Morality in Marriage

The Morality of Venereal Acts of Marriage.—(a) Non-consummated Acts.—These acts, whether internal or external, are lawful per se when they are used only as accessories to the act of marriage or as means to foster or preserve conjugal love, for the acts are meant by God to serve the purposes mentioned (2510). But per accidens there may be venial sin, on account of inordinateness in the motive (i.e., when only pleasure is intended), or in the manner (i.e., when due decency is not observed). There is mortal sin when these acts are not referred to the lawful conjugal act, but either directly or indirectly to pollution, namely, when there is foreseen proximate danger of pollution and the acts are either solitary or cooperative but performed without sufficient reason (such as expressions of special affection), for pollution is gravely sinful in the married, as well as in the single state (see 2539 sqq.).

(b) Natural Consummated Act.—This act in itself is not only lawful, but meritorious, because it exercises such virtues as obedience (Gen., i. 28), justice (I Cor., vii. 3 sqq.), and love of the common good and religion (Tob., viii. 9). Since marriage intercourse has for its ends not only reproduction, but also the expression of mutual love and the allaying of concupiscence, it is lawful even when conception is impossible or less probable, as when the parties are sterile, or the woman is pregnant, or during the so-called agenesic period, or at the time of lactation. It is a venial sin to exercise the conjugal act when one excludes every motive except that of pleasure (Denziger, n. 1159); and there may be even mortal sin on account of circumstances, such as place (e.g., scandal to others present), manner (e.g., external immoderation, internal desire of another person), evil consequences (e.g., when one of the parties has a contagious or veneral disease, when abortion will likely result, etc.).

(c) Unnatural Consummated Acts.—Pollution is mortally sinful (2535 sqq.), and is worse in married than in single persons, as being an injury to the faith pledged in marriage; and hence it is not lawful to practise it even for the purpose of artificial fecundation. Rectal copulation is also gravely sinful, being unnatural lust (see 2534) and a violation of conjugal faith. The usual forms of unnatural vaginal coition, which are very much practised today, are contraceptive in purpose, and are of two general kinds in the procedure—the physiological or preventive, which uses instruments to keep the semen from the uterus (such as sponges or pessaries for the female, condoms or protectors for the male), or which employs douches or syringes to remove semen from the vagina, or uses chemicals to devitalize it.

Nota.—(a) Non habetur onanismus, nec peccatum, si copula abrumpitur, ex necessitate (v.g., ad vitandum scandalum persona inopinate supervenientis), vel ex utilitate, mutuo dato consensu et periculo pollutionis excluso; nam seminatio extra vas, aut involuntaria est, aut nulla.

(b) Non habetur contraceptio nec peccatum, sed potius actus honestus, si, ob defectum physicum viri vel mulieris, naturae adjuvetur mediis artificialibus ut copula fiat, vel ut semen introducatur in uterum; nam fini matrimonii non obstat, sed obsecundat iste modus agendi.

(c) Artificial Insemination. The subject-matter of the latter part of the preceding paragraph is distinguished from several unlawful practices considered by moralists under the heading of artificial insemination. Pope Pius XII on several occasions has given a clear, accurate and complete statement of Catholic teaching on the subject. We append here his texts:

1. The practice of artificial insemination, when it refers to man, cannot be considered, either exclusively or principally, from the biological and medical point of view, ignoring the moral and legal one.

Artificial insemination, outside of marriage, must be condemned as essentially and strictly immoral.

Natural law and divine positive law establish, in fact, that the procreation of a new life cannot but be the fruit of marriage. Only marriage safeguards the dignity of the spouses (principally of the wife in the present case) and their personal good. It alone provides for the well-being and education of the child.

It follows that no divergence of opinion among Catholics is admitted on the condemnation of artificial insemination outside of marriage. The child conceived in those conditions would be, by that very fact, illegitimate.

Artificial insemination produced in a marriage by the active element of a third party is equally immoral and consequently to be condemned without appeal.

