Before I come to the proof, take these cautions: 1. Where I say men must thus teach, I imply they must be able to teach, and not teach before they are able; and if they be not able it is their own sin, God having vouchsafed them means for enablement. 2. Men must measure their teaching according to their abilities, and not pretend to more than they have, nor attempt that which they cannot perform, thereby incurring the guilt of proud self-conceitedness, profanation, or other abuse of holy things. For example, men that are not able judiciously to do it, must not presume to interpret the original, or to give the sense of dark prophecies, and other obscure texts of Scripture, nor to determine controversies beyond their reach. 3. Yet may such conveniently study what more learned, able men say to such cases; and tell their families, this is the judgment of fathers, or councils, or such and such learned divines. 4. But ordinarily it is the safest, humblest, wisest, and most orderly way for the master of the family to let controversies and obscure Scriptures alone, and to teach the plain, few necessary doctrines commonly contained in catechisms, and to direct in matters of necessary practice. 5. Family teaching must stand in a subordination to ministerial teaching, as families are subordinate to churches; and therefore, (1.) Family teaching must give place to ministerial teaching, and never be set against it; you must not be hearing the master of a family, when you should be in a church hearing the pastor; and if the pastor send for servants or children to be catechised in any fit place or at any fit time, the master is not then to be doing it himself, or to hinder them, but they must go first to the pastor to be taught; also if a pastor come into a family, the master is to give place, and the family to hear him first. (2.) And therefore when any hard text or controversies fall in, the master should consult with the pastor for their exposition, unless it fall out that the master of the family be better learned in the Scripture than the pastor is, which is rare, and rarer should be, seeing unworthy ministers should be removed, and private men that are worthy should be made ministers. And the pastors should be the ablest men in the congregation. Now to the proof (remembering still that whatsoever proves it the ruler's duty to teach, must needs prove it the family's duty to learn, and to hearken to his teaching that they may learn).
_Arg._ I. From Deut. xi. 18-21, "Therefore shall you lay up these my words in your hearts, and in your soul, and bind them for a sign upon your hand, that they may be as frontlets between your eyes; and you shall teach them your children, speaking of them when thou sittest in thy house, and when thou walkest by the way, and when thou liest down, and when thou risest up; and thou shalt write them upon the door-posts of thy house, and upon your gates; that your days may be multiplied, and the days of your children." The like words are in Deut. vi. 6-8, where it is said, "And thou shalt teach them diligently unto thy children." So Deut. iv. 9, "Teach them thy sons, and thy sons' sons."
Here there is one part of family duty, viz. teaching children the laws of God, as plainly commanded as words can express it.
_Arg._ II. From these texts which commend this. Gen. xviii. 18, 19, "All the nations of the earth shall be blessed in him, for I know him that he will command his children and his household after him; and they shall keep the way of the Lord;" and it was not only a command at his death what they should do when he was dead; for, 1. It cannot be imagined that so holy a man should neglect a duty all his lifetime, and perform it but at death, and be commended for that. 2. He might then have great cause to question the efficacy. 3. As God commandeth a diligent inculcating precepts on children, so no doubt it is a practice answerable to such precepts that is here commended; and it is not bare teaching, but commanding, that is here mentioned, to show that it must be an improvement of authority, as well as of knowledge and elocution.
So 2 Tim. iii. 15. From a child Timothy knew the Scripture by the teaching of his parents, as appeareth, 2 Tim. i. 5.
