FOURTH ARTICLE [II-II, Q. 154, Art. 4]

Whether There Can Be Mortal Sin in Touches and Kisses?

Objection 1: It would seem that there is no mortal sin in touches and

kisses. For the Apostle says (Eph. 5:3): "Fornication and all

uncleanness, or covetousness, let it not so much as be named among

you, as becometh saints," then he adds: "Or obscenity" (which a gloss

refers to "kissing and fondling"), "or foolish talking" (as "soft

speeches"), "or scurrility" (which "fools call geniality--i.e.

jocularity"), and afterwards he continues (Eph. 5:5): "For know ye

this and understand that no fornicator, or unclean, or covetous

person (which is the serving of idols), hath inheritance in the

kingdom of Christ and of God," thus making no further mention of

obscenity, as neither of foolish talking or scurrility. Therefore

these are not mortal sins.

Obj. 2: Further, fornication is stated to be a mortal sin as being

prejudicial to the good of the future child's begetting and

upbringing. But these are not affected by kisses and touches or

blandishments. Therefore there is no mortal sin in these.

Obj. 3: Further, things that are mortal sins in themselves can never

be good actions. Yet kisses, touches, and the like can be done

sometimes without sin. Therefore they are not mortal sins in

themselves.

_On the contrary,_ A lustful look is less than a touch, a caress or a

kiss. But according to Matt. 5:28, "Whosoever shall look on a woman

to lust after her hath already committed adultery with her in his

heart." Much more therefore are lustful kisses and other like things

mortal sins.

Further, Cyprian says (Ad Pompon, de Virgin., Ep. lxii), "By their

very intercourse, their blandishments, their converse, their

embraces, those who are associated in a sleep that knows neither

honor nor shame, acknowledge their disgrace and crime." Therefore by

doing these things a man is guilty of a crime, that is, of mortal sin.

_I answer that,_ A thing is said to be a mortal sin in two ways.

First, by reason of its species, and in this way a kiss, caress, or

touch does not, of its very nature, imply a mortal sin, for it is

possible to do such things without lustful pleasure, either as being

the custom of one's country, or on account of some obligation or

reasonable cause. Secondly, a thing is said to be a mortal sin by

reason of its cause: thus he who gives an alms, in order to lead

someone into heresy, sins mortally on account of his corrupt

intention. Now it has been stated above (I-II, Q. 74, A. 8), that it

is a mortal sin not only to consent to the act, but also to the

delectation of a mortal sin. Wherefore since fornication is a mortal

sin, and much more so the other kinds of lust, it follows that in

such like sins not only consent to the act but also consent to the

pleasure is a mortal sin. Consequently, when these kisses and

caresses are done for this delectation, it follows that they are

mortal sins, and only in this way are they said to be lustful.

Therefore in so far as they are lustful, they are mortal sins.

Reply Obj. 1: The Apostle makes no further mention of these three

because they are not sinful except as directed to those that he had

mentioned before.

Reply Obj. 2: Although kisses and touches do not by their very nature

hinder the good of the human offspring, they proceed from lust, which

is the source of this hindrance: and on this account they are

mortally sinful.

Reply Obj. 3: This argument proves that such things are not mortal

sins in their species.
