“[An]… important fact… well established is, that true religion prevails in any community, in proportion to the degree in which the young are instructed in the facts and indoctrinated in the truths of the Bible… The question does not concern the reason why the religious education of the young is so important; or the way in which that education can most advantageously be secured; but simply the fact that where the young are from the beginning imbued with the knowledge of the Bible, there pure Christianity abides; and where they are allowed to grow up in ignorance of divine truth, there true religion languishes and loses more and more its power. Such is the testimony of experience.
It is, therefore, the united testimony of Scripture and of history that the Bible, the Word of God, is the great means of promoting the sanctification and salvation of men, that is, of securing their temporal and eternal well being. Those consequently who are opposed to religion; who desire the reign of indifferentism, or the return of heathen doctrines and heathen morality, are consistent and wise in their generation, in endeavouring to undermine the authority of the Bible; to discourage its circulation; to discountenance attendance on its preaching; and especially to oppose its being effectually taught to the young. Those on the other hand who believe that without holiness no man can see God, and that without the light of divine truth, holiness is impossible, are bound as pastors, as parents, and as citizens to insist that the Bible shall have free course, and that it shall be faithfully taught to all under their influence or for whose training they are responsible.”
