“Remember that every science is based upon an abstraction. An abstraction is taking a point of view or looking at things under a certain aspect or from a particular angle. All sciences are differentiated by their abstraction.”

“A teacher who cannot explain any abstract subject to a child does not himself thoroughly understand his subject; if he does not attempt to break down his knowledge to fit the child's mind, he does not understand teaching.”

“Science is not wisdom.”

“The science of a religious man must be scientific; the religion of a scientific man must be religious.”

“The sun which warms the plant can under other conditions also wither it. The rain which nourishes the flower can under other conditions rot it. The same sun shines upon mud that shines upon wax. It hardens the mud but softens the wax. The difference is not in the sun, but in that upon which it shines. The Divine Life which shines upon a soul that loves Him, softens it into everlasting life; that same Divine Life which shines upon the slothful soul, neglectful of God, hardens it into everlasting death.”

“Divinely wise souls often infuriate the worldly-wise because they always see things from the Divine point of view. The worldly are willing to let anyone believe in God if he pleases, but only on condition that a belief in God will mean no more than belief in anything else. They will allow God, provided that God does not matter. But taking God seriously is precisely what makes the saint. As St. Teresa put it, “What is not God to me is nothing.” This passion is called snobbish, intolerant, stupid, and unwarranted intrusion; yet those who resent it deeply wish in their own hearts that they had the saint’s inner peace and happiness.”

“The Book of Numbers relates that when the people murmured rebelliously against God, they were punished with a plague of fiery serpents, so that many lost their lives. When they repented, Moses was told by God to make a brazen serpent and set it up for a sign, and all those bitten by the serpents who looked upon that sign would be healed. Our Blessed Lord was now declaring that He was to be lifted up, as the serpent had been lifted up. As the brass serpent had the appearance of a serpent and yet lacked its venom, so too, when He would be lifted up upon the bars of the Cross, He would have the appearance of a sinner and yet be without sin. As all who looked upon the brass serpent had been healed of the bite of the serpent, so all who looked upon Him with love and faith would be healed of the bite of the serpent of evil.”