Only the spouses have a reciprocal right upon each other’s body to generate a new life: an exclusive, inalienable right, which cannot be ceded. And so it must be, even out of consideration for the child. On whoever gives life to a small being, nature imposes, by the very strength of that tie, the duty to keep and educate it. But no ties of origin, no moral or legal bonds of conjugal procreation, exist between the legitimate husband and the child who is the fruit of the active element of a third party (even if the husband has given his consent).

As far as the legitimacy of artificial insemination in marriage is concerned, it suffices, for the moment, to recall these principles of natural law: the simple fact that the result desired is obtained by this means does not justify the use of the means itself; nor does the desire of the husband and wife, in itself perfectly legitimate, to have a child, suffice to establish the legitimacy of resorting to the artificial insemination which would satisfy this desire.

It would be erroneous, therefore, to think that the possibility of resorting to this means might render valid a marriage between persons unable to contract it because of the impedimentum impotentiae.

On the other hand, it is superfluous to mention that the active element can never be obtained legitimately by means of acts against nature.

Although new methods cannot be ruled out a priori for the sole reason of their novelty, nonetheless, as far as artificial impregnation is concerned, extreme caution is not enough; it must be absolutely excluded. Saying this does not necessarily proscribe the use of certain artificial means destined only to facilitate the natural act, or to assure the accomplishment of the end of the natural act regularly performed.

Let it never be forgotten that only the procreation of a new life according to the will and the designs of the Creator brings with it, to a marvelous degree of perfection, the accomplishment of the proposed ends. It is at the same time in conformity with corporeal and spiritual nature and the dignity of the married couple, as well as with the healthy, normal development of the child (Address to Physicians, Sept. 29, 1949, Discorsi e Radiomessaggi, vol. xi, pp. 221 ff).

2. We also believe that it is of capital importance for you, gentlemen, not to neglect this perspective when you consider the methods of artificial fecundation. The means by which one tends toward the production of a new life take on an essential human significance inseparable from the desired end and susceptible of causing grave harm to this very end if these means are not conformable to reality and to the laws inscribed in the nature of beings.

We have been asked to give some directives on this point also. On the subject of the experiments in artificial human fecundation “in vitro,” let it suffice for Us to observe that they must be rejected as immoral and absolutely illicit. With regard to the various moral problems which are posed by artificial fecundation, in the ordinary meaning of the expression, or “artificial insemination,” We have already expressed Our thought in a discourse addressed to physicians on September 29, 1949 (Discorsi e Radiomessaggi, vol. xi. pp. 221 ff.). For the details We refer you to what We said then and We confine Ourself here to repeating the concluding judgment given there: “With regard to artificial fecundation, not only is there reason to be extremely reserved, but it must be absolutely rejected. In speaking thus, one is not necessarily forbidding the use of certain artificial means destined solely to facilitate the natural act or to achieve the attainment of the natural act normally performed.” But since artificial fecundation is being more and more widely used, and in order to correct some erroneous opinions which are being spread concerning what We have taught, We have the following to add:

Artificial fecundation exceeds the limits of the right which spouses have acquired by the matrimonial contract, namely, that of fully exercising their natural sexual capacity in the natural accomplishment of the marital act. The contract in question does not confer on them a right to artificial fecundation, for such a right is not in any way expressed in the right to the natural conjugal act and cannot be deduced from it. Still less can one derive it from the right to the “child,” the primary “end” of marriage. The matrimonial contract does not give this right, because it has for its object not the “child,” but the “natural acts” which are capable of engendering a new life and are destined to this end. It must likewise be said that artificial fecundation violates the natural law and is contrary to justice and morality [1] (Marriage and Parenthood, May 19, 1956). See The Pope Speaks, Vol, III, No. 2, Autumn of 1956, pp. 194 ff.

[1] The Holy Father here spoke for several minutes in Latin as follows:

Alia nunc occurrit quaestio, ad quam pertractandam magis addecet latinam linguam adhibere.

Quemadmodum rationalis animus noster artificiali inseminationi adversatur, ita eadem ethica ratio, a qua agendi normo sumenda est, pariter vetat, quominus humanum semen, peritorum examini subiciendum, masturbatiouis ope procuretur.

