A saying of Chrysostom’s has always pleased me very much, that the foundation of our philosophy is humility. But that of Augustine pleases me even more: ‘. . . so if you ask me concerning the precepts of the Christian religion, first, second and third, and always I would answer ‘Humility.’” John Calvin, Institutes, 2.2.11.
“Another observation, in a former letter of yours, has not escaped my remembrance – the three lessons which a minister has to learn: 1. Humility. 2. Humility. 3. Humility. How long are we learning the true nature of Christianity!” - Charles Simeon, quoted in Charles Simeon, by H. C. G. Moule (London, 1956), page 65.
“According to Christian teachers, the essential vice, the utmost evil, is Pride. Unchastity, anger, greed, drunkenness, and all that, are mere fleabites in comparison. It was through Pride that the devil became the devil. Pride leads to every other vice. It is the complete anti-God state of mind.” - C. S. Lewis, Mere Christianity (New York, 1958), page 94.
