_Direct._ XVI. Make careful choice of the books which you read. Let the holy Scriptures ever have the pre-eminence; and next them, the solid, lively, heavenly treatises, which best expound and apply the Scriptures; and next those, the credible histories, especially of the church, and tractates upon inferior sciences and arts: but take heed of the poison of the writings of false teachers, which would corrupt your understandings; and of vain romances, play-books, and false stories, which may bewitch your fantasies, and corrupt your hearts.
As there is a more excellent appearance of the Spirit of God in the holy Scriptures, than in any other book whatever, so it hath more power and fitness to convey the Spirit, and make us spiritual, by imprinting itself upon our hearts. As there is more of God in it, so it will acquaint us more with God, and bring us nearer him, and make the reader more reverent, serious, and divine. Let Scripture be first and most in your hearts and hands, and other books be used as subservient to it. The endeavours of the devil and papists to keep it from you, doth show that it is most necessary and desirable to you. And when they tell you, that all heretics plead the Scriptures, they do but tell you, that it is the common rule or law of christians, which therefore all are fain to pretend; as all lawyers and wranglers plead the law of the land, be their cause never so bad, and yet the laws must not be therefore concealed or cast aside: and they do but tell you, that in their concealment or dishonouring the Scriptures, they are worse than any of those heretics. When they tell you that the Scriptures are misunderstood, and abused, and perverted to maintain men's errors, they might also desire that the sun might be obscured, because the purblind do mistake, and murderers and robbers do wickedly by its light; and that the earth might be subverted, because it bears all evil-doers; and highways stopped up, because men travel in them to do evil; and food prohibited, because it nourisheth men's diseases. And when they have told you truly of a law or rule (whether made by pope or council) which bad men cannot misunderstand, or break, or abuse and misapply, then hearken to them, and prefer that law, as that which preventeth the need of any judgment.
The writings of divines are nothing else but a preaching the gospel to the eye, as the voice preacheth it to the ear. Vocal preaching hath the pre-eminence in moving the affections, and being diversified according to the state of the congregations which attend it: this way the milk cometh warmest from the breast. But books have the advantage in many other respects: you may read an able preacher, when you have but a mean one to hear. Every congregation cannot hear the most judicious or powerful preachers; but every single person may read the books of the most powerful and judicious. Preachers may be silenced or banished, when books may be at hand: books may be kept at a smaller charge than preachers: we may choose books which treat of that very subject which we desire to hear of; but we cannot choose what subject the preacher shall treat of. Books we may have at hand every day and hour; when we can have sermons but seldom, and at set times. If sermons be forgotten, they are gone. But a book we may read over and over till we remember it; and if we forget it, may again peruse it at our pleasure, or at our leisure. So that good books are a very great mercy to the world. The Holy Ghost chose the way of writing, to preserve his doctrine and laws to the church, as knowing how easy and sure a way it is of keeping it safe to all generations, in comparison of mere verbal tradition, which might have made as many controversies about the very terms, as there be memories or persons to be the preservers and reporters.
Books are (if well chosen) domestic, present, constant, judicious, pertinent, yea, and powerful sermons; and always of very great use to your salvation; but especially when vocal preaching faileth, and preachers are ignorant, ungodly, or dull, or when they are persecuted, and forbid to preach.
