The world desire for their children that which is earthly and perishable, such as money, honour, fame and wealth. From infancy they train them up to vice, pride, haughtiness and idolatry. But with you, who are born of God, this is not the case; for it behooves you to seek something else for your children ; namely, that which is heavenly and eternal, and hence it is your duty to bring them up in the nurture and admonition of the Lord, as Paul teaches.
Moses commanded Israel to teach their children the law and commandments of the Lord, to talk of them when they sat down in their houses, and when they walked by the way, and when they lay down, and when they rose up. Now, since we are a chosen generation, a royal priesthood, a holy nation, a peculiar people, that we should show forth the praises of him who hath called us out of darkness into his marvellous light; therefore it behooves us to show ourselves patterns and examples in all righteousness and blamelessness. And to appear unto the whole world as we are thereunto called; for if we do not keep a strict eye upon our own children, but permit them to follow their evil inclination, corrupt nature and disposition, not correcting and chastising them according to the word of the Lord, we may with the greatest propriety lay our hands upon our mouths, and remain silent. For why should we teach those not of our household, when we take no pains to preserve our own families in the love and fear of God? Paul says, “If any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel”.
My beloved brethren and sisters in Christ, who sincerely love the word of the Lord, thus instruct your children from youth up, and daily admonish them with the word of the Lord, setting a good example. Teach and admonish them, I say, in proportion to the development of their understanding; constrain and correct them with discretion and moderation, without anger or bitterness lest they be discouraged; spare not the rod, if reason and necessity require it.
Beloved brethren in Christ, if you rightly know God and his word, and believe that the end of the righteous is everlasting life, and the end of the wicked eternal death, endeavour to the utmost of your power, to conduct your children in the way of life, and divert them from the way of death, as far as in you lies. Pray to Almighty God for the gift of his grace, that in his great mercy, he may guide and preserve them in the right path, through the directing influence of his Holy Spirit. Watch over their salvation as for your own souls. Teach, instruct, admonish, threaten, correct and chastise them, as circumstances require. Keep them away from naughty, wicked children, among whom they hear and learn nothing but lying, cursing, swearing, fighting and knavery. Have them instructed in reading and writing, bring them up to habits of industry, and let them learn such trades as are suitable, expedient and adapted to their age and constitution. If you do this, you shall live to see much honour and joy of your children. But if you do it not, heaviness of heart shall consume you at last. For a child left to himself, without reproof, is not only the shame of his father, but he bringeth his mother to shame.
-Menno Simons, 1557
