chap. 17. Some commands are given to all in common, others to particular classes Again, it often happens that a man who has attained, or thinks he has attained, to a higher grade of spiritual life, thinks that the commands given to those who are still in the lower grades are figurative; for example, if he has embraced a life of celibacy and made himself a eunuch for the kingdom of heaven's sake, he contends that the commands given in Scripture about loving and ruling a wife are not to be taken literally, but figuratively; and if he has determined to keep his virgin unmarried, he tries to put a figurative interpretation on the passage where it is said, "Marry thy daughter, and so shalt thou have performed a weighty matter." Accordingly, another of our rules for understanding the Scriptures will be as follows, to recognize that some commands are given to all in common, others to particular classes of persons, that the medicine may act not only upon the state of health as a whole, but also upon the special weakness of each member. For that which cannot be raised to a higher state must be cared for in its own state.
