The husband of an incontinent wife: cuckolds, however, are Christians, as we learn by the following story: An old woman hearing a man call his dog Cuckold, reproved him sharply, saying, ‘Sirrah, are not you ashamed to call a dog by a Christian’s name?’ To cuckold the parson; to bed with one’s wife before she has been churched.
