A comparison is instituted between the disobedient and sinning Eve and the Virgin Mary, her patroness. Various and discordant heresies are mentioned

1. That the Lord then was manifestly coming to His own things, and was sustaining them by means of that creation which is supported by Himself, and was making a recapitulation of that disobedience which had occurred in connection with a tree, through the obedience which was [exhibited by Himself when He hung] upon a tree, [the effects] also of that deception being done away with, by which that virgin Eve, who was already espoused to a man, was unhappily misled,—was happily announced, through means of the truth [spoken] by the angel to the Virgin Mary, who was [also espoused] to a man.⁴⁶¹⁶ For just as the former was led astray by the word of an angel, so that she fled from God when she had transgressed His word; so did the latter, by an angelic communication, receive the glad tidings that she should sustain (portaret) God, being obedient to His word. And if the former did disobey God, yet the latter was persuaded to be obedient to God, in order that the Virgin Mary might become the patroness⁴⁶¹⁷ (advocata) of the virgin Eve. And thus, as the human race fell into bondage to death by means of a virgin, so is it rescued by a virgin; virginal disobedience having been balanced in the opposite scale by virginal obedience. For in the same way the sin of the first created man (protoplasti) receives amendment by the correction of the First-begotten, and the coming of the serpent is conquered by the harmlessness of the dove, those bonds being unloosed by which we had been fast bound to death.

2. The heretics being all unlearned and ignorant of God's arrangements, and not acquainted with that dispensation by which He took upon Him human nature (inscii ejus quæ est secundum hominem dispensationis), inasmuch as they blind themselves with regard to the truth, do in fact speak against their own salvation. Some of them introduce another Father besides the Creator; some, again, say that the world and its substance was made by certain angels; certain others [maintain] that it was widely separated by Horos⁴⁶¹⁸ from him whom they represent as being the Father—that it sprang forth (floruisse) of itself, and from itself was born. Then, again, others [of them assert] that it obtained substance in those things which are contained by the Father, from defect and ignorance; others still, despise the advent of the Lord manifest [to the senses], for they do not admit His incarnation; while others, ignoring the arrangement [that He should be born] of a virgin, maintain that He was begotten by Joseph. And still further, some affirm that neither their soul nor their body can receive eternal life, but merely the inner man. Moreover, they will have it that this [inner man] is that which is the understanding (sensum) in them, and which they decree as being the only thing to ascend to "the perfect." Others [maintain], as I have said in the first book, that while the soul is saved, their body does not participate in the salvation which comes from God; in which [book] I have also set forward the hypotheses of all these men, and in the second have pointed out their weakness and inconsistency.

Chapter XX.—Those pastors are to be heard to whom the apostles committed the Churches, possessing one and the same doctrine of salvation; the heretics, on the other hand, are to be avoided. We must think soberly with regard to the mysteries of the faith.

1. Now all these [heretics] are of much later date than the bishops to whom the apostles committed the Churches; which fact I have in the third book taken all pains to demonstrate. It follows, then, as a matter of course, that these heretics aforementioned, since they are blind to the truth, and deviate from the [right] way, will walk in various roads; and therefore the footsteps of their doctrine are scattered here and there without agreement or connection. But the path of those belonging to the Church circumscribes the whole world, as possessing the sure tradition from the apostles, and gives unto us to see that the faith of all is one and the same, since all receive one and the same God the Father, and believe in the same dispensation regarding the incarnation of the Son of God, and are cognizant of the same gift of the Spirit, and are conversant with the same commandments, and preserve the same form of ecclesiastical constitution,⁴⁶¹⁹ and expect the same advent of the Lord, and await the same salvation of the complete man, that is, of the soul and body. And undoubtedly the preaching of the Church is true and stedfast,⁴⁶²⁰ in which one and the same way of salvation is shown throughout the whole world. For to her is entrusted the light of God; and therefore the "wisdom" of God, by means of which she saves all men, "is declared in [its] going forth; it uttereth [its voice] faithfully in the streets, is preached on the tops of the walls, and speaks continually in the gates of the city."⁴⁶²¹ For the Church preaches the truth everywhere, and she is the seven-branched candlestick which bears the light of Christ.

