Apostolic Injunctions, Book VIII, Sec. IV:
"He that is guilty of sins not to be named, a sodomite, an effeminate person, a magician, an enchanter, an astrologer, a diviner, an user of magic verses, a juggler, a mountebank, one that makes amulets, a charmer, a soothsayer, a fortune-teller, an observer of palmistry; he that, when he meets you, observes defects in the eyes or feet of the birds or cats, or noises, or symbolical sounds: let these be proved for some time, for this sort of wickedness is hard to be washed away; and if they leave off those practices, let them be received;"
St. Ephraim the Syrian, Homily on Admonition and Repentance:
"Regard not spells and divinations, for that is communion with Satan."
St. Cyril of Jerusalem, Catechetical Lectures:
"Also give heed neither to observations of the stars nor auguries, nor omens, nor to the fabulous divinations of the Greeks. Witchcraft, and enchantment, and the wicked practices of necromancy, admit not even to a hearing."
"The watching of birds, divination, omens, or amulets, or charms written on leaves, sorceries, or other evil arts, and all such things, are services of the devil; therefore shun them."
St. Epiphanius of Cyprus, Panarion, Book III:
A Concise, Accurate Account of the Faith of the Catholic and Apostolic Church (De Fide)
24,3 The church refrains from fellowship with any sect. It forbids fornication, adultery, licentiousness, idolatry, murder, all law-breaking, magic, sorcery, astrology, palmistry, the observation of omens, charms, and amulets, the things called phylacteries. (4) It forbids theatrical shows, hunting, horse <races>, musicians and all evil-speaking and slander, all quarreling and blasphemy, injustice, covetousness and usury. (5) It does not accept actors, but regards them as the lowest of the low. It accepts offerings from people who are not wrong-doers and law-breakers, but live righteously.
