"There is no such thing as giving the body without giving the soul. Those who think they can be faithful in soul to one another, but unfaithful in body, forget that the two are inseparable. Sex in isolation from personality does not exist! An arm living and gesticulating apart from the living organism is an impossibility. Man has no organic functions isolated from his soul. There is involvement of the whole personality. Nothing is more psychosomatic than the union of two in one flesh; nothing so much alters a mind, a will, for better or for worse. The separation of soul and body is death. Those who separate sex and spirit are rehearsing for death. The enjoyment of the other's personality through one's own personality, is love. The pleasure of animal function through another's animal function is sex separated from love."
— Fulton J. Sheen, Three to Get Married
