Moral Theology: McHugh and Callan
https://www.gutenberg.org/cache/epub/35354/pg35354-images.htmlMorality of Kissing and Similar Acts.—(a) _Per se_, or from their nature, these acts are indifferent, since they can be employed, not only for evil (Job, xxxi. 27; Luke, xxii. 48), but also for good, as we see from the examples of the kiss of peace (I Thess., v. 26), the kiss of fraternal greeting (Gen., xxvii. 26, 27), and the kiss of respectful homage (Luke, vii. 38, 45).
(b) _Per accidens_, or from their circuмstances, these acts are often venially or mortally sinful against purity or against some other virtue, or against both. Thus, justice is offended by injuries or violence (e.g., stolen kisses, unhygienic kisses that transmit venereal or other disease); charity is offended by scandal given the object of affection or the onlookers (e.g., kisses given by way of greeting to a member of the opposite sex by an ecclesiastic or religious, kisses forced upon children by grown-ups and which are harmful to the youthful sense of modest reserve); purity itself is offended by familiarities which, though not impure in themselves, constitute a peril for the virtue of one or both parties, as is true especially in demonstrations of sensual affection or pleasure. But even though there be some carnal commotion, it is not unlawful to give with a pure intention the decent salutation customary in one’s country (e.g., to shake hands with a lady, to kiss one’s stepmother or sister-in-law).

Questions of Catholics Answered
PERTAINING TO COURTSHIP
By
The Rev. Winfrid Herbst S. D. S.
When a young man is keeping company with a girl with the intention of marriage, does he do wrong in
kissing her? Is it a mortal sin to kiss in a passionate way when keeping company? When is a kiss a sin
and when is it not? Will you kindly give your views, from all angles, on this subject of kissing in company
keeping?
When a person asks whether lovers are allowed to kiss one another, that asking at least indicates a certain
delicacy of conscience. You seem to want to do the right thing; and for this you are to be commended. We will
answer your question briefly, yet clearly.
Lovers who are engaged to be married may exchange respectable marks of affection and love, in a moderate
degree. A modest kiss is one such mark of affection. But it must remain modest, and must not become
willfully passionate and sensual, and, hence, grievously sinful. It will easily become thus sinful, if repeated
often at the same meeting. One friendly and pure goodnight kiss is not dangerous for engaged couples. But it
ought to be sufficient. The passionate and lingering kiss, or the so-called soul kiss between lovers, is a mortal
sin, because it offers the occasion and inducement to grievous sensual emotions and gratifications.
Relative to the question as to when kissing is sinful and when it is not, it may in general be said that whatever
conduct exposes you or your partner to the proximate danger of yielding to impurity in thought, desire, feeling,
or action, is a mortal sin. And if you say that passionate kisses do not involve this danger for you or your companion you are grossly deceiving yourself.
Such an assertion makes one think of a dulled conscience and a blinded soul.
Incipient or advanced lovers who are not yet engaged to be married should not at all indulge in kissing and
similar demonstrations of intimate and ardent love, since their relations are not close enough to warrant it. If
they embark at so early a stage upon these amorous practices, there is every danger that they will proceed from
what appears innocent and modest to what they know is not, and the magnitude of the harm and disaster that
will ensue to both parties will probably outrun all their calculations.
We believe that the above treats of our subject from all necessary angles and gives principles that will enable
you to act rightly in all circuмstances that may arise. We add, however, as a serious warning, that, though there
may be some who have no evil thoughts or desires whatsoever in kissing, and petting, they may be the occasion
of gross ins of immortal thoughts, desires, and emotions to their partners. Remember this safe and simple rule:
“Never do anything, when the two of you are alone, which you would be ashamed to do in the presence of your
parents; or which you would be ashamed to reveal to your parents.”
Short summary:
Only those engaged to marry should engage in a brief kiss goodbye. At all other times no, so as not to induce yourself or the other to sin (and for other reasons, such as not gaining a reputation as an "easy" girl).
