Third Book. Cyprian to his son Quirinus, 4139 greeting. Of your faith and devotion which you manifest to the Lord God, beloved son, you asked me to gather out for your instruction from the Holy Scriptures some heads bearing upon the religious teaching of our school; 4140 seeking for a succinct course of sacred reading, so that your mind, surrendered to God, might not be wearied with long or numerous volumes of books, but, instructed with a summary of heavenly precepts, might have a wholesome and large compendium for nourishing its memory. And because I owe you a plentiful and loving obedience, I have done what you wished. I have laboured for once, that you might not always labour. 4141 Therefore, as much as my small ability could embrace, I have collected certain precepts of the Lord, and divine teachings, which may be easy and useful to the readers, in that a few things digested into a short space are both quickly read through, and are frequently repeated. I bid you, beloved son, ever heartily farewell. 4139     [Whom he had probably baptized. Elucidation XI.] 4140     [Whom he had probably baptized.
