_Quest._ XIII. But what if one do purposely commit adultery, to be separated from the other? _Answ._ It is in the other's power and choice, whether to be divorced and depart, or not, as they find the good or evil consequents preponderate. _Quest._ XIV. Doth not infidelity dissolve the relation or obligation; seeing there is no communion between light and darkness, a believer and an infidel? _Answ._ It maketh it unlawful for a believer to marry an infidel (except in case of true necessity); because they can have no communion in religion. But it nullifieth not a marriage already made, nor maketh it lawful to depart or divorce; because they may have mere conjugal communion still. As the apostle purposely determineth the case, in 1 Cor. vii. _Quest._ XV. Doth not the desertion of one party disoblige the other? _Answ._ 1. It must be considered what is true desertion. 2. Whether it be a desertion of the relation itself for continuance, or only a temporary desertion of cohabitation, or congress. 3. What the temper and state of the deserted party is. 1. It is sometimes easy, and sometimes hard to discern which is the deserting party. If the wife go away from the husband unwarrantably, though she require him to follow her, and say that she doth not desert him, yet it may be taken for a desertion, because it is the man who is to rule and choose the habitation. But if the man go away, and the woman refuse to follow him, it is not he that is therefore the deserter. _Quest._ But what if the man have not sufficient cause to go away, and the woman hath great and urgent reasons not to go? As suppose that the man will go away in hatred of an able preacher, and good company, and the woman if she follow him, must leave all those helps, and go among ignorant, profane, heretical persons, or infidels; which is the deserter then?
