“Love consists of a commitment which limits one's freedom - it is a giving of the self, and to give oneself means just that: to limit one's freedom on behalf of another.”

“Limitation of one's freedom might seem to be something negative and unpleasant, but love makes it a positive, joyful and creative thing. Freedom exists for the sake of love.”

“True freedom is not advanced in the permissive society, which confuses freedom with license to do anything whatever and which in the name of freedom proclaims a kind of general amorality. It is a caricature of freedom to claim that people are free to organize their lives with no reference to moral values, and to say that society does not have to ensure the protection and advancement of ethical values. Such an attitude is destructive of freedom and peace.”

“Friendship, as has been said, consists in a full commitment of the will to another person with a view to that person's good.”

“What is the difference between “creator” and “craftsman”? The one who creates bestows being itself, he brings something out of nothing—ex nihilo sui et subiecti, as the Latin puts it—and this, in the strict sense, is a mode of operation which belongs to the Almighty alone. The craftsman, by contrast, uses something that already exists, to which he gives form and meaning.”

“Love between man and woman cannot be built without sacrifices and self-denial.”

“Take away from love the fullness of self surrender, the completeness of personal commitment, and what remains will be a total denial and negation of it.”
