By this also you may perceive who they be that have no call to marry, and to whom it is a sin. As, 1. No man hath a call to marry, who laying all the commodities and discommodities together, may clearly discern that a married state is like to be a greater hinderance of his salvation, or to his serving or honouring God in the world, and so to disadvantage him as to his ultimate end. _Quest._ But what if parents do command it? or will set against me if I disobey? _Answ._ Parents have no authority to command you any thing against God or your salvation, or your ultimate end. Therefore here you owe them no formal obedience: but yet the will of parents, with all the consequents, must be put into the scales with all other considerations, and if they make the discommodities of a single life to become the greater, as to your end, then they may bring you under a duty or obligation to marry; not _necessitate præcepti_, as obedience to their command; but _necessitate medii_, as a means to your ultimate end, and in obedience to that general command of God, which requireth you to "seek first" your ultimate end, even "the kingdom of God, and his righteousness," Matt. vi. 33. _Quest._ But what if I have a corporal necessity, and yet I can foresee that marriage will greatly disadvantage me as to the service of God and my salvation? _Answ._ 1. You must understand that no corporal necessity is absolute: for there is no man so lustful but may possibly bridle his lust by other lawful means; by diet, labour, sober company, diverting business, solitude, watching the thoughts and senses, or at least by the physician's help; so that the necessity is but _secundum quid_, or an urgency rather than a simple necessity. And then, 2. This measure of necessity must be itself laid in the balance with the other accidents; and if this necessity will turn the scales by making a single life more disadvantageous to your ultimate end, your lust being a greater impediment to you than all the inconveniencies of marriage will be, then the case is resolved, "it is better to marry than to burn." But if the hinderances in a married state are like to be greater, than the hinderances of your concupiscence, then you must set yourself to the curbing and curing of that concupiscence; and in the use of God's means expect his blessing.