2. Those, therefore, who desert the preaching of the Church, call in question the knowledge of the holy presbyters, not taking into consideration of how much greater consequence is a religious man, even in a private station, than a blasphemous and impudent sophist.⁴⁶²² Now, such are all the heretics, and those who imagine that they have hit upon something more beyond the truth, so that by following those things already mentioned, proceeding on their way variously, inharmoniously, and foolishly, not keeping always to the same opinions with regard to the same things, as blind men are led by the blind, they shall deservedly fall into the ditch of ignorance lying in their path, ever seeking and never finding out the truth.⁴⁶²³ It behoves us, therefore, to avoid their doctrines, and to take careful heed lest we suffer any injury from them; but to flee to the Church, and be brought up in her bosom, and be nourished with the Lord's Scriptures. For the Church has been planted as a garden (paradisus) in this world; therefore says the Spirit of God, "Thou mayest freely eat from every tree of the garden,"⁴⁶²⁴ that is, Eat ye from every Scripture of the Lord; but ye shall not eat with an uplifted mind, nor touch any heretical discord. For these men do profess that they have themselves the knowledge of good and evil; and they set their own impious minds above the God who made them. They therefore form opinions on what is beyond the limits of the understanding. For this cause also the apostle says, "Be not wise beyond what it is fitting to be wise, but be wise prudently,"⁴⁶²⁵ that we be not cast forth by eating of the "knowledge" of these men (that knowledge which knows more than it should do) from the paradise of life. Into this paradise the Lord has introduced those who obey His call, "summing up in Himself all things which are in heaven, and which are on earth;"⁴⁶²⁶ but the things in heaven are spiritual, while those on earth constitute the dispensation in human nature (secundum hominem est dispositio). These things, therefore, He recapitulated in Himself: by uniting man to the Spirit, and causing the Spirit to dwell in man, He is Himself made the head of the Spirit, and gives the Spirit to be the head of man: for through Him (the Spirit) we see, and hear, and speak.

Chapter XXI.—Christ is the head of all things already mentioned. It was fitting that He should be sent by the Father, the Creator of all things, to assume human nature, and should be tempted by Satan, that He might fulfil the promises, and carry off a glorious and perfect victory.

1. He has therefore, in His work of recapitulation, summed up all things, both waging war against our enemy, and crushing him who had at the beginning led us away captives in Adam, and trampled upon his head, as thou canst perceive in Genesis that God said to the serpent, "And I will put enmity between thee and the woman, and between thy seed and her seed; He shall be on the watch for (observabit⁴⁶²⁷ ) thy head, and thou on the watch for His heel."⁴⁶²⁸ For from that time, He who should be born of a woman, [namely] from the Virgin, after the likeness of Adam, was preached as keeping watch for the head of the serpent. This is the seed of which the apostle says in the Epistle to the Galatians, "that the law of works was established until the seed should come to whom the promise was made."⁴⁶²⁹ This fact is exhibited in a still clearer light in the same Epistle, where he thus speaks: "But when the fulness of time was come, God sent forth His Son, made of a woman."⁴⁶³⁰ For indeed the enemy would not have been fairly vanquished, unless it had been a man [born] of a woman who conquered him. For it was by means of a woman that he got the advantage over man at first, setting himself up as man's opponent. And therefore does the Lord profess Himself to be the Son of man, comprising in Himself that original man out of whom the woman was fashioned (ex quo ea quæ secundum mulierem est plasmatio facta est), in order that, as our species went down to death through a vanquished man, so we may ascend to life again through a victorious one; and as through a man death received the palm [of victory] against us, so again by a man we may receive the palm against death.

