74 For the love of Our Savior .Jesus Christ, therefore, we implore pastors of souls, by every means in their power, by instructions and catechisms, by word of mouth and written articles widely distributed, to warn Christian parents of their grave obligations. And this should be done not in a merely theoretical and general way, but with practical and specific application to the various responsibilities of parents touching the religious, moral and civil training of their children, and with indication of the methods best adapted to make their training effective, supposing always the influence of their own exemplary lives. The Apostle of the Gentiles did not hesitate to descend to such details of practical instruction in his epistles, especially in the Epistle to the Ephesians, where among other things he gives this advice: "And you, fathers, provoke not your children to anger." This fault is the result not so much of excessive severity, as of impatience and of ignorance of means best calculated to effect a desired correction; it is also due to the all too common relaxation of parental discipline which fails to check the growth of evil passions in the hearts of the younger generation. Parents therefore, and all who take their place in the work of education, should be careful to make right use of the authority given them by God, whose vicars in a true sense they are. This authority is not given for their own advantage, but for the proper up-bringing of their children in a holy and filial "fear of God, the beginning of wisdom," on which foundation alone all respect for authority can rest securely; and without which, order, tranquillity and prosperity, whether in the family or in society, will be impossible.
