15. After such a fashion did Liberius of holy memory address you, in words beyond the reality of practice in most cases, but coming short of your performance, who have not only attained to the whole of discipline by your virtue, but have surpassed it in your zeal. For we are bidden to practise fasting, but only for single days; but you, multiplying nights and days, pass untold periods without food, and if ever requested to partake of some, and to lay aside your book a little while, you at once answer: “Man doth not live by bread alone, but by every word of God.” S. Matt. iv. 4. Your very meals consisted but of what food came to hand, so that fasting is to be preferred to eating what was repugnant; your drink is from the spring, your weeping and prayer combine, your sleep is on your book.
