Summa Theologica by Saint Thomas Aquinas (whitelam books .TXT) 📕

the greatest of virtues, but only in comparison with other degrees of chastity.

Reply Obj. 3: Virgins "follow the Lamb whithersoever He goeth," because they imitate Christ, by integrity not only of the mind but also of the flesh, as Augustine says (De Virgin. xxvii). Wherefore they follow the Lamb in more ways, but this does not imply that they follow more closely, because other virtues make us cleave to God more closely by imitation of the mind. The "new hymn" which virgins alone sing, is their joy at having preserved integrity of the flesh. _______________________

QUESTION 153

OF LUST
(In Five Articles)

We must next consider the vice of lust which is opposed to chastity: (1) Lust in general; (2) its species. Under the first head there are five points of inquiry:

(1) What is the matter of lust?

(2) Whether all copulation is unlawful?

(3) Whether lust is a mortal sin?

(4) Whether lust is a capital vice?

(5) Concerning its daughters. _______________________

FIRST ARTICLE [II-II, Q. 153, Art. 1]

Whether the Matter of Lust Is Only Venereal Desires and Pleasures?

Objection 1: It would seem that the matter of lust is not only venereal desires and pleasures. For Augustine says (Confess. ii, 6) that "lust affects to be called surfeit and abundance." But surfeit regards meat and drink, while abundance refers to riches. Therefore lust is not properly about venereal desires and pleasures.

Obj. 2: Further, it is written (Prov. 20:1): "Wine is a lustful [Douay: 'luxurious'] thing." Now wine is connected with pleasure of meat and drink. Therefore these would seem to be the matter of lust.

Obj. 3: Further, lust is defined "as the desire of wanton pleasure" [*Alexander of Hales, Summ. Theol. ii, cxvli]. But wanton pleasure regards not only venereal matters but also many others. Therefore lust is not only about venereal desires and pleasures.

On the contrary, To the lustful it is said (De Vera Relig. iii [*Written by St. Augustine]): "He that soweth in the flesh, of the flesh shall reap corruption." Now the sowing of the flesh refers to venereal pleasures. Therefore these belong to lust.

I answer that, As Isidore says (Etym. x), "a lustful man is one who is debauched with pleasures." Now venereal pleasures above all debauch a man's mind. Therefore lust is especially concerned with such like pleasures.

Reply Obj. 1: Even as temperance chiefly and properly applies to pleasures of touch, yet consequently and by a kind of likeness is referred to other matters, so too, lust applies chiefly to venereal pleasures, which more than anything else work the greatest havoc in a man's mind, yet secondarily it applies to any other matters pertaining to excess. Hence a gloss on Gal. 5:19 says "lust is any kind of surfeit."

Reply Obj. 2: Wine is said to be a lustful thing, either in the sense in which surfeit in any matter is ascribed to lust, or because the use of too much wine affords an incentive to venereal pleasure.

Reply Obj. 3: Although wanton pleasure applies to other matters, the name of lust has a special application to venereal pleasures, to which also wantonness is specially applicable, as Augustine remarks (De Civ. xiv, 15, 16). _______________________

SECOND ARTICLE [II-II, Q. 153, Art. 2]

Whether No Venereal Act Can Be Without Sin?

Objection 1: It would seem that no venereal act can be without sin. For nothing but sin would seem to hinder virtue. Now every venereal act is a great hindrance to virtue. For Augustine says (Soliloq. i, 10): "I consider that nothing so casts down the manly mind from its height as the fondling of a woman, and those bodily contacts." Therefore, seemingly, no venereal act is without sin.

Obj. 2: Further, any excess that makes one forsake the good of reason is sinful, because virtue is corrupted by "excess" and "deficiency" as stated in Ethic. ii, 2. Now in every venereal act there is excess of pleasure, since it so absorbs the mind, that "it is incompatible with the act of understanding," as the Philosopher observes (Ethic. vii, 11); and as Jerome [*Origen, Hom. vi in Num.; Cf. Jerome, Ep. cxxiii ad Ageruch.] states, rendered the hearts of the prophets, for the moment, insensible to the spirit of prophecy. Therefore no venereal act can be without sin.

Obj. 3: Further, the cause is more powerful than its effect. Now original sin is transmitted to children by concupiscence, without which no venereal act is possible, as Augustine declares (De Nup. et Concup. i, 24). Therefore no venereal act can be without sin.

On the contrary, Augustine says (De Bono Conjug. xxv): "This is a sufficient answer to heretics, if only they will understand that no sin is committed in that which is against neither nature, nor morals, nor a commandment": and he refers to the act of sexual intercourse between the patriarchs of old and their several wives. Therefore not every venereal act is a sin.

I answer that, A sin, in human acts, is that which is against the order of reason. Now the order of reason consists in its ordering everything to its end in a fitting manner. Wherefore it is no sin if one, by the dictate of reason, makes use of certain things in a fitting manner and order for the end to which they are adapted, provided this end be something truly good. Now just as the preservation of the bodily nature of one individual is a true good, so, too, is the preservation of the nature of the human species a very great good. And just as the use of food is directed to the preservation of life in the individual, so is the use of venereal acts directed to the preservation of the whole human race. Hence Augustine says (De Bono Conjug. xvi): "What food is to a man's well being, such is sexual intercourse to the welfare of the whole human race." Wherefore just as the use of food can be without sin, if it be taken in due manner and order, as required for the welfare of the body, so also the use of venereal acts can be without sin, provided they be performed in due manner and order, in keeping with the end of human procreation.

