But when the student of the Holy Scriptures, prepared in the way I have indicated, shall enter upon his investigations, let him constantly meditate upon that saying of the apostle’s, ‘Knowledge puffeth up, but charity edifieth.’ For so he will feel that, whatever may be the riches he brings with him out of Egypt, yet unless he has kept the Passover, he cannot be safe. Now Christ is our Passover sacrificed for us, and there is nothing the sacrifice of Christ more clearly teaches us than the call which He himself addresses to those whom He sees toiling in Egypt under Pharaoh: ‘Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.’ To whom is it light but to the meek and lowly in heart, whom knowledge does not puff up, but charity edifieth?
–St. Augustine, On Christian Doctrine
