The Latin title of this Apostolic Exhortation by Pope Francis means “The Joy of Love”. But it is also titled, in English, “On Love in the Family”. The exhortation is termed “post-synodal” because it represents the last document of the 2015 Synod of Bishops on the Family. The document is lengthy and will take some time for the faithful to study and understand. I will offer some comments in a series of short posts on select sections of the document.
 Cf. Paul VI, Encyclical Letter Humanae Vitae (25 July 1968), 11-12: AAS 60 (1968), 488-489.
In discussions, articles, and posts online, some Catholics have contended that a husband and wife might possibly use a condom, for a good purpose, such as to prevent disease transmission, absent any contraceptive intention, especially in cases where the couple cannot conceive for various reasons (e.g. pregnancy, old age).
My understanding, to the contrary, is that each and every sexual act of the spouses must be open to life. What makes the use of contraception intrinsically evil is not a contraceptive intention, but rather the intentional (deliberate, voluntary, knowing) choice of an act inherently ordered to thwart the procreative meaning of sexual acts. The moral nature of every act of contraception is inherently morally disordered. Therefore, the deliberate choice to commit an act of contraception is always gravely immoral, regardless of intention. A contraceptive intention makes the act more gravely immoral. But a good intention, and a dire circumstance, cannot change the moral nature of the act.
Humanae Vitae teaches this rather clearly:
Thus “each and every marital act”, meaning each sexual act in a marriage, “must of necessity retain its intrinsic relationship to the procreation of human life.” And this assertion is preceded by an acknowledgment that sometimes marital relations is “foreseen to be infertile”. Therefore, the teaching that each act must in principle retain its ordering toward the procreative meaning still applies when the couple are infertile. And the doctrine specifies that they are infertile “independent of their will” because the deliberate knowing choice of an act of contraception or (direct) sterilization is intrinsically evil and always gravely immoral.
The phrasing that Pope Francis uses in Amoris Laetitia repeats and clarifies this same doctrine: “Hence no genital act of husband and wife can refuse this meaning, even when for various reasons it may not always in fact beget a new life.”
This plain and clear doctrine, which admits of no exceptions, is currently under attack by unfaithful Catholics. In truth, contraception remains gravely immoral, even when the couple are infertile due to pregnancy or old age. For intrinsically evil acts are not justified by a good intention (such as to prevent disease transmission), nor by the circumstances (such as that the couple cannot conceive). The deliberate and knowing choice of any intrinsically evil act is always objectively immoral, regardless of intention and circumstances.
Sex in Marriage
But another type of grave sin is also necessarily condemned by this teaching of Humanae Vitae, which is also taught by Pope Francis in Amoris Laetitia: unnatural sexual acts in marriage. An unnatural sexual act is any genital act that is not, by the very nature of the act, ordered toward the procreative meaning. Such acts includes oral, manual, or anal sexual acts, regardless of whether these acts include climax. Such acts are not inherently procreative, and therefore represent a “genital act of husband and wife” which refuses the procreative meaning of conjugal union.
Unnatural sexual acts have been condemned by Saints Augustine, Aquinas, and Liguori. They have never been approved by the Church, under any circumstances, for use as “foreplay” in marriage, nor for any other purpose between spouses. These sins are termed “acts of grave depravity” by the Catechism.
Catechism of the Catholic Church: Basing itself on Sacred Scripture, which presents homosexual acts as acts of grave depravity, tradition has always declared that “homosexual acts are intrinsically disordered.” They are contrary to the natural law. They close the sexual act to the gift of life. [CCC 2357]
Some Catholics opine that this condemnation of unnatural sexual acts only applies to persons of the same gender. But the reason for the condemnation of unnatural sexual acts is not solely that the persons are not male and female, or are not married. The Church also condemns unnatural sexual acts because they “close the sexual act to the gift of life”. For sexuality is ordered toward procreation. And this is the very reason that Humanae Vitae and Amoris Laetitia require every sexual act of the spouses to be open to life.
Saints Augustine and Aquinas clearly and strongly condemned unnatural sexual acts in marriage. See my article: May the Marriage Bed Be Immaculate. Saint Alphonsus Liguori, Doctor of the Church and a moral theologian, was particularly clear and specific in his condemnation of unnatural sexual acts in marriage: Saint Alphonsus Liguori on Marital Chastity. The claim that unnatural sexual acts are moral if the husband subsequently “completes the act” in the natural manner is specifically rejected by Saint Liguori, as is the claim that the spouses may use unnatural sexual acts on the wife after natural marital relations in order to for her to reach climax.
The wording used by Pope Francis is particularly clear: “no genital act of husband and wife can refuse this meaning”, i.e. the procreative meaning. Thus, Catholics cannot claim that husband and wife may use various types of unnatural genital acts, for any reason or purpose, in any circumstances. For such acts are unnatural precisely because they are not inherently procreative.
The only moral sexual act is natural marital relations open to life.