Reply Obj. 1: A thing may be a hindrance to virtue in two ways. First, as regards the ordinary degree of virtue, and as to this nothing but sin is an obstacle to virtue. Secondly, as regards the perfect degree of virtue, and as to this virtue may be hindered by that which is not a sin, but a lesser good. In this way sexual intercourse casts down the mind not from virtue, but from the height, i.e. the perfection of virtue. Hence Augustine says (De Bono Conjug. viii): "Just as that was good which Martha did when busy about serving holy men, yet better still that which Mary did in hearing the word of God: so, too, we praise the good of Susanna's conjugal chastity, yet we prefer the good of the widow Anna, and much more that of the Virgin Mary."

Reply Obj. 2: As stated above (Q. 152, A. 2, ad 2; I-II, Q. 64, A. 2), the mean of virtue depends not on quantity but on conformity with right reason: and consequently the exceeding pleasure attaching to a venereal act directed according to reason, is not opposed to the mean of virtue. Moreover, virtue is not concerned with the amount of pleasure experienced by the external sense, as this depends on the disposition of the body; what matters is how much the interior appetite is affected by that pleasure. Nor does it follow that the act in question is contrary to virtue, from the fact that the free act of reason in considering spiritual things is incompatible with the aforesaid pleasure. For it is not contrary to virtue, if the act of reason be sometimes interrupted for something that is done in accordance with reason, else it would be against virtue for a person to set himself to sleep. That venereal concupiscence and pleasure are not subject to the command and moderation of reason, is due to the punishment of the first sin, inasmuch as the reason, for rebelling against God, deserved that its body should rebel against it, as Augustine says (De Civ. Dei xiii, 13).

Reply Obj. 3: As Augustine says (De Civ. Dei xiii, 13), "the child, shackled with original sin, is born of fleshly concupiscence (which is not imputed as sin to the regenerate) as of a daughter of sin." Hence it does not follow that the act in question is a sin, but that it contains something penal resulting from the first sin. _______________________

THIRD ARTICLE [II-II, Q. 153, Art. 3]

Whether the Lust That Is About Venereal Acts Can Be a Sin?

Objection 1: It would seem that lust about venereal acts cannot be a sin. For the venereal act consists in the emission of semen which is the surplus from food, according to the Philosopher (De Gener. Anim. i, 18). But there is no sin attaching to the emission of other superfluities. Therefore neither can there be any sin in venereal acts.

Obj. 2: Further, everyone can lawfully make what use he pleases of what is his. But in the venereal act a man uses only what is his own, except perhaps in adultery or rape. Therefore there can be no sin in venereal acts, and consequently lust is no sin.

Obj. 3: Further, every sin has an opposite vice. But, seemingly, no vice is opposed to lust. Therefore lust is not a sin.

On the contrary, The cause is more powerful than its effect. Now wine is forbidden on account of lust, according to the saying of the Apostle (Eph. 5:18), "Be not drunk with wine wherein is lust [Douay: 'luxury']." Therefore lust is forbidden.

Further, it is numbered among the works of the flesh: Gal. 5:19
[Douay: 'luxury'].

I answer that, The more necessary a thing is, the more it behooves one to observe the order of reason in its regard; wherefore the more sinful it becomes if the order of reason be forsaken. Now the use of venereal acts, as stated in the foregoing Article, is most necessary for the common good, namely the preservation of the human race. Wherefore there is the greatest necessity for observing the order of reason in this matter: so that if anything be done in this connection against the dictate of reason's ordering, it will be a sin. Now lust consists essentially in exceeding the order and mode of reason in the matter of venereal acts. Wherefore without any doubt lust is a sin.

Reply Obj. 1: As the Philosopher says in the same book (De Gener. Anim. i, 18), "the semen is a surplus that is needed." For it is said to be superfluous, because it is the residue from the action of the nutritive power, yet it is needed for the work of the generative power. But the other superfluities of the human body are such as not to be needed, so that it matters not how they are emitted, provided one observe the decencies of social life. It is different with the emission of semen, which should be accomplished in a manner befitting the end for which it is needed.

Reply Obj. 2: As the Apostle says (1 Cor. 6:20) in speaking against lust, "You are bought with a great price: glorify and bear God in your body." Wherefore by inordinately using the body through lust a man wrongs God Who is the Supreme Lord of our body. Hence Augustine says (De Decem. Chord. 10 [*Serm. ix (xcvi de Temp.)]): "God Who thus governs His servants for their good, not for His, made this order and commandment, lest unlawful pleasures should destroy His temple which thou hast begun to be."

Reply Obj. 3: The opposite of lust is not found in many, since men are more inclined to pleasure. Yet the contrary vice is comprised under insensibility, and occurs in one who has such a dislike for sexual intercourse as not to pay the marriage debt. _______________________

FOURTH ARTICLE [II-II, Q. 153, Art. 4]

Whether Lust Is a Capital Vice?

Objection 1: It seems that lust is not a capital vice. For lust is apparently the same as "uncleanness," according to a gloss on Eph. 5:3 (Cf. 2 Cor. 12:21). But uncleanness is a daughter of gluttony, according to Gregory (Moral. xxxi, 45). Therefore lust is not a capital vice.

Obj. 2: Further, Isidore says (De Summo Bono ii, 39) that "as pride of mind leads to the depravity of lust, so does humility of mind safeguard the chastity of the flesh." Now it is seemingly contrary to the nature of a capital vice to arise from another vice. Therefore lust is not a capital
