Pius XII on Pleasure

The same Creator, Who in His bounty and wisdom willed to make use of the work of man and woman, by uniting them in matrimony, for the preservation and propagation of the human race, has also decreed that in this function the parties should experience pleasure and happiness of body and spirit. Husband and wife, therefore, by seeking and enjoying this pleasure do no wrong whatever. They accept what the Creator has destined for them.
