Tertullian
Excerpts from the Original Electronic Text at the web site of New Advent's Father's of the Church.

The following excerpts contain Tertullian's two most famous expressions: "what has Athens to do with Jerusalem" and it is "to be believed because it is absurd." Both expressions occurred in the context of a polemical war of words against "heretics" and perhaps give an exaggerated sense of Tertullian's distrust of the role of reason in religion. Nevertheless, they capture the essence of a Christianity grounded in faith and acutely aware that the vital tenets of Christian faith transcended reason, appearing irrational to natural reason.

Prescription Against Heretics

Chapter 1
Introduction: Heresies Must Exist, and Even Abound.

THE character of the times in which we live is such as to call forth from us even this admonition, that we ought not to be astonished at the heresies (which abound) neither ought their existence to surprise us, for it was foretold that they should come to pass; nor the fact that they subvert the faith of some, for their final cause is, by affording a trial to faith, to give it also the opportunity of being "approved." Groundless, therefore, and inconsiderate is the offence of the many who are scandalized by the very fact that heresies prevail to such a degree. How great (might their offence have been) if they had not existed. When it has been determined that a thing must by all means be, it receives the (final) cause for which it has its being. This secures the power through which it exists, in such a way that it is impossible for it not to have existence. . . .

Chapter 3
Weak People Fall an Easy Prey to Heresy

It is usual, indeed, with persons of a weaker character, to be so built up (in confidence) by certain individuals who are caught by heresy, as to topple over into ruin themselves. How comes it to pass, (they ask), that this woman or that man, who were the most faithful, the most prudent, and the most approved in the church, have gone over to the other side? Who that asks such a question does not in fact reply to it himself, to the effect that men whom heresies have been able to pervert ought never to have been esteemed prudent, or faithful, or approved? This again is, I suppose, an extraordinary thing, that one who has been approved should afterwards fall back? Saul, who was good beyond all others, is afterwards subverted by envy. David, a good man "after the Lord's own heart," is guilty afterwards of murder and adultery. Solomon, endowed by the Lord with all grace and wisdom, is led into idolatry, by women. For to the Son of God alone was it reserved to persevere to the last without sin. But what if a bishop, if a deacon, if a widow, if a virgin, if a doctor, if even a martyr, have fallen from the rule (of faith), will heresies on that account appear to possess the truth? Do we prove the faith by the persons, or the persons by the faith? No one is wise, no one is faithful, no one excels in dignity, but the Christian; and no one is a Christian but he who perseveres even to the end. You, as a man, know any other man from the outside appearance. You think as you see. And you see as far only as you have eyes. But says (the Scripture), "the eyes of the Lord are lofty." "Man looketh at the outward appearance, but God looketh at the heart." "The Lord (beholdeth and) knoweth them that are His;" and "the plant which (my heavenly Father) hath not planted, He rooteth up;" and "the first shall," as He shows, "be last;" and He carries "His fan in His hand to purge His threshing-floor." Let the chaff of a fickle faith fly off as much as it will at every blast of temptation, all the purer will be that heap of corn which shall be laid up in the garner of the Lord. Did not certain of the disciples turn back from the Lord Himself, When they were offended? Yet the rest did not therefore think that they must turn away from following Him, but because they knew that He was the Word of Life, and was come from God, they continued in His company to the very last, after He had gently inquired of them whether they also would go away. It is a comparatively small thing, that certain men, like Phygellus, and Hermogenes, and Philetus, and Hymenaeus, deserted His apostle: the betrayer of Christ was himself one of the apostles. We are surprised at seeing His churches forsaken by some men, although the things which we suffer after the example of Christ Himself, show us to be Christians. "They went out from us," says (St. John,) "but they were not of us. If they had been of us, they would no doubt have continued with us."

