Tarry not, I entreat, for another to teach thee; thou hast the oracles of God. No man teacheth thee as they; for he indeed oft grudgeth much for vainglory’s sake and envy. Hearken, I entreat you, all ye that are careful for this life, and procure books that will be medicines for the soul. If ye will not any other, yet get you at least the New Testament, the Apostolic Epistles, the Acts, the Gospels, for your constant teachers. If grief befall thee, dive into them as into a chest of medicines; take thence comfort of thy trouble, be it loss, or death, or bereavement of relations; or rather dive not into them merely, but take them wholly to thee; keep them in thy mind.
This is the cause of all evils, the not knowing the Scriptures. We go into battle without arms, and how ought we to come off safe? Well contented should we be if we can be safe with them, let alone without them. Throw not the whole upon us! Sheep ye are, still not without reason, but rational; Paul committeth much to you also. They that are under instruction, are not for ever learning; for then they are not taught. If thou art for ever learning, thou wilt never learn. Do not so come as meaning to be always learning; (for so thou wilt never know;) but so as to finish learning, and to teach others. In the arts do not all persons continue for set times, in the sciences, and in a word, in all the arts? Thus we all fix definitely a certain known time; but if ye are ever learning, it is a certain proof that ye have learned nothing.
