“At the present time there are those who, basing themselves on observations in the psychological order, have begun to judge indulgently, and even to excuse completely, homosexual relations between certain people. This they do in opposition to the constant teaching of the Magisterium and to the moral sense of the Christian people.
A distinction is drawn, and it seems with some reason, between homosexuals whose tendency comes from a false education, from a lack of normal sexual development, from habit, from bad example, or from other similar causes, and is transitory or at least not incurable; and homosexuals who are definitively such because of some kind of innate instinct or a pathological constitution judged to be incurable.
In regard to this second category of subjects, some people conclude that their tendency is so natural that it justifies in their case homosexual relations within a sincere communion of life and love analogous to marriage, in so far as such homosexuals feel incapable of enduring a solitary life.
In the pastoral field, these homosexuals must certainly be treated with understanding and sustained in the hope of overcoming their personal difficulties and their inability to fit into society. Their culpability will be judged with prudence. But no pastoral method can be employed which would give moral justification to these acts on the grounds that they would be consonant with the condition of such people. For according to the objective moral order, homosexual relations are acts which lack an essential and indispensable finality. In Sacred Scripture they are condemned as a serious depravity and even presented as the sad consequence of rejecting God. This judgment of Scripture does not of course permit us to conclude that all those who suffer from this anomaly are personally responsible for it, but it does attest to the fact that homosexual acts are intrinsically disordered and can in no case be approved of.”
Author’s note: The above excerpt was taken from “Persona Humana: Declaration on Certain Questions Concerning Sexual Ethics,” Sacred Congregation for the Doctrine of the Faith, December 29, 1975. Of this section, the sentence that strikes me as the most profound is this one: “For according to the objective moral order, homosexual relations are acts which lack an essential and indispensable finality.” I imagine that which the Church is referring to is the realized “finality” in married heterosexual couplings brought about through conception, the bringing forth of life, and thus the ultimate joining of love between the husband and wife. This is even the case among those who are older or sterile; hence, the Biblical Abraham and Sarah and Zechariah and Elizabeth. In homosexual pairings the possibility of life arising is completely unfeasible, even under miraculous conditions; for, in the greatest wonder of them all, the virgin-birth of Jesus Christ, there was still the complimentary between God the Father and the Blessed Mother.
In homosexuality, ultimately, the finality is death. In modern times, this saw its definitive fruition with the rise of AIDS. Because, gay male sex becomes the instrument - not of completion and love, but of desperation, fear, and final annihilation. Lastly, it becomes suicidal as you give yourself over to an act which could altogether leave you lifeless: in very real terms, the transference of semen being deposited in the rectum instead of the vagina creates a sort of toxic dead zone within the body; see the article “Sexual behaviour and increased anal cancer;” http://www.nature.com/icb/journal/v75/n2/abs/icb199725a.html. And, beyond the physiological, gay sex also abandons everyone to unfulfillment since the act becomes the focus; the beginning, the middle and the end; once it’s done; the need to start over begins to swell inside. As the Church states, gay sex brings about no resolution; nothing is created; bonding – perhaps, a sense of comradery, something resembling love; but it’s forced and contrived – it essentially lacks the naturalness and ease of heterosexuality. After gay sex there is pain, swelling, and blood; it’s a tragic return to infantilism; the incapacity to heal; a constant repetition of childhood trauma. The only way out is to stop; then, in Christ, there is Hope and the promise of final happiness with Him.