Chapter 6
Heretics are Self-Condemned.
Heresy is Self-Will, While Faith is Submission of Our Will to Divine Authority

On this point, however, we dwell no longer, since it is the same Paul who, in his Epistle to the Galatians, counts "heresies" among "the sins of the flesh," who also intimates to Titus, that "a man who is a heretic" must be "rejected after the first admonition," on the ground that "he that is such is perverted, and committeth sin, as a self-condemned man." Indeed, in almost every epistle, when enjoining on us (the duty) of avoiding false doctrines, he sharply condemns heresies. Of these the practical effects are false doctrines, called in Greek heresies, a word used in the sense of that choice which a man makes when he either teaches them (to others) or takes up with them (for himself). For this reason it is that he calls the heretic condemned, because he has himself chosen that for which he is condemned. We, however, are not permitted to cherish any object after our own will, nor yet to make choice of that which another has introduced of his private fancy. In the Lord's apostles we possess our authority; for even they did not of themselves choose to introduce anything, but faithfully delivered to the nations (of mankind) the doctrine which they had received from Christ. If, therefore, even "an angel from heaven should preach any other gospel" (than theirs), he would be called accursed by us. The Holy Ghost had even then foreseen that there would be in a certain virgin (called) Philumene an angel of deceit, "transformed into an angel of light," by whose miracles and illusions Apelles was led (when) he introduced his new heresy.

Chapter 7
Pagan Philosophy the Parent of Heresies
The Connection between Deflections from Christian Faith and the Old Systems of Pagan Philosophy

These are "the doctrines" of men and "of demons" produced for itching ears of the spirit of this world's wisdom: this the Lord called "foolishness," and "chose the foolish things of the world" to confound even philosophy itself. For (philosophy) it is which is the material of the world's wisdom, the rash interpreter of the nature and the dispensation of God. Indeed heresies are themselves instigated by philosophy. From this source came the AEons, and I known not what infinite forms, and the trinity of man in the system of Valentinus, who was of Plato's school. From the same source came Marcion's better god, with all his tranquillity; he came of the Stoics. Then, again, the opinion that the soul dies is held by the Epicureans; while the denial of the restoration of the body is taken from the aggregate school of all the philosophers; also, when matter is made equal to God, then you have the teaching of Zeno; and when any doctrine is alleged touching a god of fire, then Heraclitus comes in. The same subject-matter is discussed over and over again by the heretics and the philosophers; the same arguments are involved. Whence comes evil? Why is it permitted? What is the origin of man? and in what way does he come? Besides the question which Valentinus has very lately proposed--Whence comes God? Which he settles with the answer: From enthymesis and ectroma. Unhappy Aristotle! who invented for these men dialectics, the art of building up and pulling down; an art so evasive in its propositions, so far-fetched in its conjectures, so harsh, in its arguments, so productive of contentions--embarrassing even to itself, retracting everything, and really treating of nothing! Whence spring those "fables and endless genealogies," and "unprofitable questions," and "words which spread like a cancer?" From all these, when the apostle would restrain us, he expressly names philosophy as that which he would have us be on our guard against. Writing to the Colossians, he says, "See that no one beguile you through philosophy and vain deceit, after the tradition of men, and contrary to the wisdom of the Holy Ghost." He had been at Athens, and had in his interviews (with its philosophers) become acquainted with that human wisdom which pretends to know the truth, whilst it only corrupts it, and is itself divided into its own manifold heresies, by the variety of its mutually repugnant sects. What indeed has Athens to do with Jerusalem? What concord is there between the Academy and the Church? what between heretics and Christians? Our instruction comes from "the porch of Solomon," who had himself taught that "the Lord should be sought in simplicity of heart."

Away with all attempts to produce a mottled Christianity of Stoic, Platonic, and dialectic composition! We want no curious disputation after possessing Christ Jesus, no inquisition after enjoying the gospel! With our faith, we desire no further belief. For this is our palmary faith, that there is nothing which we ought to believe besides.



