There is, that is to say, the effect on the union itself.

For through harmonious sex relationships a deeper spiritual unity is reached than can possibly be derived from continence in or out of marriage, and the marriage association becomes an apter instrument in the service of the world.

Apart from any sexual craving, the complete spiritual contact of two persons who love each other can only be attained through some act of rare intimacy.

No act can be quite so intimate as the sexual embrace.

In its accomplishment, for all who have reached a reasonably human degree of development, the communion of bodies becomes the communion of souls.
