“God does not demand that every man attain to what is theoretically highest and best. It is better to be a good street sweeper than a bad writer, better to be a good bartender than a bad doctor, and the repentant thief who died with Jesus on Calvary was far more perfect than the holy ones who had Him nailed to the cross. And yet, abstractly speaking, what is more holy than the priesthood and less holy than the state of a criminal? The dying thief had, perhaps, disobeyed the will of God in many things: but in the most important event of his life he listened and obeyed. The Pharisees had kept the law to the letter and had spent their lives in the pursuit of a most scrupulous perfection. But they were so intent upon perfection as an abstraction that when God manifested His will and His perfection in a concrete and definite way they had no choice but to reject it.”

“The Holy Spirit is the most perfect gift of the Father to men, and yet He is the one gift which the Father gives most easily.”

“Only the man who has had to face despair is really convinced that he needs mercy. Those who do not want mercy never seek it. It is better to find God on the threshold of despair than to risk our lives in a complacency that has never felt the need of forgiveness. A life that is without problems may literally be more hopeless than one that always verges on despair.”

“Peace demands the most heroic labor and the most difficult sacrifice. It demands greater heroism than war. It demands greater fidelity to the truth and a much more perfect purity of conscience.”

“The whole function of the life of prayer is, then, to enlighten and strengthen our conscience so that it not only knows and perceives the outward, written precepts of the moral and divine laws, but above all lives God's law in concrete reality by perfect and continual union with His will.”

“The Holiness of God is something more and other than moral perfection: His claim upon us is something more and other than the claim of moral duty.”

“Contemplation means rest, suspension of activity, withdrawal into the mysterious interior solitude in which the soul is absorbed in the immense and fruitful silence of God and learns something of the secret of His perfections less by seeing than by fruitive love.”
