“Nature exists for man to exploit for his own ends, while the end of man himself is nothing else but to serve God, to be grateful to Him, and to worship Him alone.”

“By the grace of reality and the nature of life, man–every man–is an end in himself, he exists for his own sake, and the achievement of his own happiness is his highest moral purpose”

“Be Grateful to the Man you help, think of Him as God. Is it not a great privilege to be allowed to worship God by helping our fellow men?”

“What is "grace"? It is God's own life, shared by us. God's life is love. Deus caritas est. By grace we are able to share in the infinitely selfless love of Him Who is such pure actuality that He needs nothing and therefore cannot conceivably exploit anything for selfish ends. Indeed, outside of Him there is nothing, and whatever exists exists by His free gift of its being, so that one of the notions that is absolutely contradictory to the perfection of God is selfishness.”

“Man is a fallen star till he is right with heaven: he is out of order with himself and all around him till he occupies his true place in relation to God. When he serves God, he has reached that point where he doth serve himself best, and enjoys himself most. It is man's honour, it is man's joy, it is man's heaven, to live unto God.”

“Neither son loved the father for himself. They both were using the father for their own self-centered ends rather than loving, enjoying, and serving him for his own sake. This means that you can rebel against God and be alienated from him either by breaking his rules or by keeping all of them diligently. It's a shocking message: Careful obedience to God's law may serve as a strategy for rebelling against God.”
