As for the accursed superstition of wearing amulets (among which the earrings worn by men at the top of the ear on one side are to be reckoned), it is practised with the view not of pleasing men, but of doing homage to devils. But who can expect to find in Scripture express prohibition of every form of wicked superstition, seeing that the apostle says generally, "I would not that ye should have fellowship with devils," 1 and again, "What concord hath Christ with Belial?" 2 unless, perchance, the fact that he named Belial, while he forbade in general terms fellowship with devils, leaves it open for Christians to sacrifice to Neptune, because we nowhere read an express prohibition of the worship of Neptune! Meanwhile, let those unhappy people be admonished that, if they persist in disobedience to salutary precepts, they must at least forbear from defending their impieties, and thereby involving themselves in greater guilt. But why should we argue at all with them if they are afraid to take off their earrings, and are not afraid to receive the body of Christ while wearing the badge of the devil?
As to ordaining a man who was baptized in the Donatist sect, I cannot take the responsibility of recommending you to do this; it is one thing for you to do it if you are left without alternative, it is another thing for me to advise that you should do it.