On the Flesh of Christ

Chapter 4
God's Honor in the Incarnation of His Son Vindicated

Since, therefore, you do not reject the assumption of a body' as impossible or as hazardous to the character of God, it remains for you to repudiate and censure it as unworthy of Him. Come now, beginning from the nativity itself, declaim against the uncleanness of the generative elements within the womb, the filthy concretion of fluid and blood, of the growth of the flesh for nine: months long out of that very mire. Describe the womb as it enlarges from day to day,heavy, troublesome, restless even in sleep, changeful in its feelings of dislike and desire. Inveigh now likewise against the shame itself of a woman in travail which, however, ought rather to be honoured in consideration of that peril, or to be held sacred in respect of (the mystery of) nature. Of course you are horrified also at the infant, which is shed into life with the embarrassments which accompany it from the womb; you likewise, of course, loathe it even after it is washed, when it is dressed out in its swaddling-clothes, graced with repeated anointing, smiled on with nurse's fawns. This reverend course of nature, you, O Marcion, (are pleased to) spit upon; and yet, in what way were you born? You detest a human being at his birth; then after what fashion do you love anybody? Yourself, of course, you had no love of, when you departed from the Church and the faith of Christ. But never mind? if you are not on good terms with yourself, or even if you were born in a way different from other people. Christ, at any rate, has loved even that man who was condensed in his mother's womb amidst all its uncleannesses, even that man who was brought into life out of the said womb, even that man who was nursed amidst the nurse's simpers. For his sake He came down (from heaven), for his sake He preached, for his sake "He humbled Himself even unto death--the death of the cross." He loved, of course, the being whom He redeemed at so great a cost. If Christ is the Creator's Son, it was with justice that He loved His own (creature); if He comes from another god, His love was excessive, since He redeemed a being who belonged to another. Well, then, loving man He loved his nativity also, and his flesh as well. Nothing can be loved apart from that through which whatever exists has its existence. Either take away nativity, and then show us your man; or else withdraw the flesh, and then present to our view the being whom God has redeemed--since it is these very conditions which constitute the man whom God has redeemed. And are you for turning these conditions into occasions of blushing to the very creature whom He has redeemed, (censuring them), too, us unworthy of Him who certainly would not have redeemed them had He not loved them? Our birth He reforms from death by a second birth from heaven; our flesh He restores from every harassing malady; when leprous, He cleanses it of the stain; when blind, He rekindles its light; when palsied, He renews its strength; when possessed with devils, He exorcises it; when dead, He reanimates it,--then shall we blush to own it? If, to be sure, He had chosen to be born of a mere animal, and were to preach the kingdom of heaven invested with the body of a beast either wild or tame, your censure (I imagine) would have instantly met Him with this demurrer: "This is disgraceful for God, and 'this is unworthy of the Son of God, and simply foolish." For no other reason than because one thus judges. It is of course foolish, if we are to judge God by our own conceptions. But, Marcion, consider well this Scripture, if indeed you have not erased it: "God hath chosen the foolish things of the world, to confound the wise." Now what are those foolish things? Are they the conversion of men to the worship of the true God, the rejection of error, the whole training in righteousness, chastity, mercy, patience, and innocence? These things certainly are not "foolish." Inquire again, then, of what things he spoke, and when you imagine that you have discovered what they are will you find anything to be so "foolish" as believing in a God that has been born, and that of a virgin, and of a fleshly nature too, who wallowed in all the before-mentioned humiliations of nature?

But some one may say, "These are not the foolish things; they must be other things which God has chosen to confound the wisdom of the world." And yet, according to the world's wisdom, it is more easy to believe that Jupiter became a bull or a swan, if we listen to Marcion, than that Christ really became a man.

Chapter 5
Christ Truly Lived and Died in Human Flesh

There are, to be sure, other things also quite as foolish (as the birth of Christ), which have reference to the humiliations and sufferings of God. Or else, let them call a crucified God "wisdom." But Marcion will apply the knife' to this doctrine also,, and even with greater reason. For which Is more unworthy of God, which is more likely to raise a blush of shame, that God should be born, or that He should die? that He should bear the flesh, or the cross? be circumcised, or be crucified? be cradled, or be coffined? be laid in a manger, or in a tomb? Talk of "wisdom!" You will show more of fiat if you refuse to believe this also. But, after all, you will not be "wise" unless you become a "fool" to the world, by believing" the foolish things of God."

