condemned, not on account of the persons which are set up for worship, but on account of those its observances, which pertain to demons. …

But even in the common transactions of life, and of human intercourse at home and in public, even to the care of the smallest vessels, He in every possible manner made distinct arrangement; in order that, when they everywhere encountered these legal instructions, they might not be at any moment out of the sight of God. For what could better tend to make a man happy, than having “his delight in the law of the Lord?” “In that law would he meditate day and night.” It was not in severity that its Author promulgated this law, but in the interest of the highest benevolence, which rather aimed at subduing the nation’s hardness of heart, and by laborious services hewing out a fealty which was (as yet) untried in obedience: for I purposely abstain from touching on the mysterious senses of the law, considered in its spiritual and prophetic relation, and as abounding in types of almost every variet …

LXI . But if any one allege the pretence of his own work, and so is a despiser, “offering pretences for his sins,” let such a one know that the trades of the faithful are works by the by, but the worship of God is their great work. Follow therefore your trades as by the by, for your maintenance, but make the worship of God your main business; as also our Lord said: “Labour not for the meat which perishes, but for that which endureth unto everlasting life.” And again: “This is the work of God, that ye believe on Him whom He hath sent.” Endeavour therefore never to leave the Church of God; but if any one overlooks it, and goes either into a polluted temple of the heathens, or into a synagogue of the Jews or heretics, what apology will such a one make to God in the day of judgment, who has forsaken the oracles of the living God, and the living and quickening oracles, such as are able to del …

XXIII . For He did not take away the law of nature, but confirmed it. For He that said in the law, “The Lord thy God is one Lord;” the same says in the Gospel, “That they might know Thee, the only true God.” And He that said, “Thou shalt love thy neighbour as thyself,” says in the Gospel, renewing the same precept, “A new commandment I give unto you, that ye love one another.” He who then forbade murder, does now forbid causeless anger. He that forbade adultery, does now forbid all unlawful lust. He that forbade stealing, now pronounces him most happy who supplies those that are in want out of his own labours. He that forbade hatred, now pronounces him blessed that loves his enemies. He that forbade revenge, now commands long-suffering; not as if just revenge were an unrighteous thing, but because long-suffering is more excellent. …

Now since “every scribe who has been made a disciple to the kingdom of heaven is like unto a man that is a householder who bringeth forth out of his treasury things new and old,” it clearly follows, by “conversion of the proposition,” as it is called, that every one who does not bring forth out of his treasury things new and old, is not a scribe who has been made a disciple unto the kingdom of heaven. We must endeavour, therefore, in every way to gather in our heart, “by giving heed to reading, to exhortation, to teaching,” and by “meditating in the law of the Lord day and night,” not only the new oracles of the Gospels and of the Apostles and their Revelation, but also the old things in the law “which has the shadow of the good things to come,” and in the prophets who prophesied in accordance with them. …

1. Hear, O Donatists, what the Catholic Church says to you: “O ye sons of men, how long will ye be slow of heart? why will ye love vanity, and follow after lies?” Why have you severed yourselves, by the heinous impiety of schism, from the unity of the whole world? You give heed to the falsehoods concerning the surrendering of the divine books to persecutors, which men who are either deceiving you, or are themselves deceived, utter in order that you may die in a state of heretical separation: and you do not give heed to what these divine books themselves proclaim, in order that you may live in the peace of the Catholic Church. Wherefore do you lend an open ear to the words of men who tell you things which they have never been able to prove, and are deaf to the voice of God speaking thus: “The Lord hath said unto me, Thou art My Son; this day have I begotten Thee. …

5. Further let me ask of my reader, wherever, alike with myself, he is certain, there to go on with me; wherever, alike with myself, he hesitates, there to join with me in inquiring; wherever he recognizes himself to be in error, there to return to me; wherever he recognizes me to be so, there to call me back: so that we may enter together upon the path of charity, and advance towards Him of whom it is said, “Seek His face evermore.” And I would make this pious and safe agreement, in the presence of our Lord God, with all who read my writings, as well in all other cases as, above all, in the case of those which inquire into the unity of the Trinity, of the Father and the Son and the Holy Spirit; because in no other subject is error more dangerous, or inquiry more laborious, or the discovery of truth more profitable. …

“See,” he says, “how this epistle will clear me before your Blessedness; for in it we clearly and simply declare, that we possess a free will which is unimpaired for sinning and for not sinning; and this free will is in all good works always assisted by divine help.” Now you perceive, by the understanding which the Lord has given you, that these words of his are inadequate to solve the question. For it is still open to us to inquire what the help is by which he would say that the free will is assisted; lest perchance he should, as is usual with him, maintain that law and teaching are meant. …
