The Church teaches
that "those who in exercising it [the conjugal act] deliberately frustrate its
natural power and purpose sin against nature and commit a deed which is shameful
and intrinsically vicious." This remains so, regardless of age. [Please Note:
The items herein assumes one is talking about relations between persons who are
validly married. If not, such intimate relations themselves would be gravely

"But no reason,
however grave, may be put forward by which anything intrinsically against nature
may become conformable to nature and morally good. Since, therefore, the
conjugal act is destined primarily by nature for the begetting of children,
those who in exercising it deliberately frustrate its natural power and purpose
sin against nature and commit a deed which is shameful and intrinsically
vicious. Small wonder, therefore, if Holy Writ bears witness that the Divine
Majesty regards with greatest detestation this horrible crime and at times has
punished it with death. As St. Augustine notes, 'Intercourse even with one's
legitimate wife is unlawful and wicked where the conception of the offspring is
prevented. Onan, the son of Juda, did this and the Lord killed him for it (cf.
Gen. 38:9-10).'" (Pope Pius XI, "Casti Connubii", 1930 A.D.)
"[W]e must once
again declare that the direct interruption of the generative process already
begun, and, above all, directly willed and procured abortion, even if for
therapeutic reasons, are to be absolutely excluded as licit means of regulating
birth. Equally to be excluded, as the teaching authority of the Church has
frequently declared, is direct sterilization, whether perpetual or temporary,
whether of the man or of the woman. Similarly excluded is every action which,
either in anticipation of the conjugal act, or in its accomplishment, or in the
development of its natural consequences, proposes, whether as an end or as a
means, to render procreation impossible. To justify conjugal acts made
intentionally infecund, one cannot invoke as valid reasons the lesser evil, or
the fact that such acts would constitute a whole together with the fecund acts
already performed or to follow later, and hence would share in one and the same
moral goodness. In truth, if it is sometimes licit to tolerate a lesser evil in
order to avoid a greater evil or to promote a greater good, it is not licit,
even for the gravest reasons, to do evil so that good may follow therefrom; that
is, to make into the object of a positive act of the will something which is
intrinsically disordered, and hence unworthy of the human person, even when the
intention is to safeguard or promote individual, family or social well-being.
Consequently it is an error to think that a conjugal act which is deliberately
made infecund and so is intrinsically dishonest could be made honest and right
by the ensemble of a fecund conjugal life." (Pope Paul VI, 1968 A.D.)
"For since the
bringing of children into the world is the principal end of marriage, to do
anything in order to prevent the accomplishment of this end is always a mortal
sin." (St. Francis de Sales, Doctor of the Church)
"[A]s often as he
knows his wife without a desire for children...without a doubt he commits sin"
(St. Caesar of Arles, c. 540 A.D.)
whatsoever of matrimony exercised in such a way that the act is deliberately
frustrated in its natural power to generate life is an offense against the law
of God and of nature, and those who indulge in such are branded with the guilt
of a grave sin." (Pope Pius XI, "Casti Connubii", 1930 A.D.)
commerce, which is so holy, just and commendable in itself, and so profitable to
the commonwealth, is, nevertheless, in certain cases dangerous to those that
exercise it, as when the order appointed for the procreation of children is
violated and perverted; in which case, according as one departs more or less
from it, the sins are more or less abominable, but always mortal." (St. Francis
de Sales, Doctor of the Church)
On a merely human
level, please note that "Having intimate relations while using a condoms is
touted (by some) as safe sex", but in reality, condoms are reported to have "a
failure rate as high as 30%" and they "may not protect from venereal diseases or
AIDS." Even if they could protect the body, their use 'gravely harms the soul'.
And shouldn't one's eternal soul be far more important than one's body?
