“Let this, therefore, in the first place, be laid down as an unassailable position, that the virtue which makes the life good has its throne in the soul, and thence rules the members of the body, which becomes holy in virtue of the holiness of the will; and that while the will remains firm and unshaken, nothing that another person does with the body, or upon the body, is any fault of the person who suffers it, so long as he cannot escape it without sin.

“But since purity is a virtue of the soul, and has for its companion virtue, the fortitude which will rather endure all ills than consent to evil; and since no one, however magnanimous and pure, has always the disposal of his own body, but can control only the consent and refusal of his will, what sane man can suppose that, if his body be seized and forcibly made use of to satisfy the lust of another, he thereby loses his purity? For if purity can be thus destroyed, then assuredly purity is no virtue of the soul; nor can it be numbered among those good things by which the life is made good, but among the good things of the body, in the same category as strength, beauty, sound and unbroken health, and, in short, all such good things as may be diminished without at all diminishing the goodness and rectitude of our life. But if purity be nothing better than these, why should the body be perilled that it may be preserved? If, on the other hand, it belongs to the soul, then not even when the body is violated is it lost. Nay more, the virtue of holy continence, when it resists the uncleanness of carnal lust, sanctifies even the body, and therefore when this continence remains unsubdued, even the sanctity of the body is preserved, because the will to use it holily remains, and, so far as lies in the body itself, the power also.

“For the sanctity of the body does not consist in the integrity of its members, nor in their exemption from all touch; for they are exposed to various accidents which do violence to and wound them.”  St. Augustine - City of God, excerpts from Book I, chapter 16 and 18.
