For many centuries no man was considered to be ingenious, who had not the skill and daring necessary for changing into a variety of curious shapes the sacred word of God. This was undoubtedly a contrivance of Satan to undermine the authority of Scripture, and to take away from the reading of it the true advantage. God visited this profanation by a just judgment, when he suffered the pure meaning of the Scripture to be buried under false interpretations.
Scripture, they say, is fertile, and thus produces a variety of meanings. I acknowledge that Scripture is a most rich and inexhaustible fountain of all wisdom; but I deny that its fertility consists in the various meanings which any man, at his pleasure, may assign. Let us know, then, that the true meaning of Scripture is the natural and obvious meaning; and let us embrace and abide by it resolutely. Let us not only neglect as doubtful, but boldly set aside as deadly corruptions, those pretended expositions, which lead us away from the natural meaning.