Have you, then, cut away all sufferings from Christ, on the ground that, as a mere phantom, He was incapable of experiencing them? We have said above that He might possibly have undergone the unreal mockeries of an imaginary birth and infancy. But answer me at once, you that murder truth: Was not God really crucified? And, having been really crucified, did He not really die? And, having indeed really died, did He not really rise again? Falsely did Paul "determine to know nothing amongst us but Jesus and Him crucified; falsely has he impressed upon us that He was buried; falsely inculcated that He rose again. False, therefore, is our faith also. And all that we hope for from Christ will be a phantom. O thou most infamous of men, who acquittest of all guilt the murderers of God! For nothing did Christ suffer from them, if He really suffered nothing at all. Spare the whole world's one only hope, thou who art destroying the indispensable dishonour of our faith? Whatsoever is unworthy of God, is of gain to me. I am safe, if I am not ashamed--my Lord.

"Whosoever," says He, "shall be ashamed of me, of him will I also be ashamed." Other matters for shame find I none which can prove me to be shameless in a good sense, and foolish in a happy one, by my own contempt of shame. The Son of God was crucified; I am not ashamed because men must needs be ashamed of it. And the Son of God died; it is by all means to be believed, because it is absurd. And He was buried, and rose again; the fact is certain, because it is impossible. But how will all this be true in Him, if He was not Himself true--if He really had not in Himself that which might be crucified, might die, might be buried, and might rise again? I mean this flesh suffused with blood, built up with bones, interwoven with nerves, entwined with veins, a flesh which knew how to be born, and how to die, human without doubt, as born of a human being. It will therefore be mortal in Christ, because Christ is man and the Son of man. Else why is Christ man and the Son of man, if he has nothing of man, and nothing from man? Unless it be either that man is anything else than flesh, or man's flesh comes from any other source than man, or Mary is anything else than a human being, or Marcion's man is as Marcion's god. Otherwise Christ could not be described as being man without flesh, nor the Son of man without any human parent; just as He is not God without the Spirit of God, nor the Son of God without having God for His father. Thus the nature of the two substances displayed Him as man and God,--in one respect born, in the other unborn; I in one respect fleshly in the other spiritual; in one sense weak in the other exceeding strong; in on sense dying, in the other living. This property of the two states--the divine and the human--is distinctly asserted with equal truth of both natures alike, with the same belief both in respect of the Spirit '* and of the flesh. The powers of the Spirit, proved Him to be God, His sufferings attested the flesh of man. If His powers were not without the Spirit in like manner, were not His sufferings without the flesh. if His flesh with its sufferings was fictitious, for the same reason was the Spirit false with all its powers. Wherefore halve Christ with a lie? He was wholly the truth. Believe me, He chose rather to be born, than in any part to pretend--and that indeed to His own detriment--that He was bearing about a flesh hardened without bones, solid without muscles, bloody without blood, clothed without the tunic of skin, hungry without appetite, eating without teeth, speaking without a tongue, so that His word was a phantom to the ears through an imaginary voice. A phantom, too, it was of course after the resurrection, when, showing His hands and His feet for the disciples to examine, He said, "Behold and see that it is I myself, for a spirit hath not flesh and bones, as ye see me have;" without doubt, hands, and feet, and bones are not what a spirit possesses, but only the flesh. How do you interpret this statement, Marcion, you who tell us that Jesus comes only from the most excellent God, who is both simple and good? See how He rather cheats, and deceives, and juggles the eyes of all, and the senses of all, as well as their access to and contact with Him! You ought rather to have brought Christ down, not from heaven, but from some troop of mountebanks, not as God besides man, but simply as a man, a magician; not as the High Priest of our salvation, but as the conjurer in a show; not as the raiser of the dead, but as the misleader of the living,--except that, if He were a magician, He must have had a nativity!
