“211 In the second place, remember that it is not only an honorable estate but also a necessary one, and it is solemnly commanded by God that in general men and women in all conditions, who have been created for it, shall be found in this estate. Yet there are some (although few) exceptions whom God has especially exempted — some who are unsuited for married life and others whom he has released by a high supernatural gift so that they can maintain chastity outside of marriage. 212 Where nature has its way, as God implanted it, it is not possible to remain chaste outside of marriage; for flesh and blood remain flesh and blood, and the natural inclinations and stimulations have their way without let or hindrance, as everyone’s observation and experience testify. Therefore, to make it easier for man to avoid unchastity in some measure, God has established marriage, so that everyone may have his allotted portion and be satisfied with it — although here, too, God’s grace is still required to keep the heart pure.