Hanc agendi rationem attigimus Nostra quoque allocutione coram Urologiae doctoribus coetum participantibus, die VIII mensis Octobris anno MDCCCCLIII prolata, in qua haec habuimus, verba: “Du reste le St-Office a decide deja le 2 aout 1929 (Acta Ap. Sedis, vol. XXI a. 1929, p. 490, II) qu’une “‘masturbatio directe procurata ut obtineatur sperma’ n’est pas licite, ceci quel que soit le but de l’examen” (Discorsi e Radiomessaggi vol. XV, pag. 378). Cum vero Nobis allatum sit, pravam huiusmodi consuetudinem pluribus in locis invalescere, opportunum ducimus nunc etiam, quae tunc monuimus, commemorare atque iterum inculcare.

Si actus huiusmodi ad explendam libidinem ponantur, eos vel ipse naturalis hominis sensus sua sponte respuit, ac multo magis mentis iudicium, quotiescumque rem mature recteque considerat. Iidem actus tamen tunc quoque respuendi sunt, cum graves rationes eos a culpa eximere videntur, uti sunt: remedia iis praestanda qui nimia nervorum intentione vel abnormibus animi spasmis laborant; medicis peragenda, ope microscopii, spermatis inspectio, quod venerei vel alius generis morbi bacteriis infectum sit; diversarum partium examen, ex quibus semen ordinarie constat, ut vitalium spermatis elementorum praesentia, numerus, quantitus, forma, vis, habitus aliaque id genus dignoscuntur.

Eiusmodi procuratio humani seminis, per masturbationem effecta, ad nihil aliud directe spectat, nisi ad naturalem in homine generandi facultatem plene exercendam; quod quidem plenum exercitium, extra conjugalem copulam peractum, secum fert directum et indebite usurpatum eiusdem facultatis usum. In hoc eiusmodi indebito facultatis usu proprie sita est intrinseca regulae morum violatio. Haudquaquam enim homo ius ullum exercendi facultatem sexualem iam inde habet, quod facultatem eandem a natura recepit. Homini nempe (secus ac in ceteris animantibus rationis expertibus contingit) ius et potestas utendi atque exercendi eandem facultatem tantummodo in nuptiis valide initis tribuitut, atque in iure matrimoniali continetur, quod ipsis nuptiis traditur et acceptatur. Inde elucet hominem, ob solam hanc causam quod facultatem sexualem a natura recepit, non habere nisi potentiam et ius ad matrimonium ineundum. Hoc ius tamen, ad objectum et ambitum quod attinet, naturae lege, non hominum voluntate discribitur; vi huius legis naturae, homini non competit ius et potestas ad plenum facultatis sexualis exercitium, directe intentum, nisi cum coniugalem copulam exercet ad normam a natura ipsa imperatam atque definitam. Extra hunc naturalem actum, ne in ipso quidem matrimonio ius datur ad sexuali hac facultate plene fruendum. Hi sunt limites, quibus ius, de quo diximus, eiusque exercitium a natura circumscribuntur. Ex eo quod plenum sexualis facultatis exercitium hoc absolute copulae coniugalis limite circumscribitur, eadem facultas intrinsece apta efficitur ad plenum matrimonii naturalem finem assequendum (qui non modo est generatio, sed etiam prolis educatio), atque eius exercitum cum dicto fine colligatur. Quae cum ita sint, masturbatio omnino est extra memoratam pleni facultatis sexualis exercitii naturalem habilitatem, ideoque etiam extra eius colligationem cum fine a natura ordinato; quamobrem eadem omni iuris titulo caret atque naturae et ethices legibus contraria est, etiamsi inservire intendat utilitati per se iustae nec improbandae.

Quae hactenus dicta sunt de intrinseca malitia cuiuslibet pleni usus potentiae generandi extra naturalem coniugalem copulam, valent eodem modo cum agitur de matrimonio iunctis vel de matrimonio solutis, sive plenum exercitium apparatus genitalis fit a viro sive a muliere, sive ab utraque parte simul agente; sive fit tactibus manualibus sive coniugalis copulae interruptione; haec enim semper est actus naturae contrarius atque intrinsece malus.
