(2.) If we compare the scriptures with other writings among Christians, which pretend not to inspiration, we shall find in these writings a great number of impure and false doctrines, derogatory to the glory of God, in many of the pretended expositions of Scripture. If therefore men, who have the Scripture in their hands, propagate unholy doctrines, they would do so much more were there no Scripture to guide them: thus the doctrine that grace is not necessary to what is spiritually good: the merit of good works, human satisfactions, penances, indulgences, and dispensations for sin, are all impure doctrines, which are directly contrary to Scripture; and, as contraries illustrate each other, so hereby the holiness and purity of Scripture, which maintains the contrary doctrines, will appear to those who impartially study it and understand the sense thereof. (3.) If we compare the Scriptures with the imposture of Mahomet, in the book called the Alcoran, which the Turks make use of as a rule of faith, and prefer it to Scripture, and reckon it truly divine, that contains a system not only of fabulous, but corrupt and impure notions, accommodated to men’s sensual inclinations. Thus it allows of polygamy, and many impurities in this world, and promises to its votaries a sensual paradise in the next, all which is contrary to Scripture; so that composures merely human, whether they pretend to divine inspiration or not, discover themselves not to be the word of God, by their unholiness; as the Scripture manifests itself to be divine, by the purity of its doctrine; and indeed, it cannot be otherwise, considering the corruption of man’s nature, as well as the darkness and blindness of his mind, which, if it pretends to frame a rule of faith, it will be like himself, impure and unholy; but that which has such marks of holiness, as the Scripture has, appears to be inspired by a holy God. Having considered the holiness of Scripture doctrines, we proceed to shew the weight of this argument, or how far it may be insisted on to prove its divine authority. It is to be confessed, that a book’s containing holy things or rules for a holy life, doth not of itself prove its divine original; for then other books might be called the word of God besides the Scripture, which is so called, not only as containing some rules that promote holiness, but as being the fountain of all true religion; and its being adapted above any book of human composure, to answer this end, affords an argument of some weight to prove it to be of God. For, 1. Man, who is prone to sin, naturally blinded and prejudiced against divine truth and holiness, could never compose a book that is so consonant to the divine perfections, and contains such a display of God’s glory, and is so adapted to make us holy.