2. Now the Lord would not have recapitulated in Himself that ancient and primary enmity against the serpent, fulfilling the promise of the Creator (Demiurgi), and performing His command, if He had come from another Father. But as He is one and the same, who formed us at the beginning, and sent His Son at the end, the Lord did perform His command, being made of a woman, by both destroying our adversary, and perfecting man after the image and likeness of God. And for this reason He did not draw the means of confounding him from any other source than from the words of the law, and made use of the Father's commandment as a help towards the destruction and confusion of the apostate angel. Fasting forty days, like Moses and Elias, He afterwards hungered, first, in order that we may perceive that He was a real and substantial man—for it belongs to a man to suffer hunger when fasting; and secondly, that His opponent might have an opportunity of attacking Him. For as at the beginning it was by means of food that [the enemy] persuaded man, although not suffering hunger, to transgress God's commandments, so in the end he did not succeed in persuading Him that was an hungered to take that food which proceeded from God. For, when tempting Him, he said, "If thou be the Son of God, command that these stones be made bread."⁴⁶³¹ But the Lord repulsed him by the commandment of the law, saying, "It is written, Man doth not live by bread alone."⁴⁶³² As to those words [of His enemy,] "If thou be the Son of God," [the Lord] made no remark; but by thus acknowledging His human nature He baffled His adversary, and exhausted the force of his first attack by means of His Father's word. The corruption of man, therefore, which occurred in paradise by both [of our first parents] eating, was done away with by [the Lord's] want of food in this world.⁴⁶³³ But he, being thus vanquished by the law, endeavoured again to make an assault by himself quoting a commandment of the law. For, bringing Him to the highest pinnacle of the temple, he said to Him, "If thou art the Son of God, cast thyself down. For it is written, That God shall give His angels charge concerning thee, and in their hands they shall bear thee up, lest perchance thou dash thy foot against a stone;"⁴⁶³⁴ thus concealing a falsehood under the guise of Scripture, as is done by all the heretics. For that was indeed written, [namely], "That He hath given His angels charge concerning Him;" but "cast thyself down from hence" no Scripture said in reference to Him: this kind of persuasion the devil produced from himself. The Lord therefore confuted him out of the law, when He said, "It is written again, Thou shalt not tempt the Lord thy God;"⁴⁶³⁵ pointing out by the word contained in the law that which is the duty of man, that he should not tempt God; and in regard to Himself, since He appeared in human form, [declaring] that He would not tempt the Lord his God.⁴⁶³⁶ The pride of reason, therefore, which was in the serpent, was put to nought by the humility found in the man [Christ], and now twice was the devil conquered from Scripture, when he was detected as advising things contrary to God's commandment, and was shown to be the enemy of God by [the expression of] his thoughts. He then, having been thus signally defeated, and then, as it were, concentrating his forces, drawing up in order all his available power for falsehood, in the third place "showed Him all the kingdoms of the world, and the glory of them,"⁴⁶³⁷ saying, as Luke relates, "All these will I give thee,—for they are delivered to me; and to whom I will, I give them,—if thou wilt fall down and worship me." The Lord then, exposing him in his true character, says, "Depart, Satan; for it is written, Thou shalt worship the Lord thy God, and Him only shalt thou serve."⁴⁶³⁸ He both revealed him by this name, and showed [at the same time] who He Himself was. For the Hebrew word "Satan" signifies an apostate. And thus, vanquishing him for the third time, He spurned him from Him finally as being conquered out of the law; and there was done away with that infringement of God's commandment which had occurred in Adam, by means of the precept of the law, which the Son of man observed, who did not transgress the commandment of God.

3. Who, then, is this Lord God to whom Christ bears witness, whom no man shall tempt, whom all should worship, and serve Him alone? It is, beyond all manner of doubt, that God who also gave the law. For these things had been predicted in the law, and by the words (sententiam) of the law the Lord showed that the law does indeed declare the Word of God from the Father; and the apostate angel of God is destroyed by its voice, being exposed in his true colours, and vanquished by the Son of man keeping the commandment of God. For as in the beginning he enticed man to transgress his Maker's law, and thereby got him into his power; yet his power consists in transgression and apostasy, and with these he bound man [to himself]; so again, on the other hand, it was necessary that through man himself he should, when conquered, be bound with the same chains with which he had bound man, in order that man, being set free, might return to his Lord, leaving to him (Satan) those bonds by which he himself had been fettered, that is, sin. For when Satan is bound, man is set free; since "none can enter a strong man's house and spoil his goods, unless he first bind the strong man himself."⁴⁶³⁹ The Lord therefore exposes him as speaking contrary to the word of that God who made all things, and subdues him by means of the commandment. Now the law is the commandment of God. The Man proves him to be a fugitive from and a transgressor of the law, an apostate also from God. After [the Man had done this], the Word bound him securely as a fugitive from Himself, and made spoil of his goods,—namely, those men whom he held in bondage, and whom he unjustly used for his own purposes. And justly indeed is he led captive, who had led men unjustly into bondage; while man, who had been led captive in times past, was rescued from the grasp of his possessor, according to the tender mercy of God the Father, who had compassion on His own handiwork, and gave to it salvation, restoring it by means of the Word—that is, by Christ—in order that man might learn by actual proof that he receives incorruptibility not of himself, but by the free gift of God.
