Sexual Morality

Is Masturbation considered a mortal sin or not.

Since it is a grave matter, it may be a mortal sin. The Catholic teaching is in the Catechism of the Catholic Church: Offenses against chastity

2351 *Lust *is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes.

2352 By *masturbation *is to be understood the deliberate stimulation of the genital organs in order to derive sexual pleasure. "Both the Magisterium of the Church, in the course of a constant tradition, and the moral sense of the faithful have been in no doubt and have firmly maintained that masturbation is an intrinsically and gravely disordered action."138 “The deliberate use of the sexual faculty, for whatever reason, outside of marriage is essentially contrary to its purpose.” For here sexual pleasure is sought outside of "the sexual relationship which is demanded by the moral order and in which the total meaning of mutual self-giving and human procreation in the context of true love is achieved."139

To form an equitable judgment about the subjects’ moral responsibility and to guide pastoral action, one must take into account the affective immaturity, force of acquired habit, conditions of anxiety or other psychological or social factors that lessen, if not even reduce to a minimum, moral culpability.

Yes, it is objectively grave, which means that when full knowledge and full consent are present at the same time, it is a mortal sin. For the individual there may be mitigating circumstances (lack of full knowledge or full consent due to various factors).

It a grave sin, that is for certain. But I think we may need to look at it from another angle.

The RCC teach it is a sin. But masturbation in itself are not mentioned in The Bible. What make it a sin is the “lust factor”. To get sexually aroused do need some sort of lure, wich is, mainly porn. (And that is one that is wrong.) So if we look at it from this side, masturbation can, and now I am only speculating and twist words, so please don’t get offended, if we for arguments sake use our wife/husband as “lure” it is not a sin.

So, we can conlude that there is one kind of masturbation that is not a sin, it is however only a case of argumenting and advocate a issue that can not be proved because it is between God and some person. So to be on safe side, keep it, as The Church teach, as a grave sin. We must, haven said that, keep in mind that it is a sin we all have been guilty to, but it are also a sin that will be forgiven.

False. Masturbation is always a sin because it is objectively disordered and treats the human person as a mere means to the end of pleasure. Even if there were no lust going on, it would still be sinful in itself.


It is a species of lust, and also because solitary sexual stimulation is “contrary to the natural order of the venerial act as becoming to the human race” per St. Thomas. (Summa Theologica II, II, Q 157, A. 11) In the Old Testament is is referred to as uncleanness, and additionally in the New as effeminacy.

Leviticus 15:16-18, 1 Corinthians 6:9.
Numbered with lust 2 Corinthians 12:21.
And see: Galatians 5:19-21, Ephesians 5:5-8.

CCC 2351 Lust is disordered desire for or inordinate enjoyment of sexual pleasure. Sexual pleasure is morally disordered when sought for itself, isolated from its procreative and unitive purposes.

Yup. I agree. Above I was just pointing out that even if it could theoretically exist without “lust” as commonly understood, it would still be sinful because of the reasons you pointed out from St. Thomas, and because it runs counter to the dignity of the human person. Thanks for letting me clarify :slight_smile:

I was only speculating, never said it is not a sin. Foremost I wanted to give a perspective to a question. (Mea culpa?) I did not say it is OK. And I would like to remark that sex without lust is not possible.
