822. Contrary unbelief (see 818), which not only refuses to believe but also assents to contrary errors, has three degrees according to the greater or less number of truths denied or errors admitted in these three degrees. Some theologians see different species of unbelief, while other theologians regard them as only accidental modes or circumstances of the one species of sin. (a) The most extensive denial of faith is found in infidelity, which rejects both Christ and His revelation. To this form of unbelief belong atheism, agnosticism, pantheism, paganism, polytheism, animism, and denials of Christ and Christianity. The chief religious bodies today that profess such errors are: Confucianism, Taoism and Shintoism (founded in China and Japan), which are polytheistic and practise idolatry and ancestor worship; Brahmanism (founded about 14 centuries before Christ), which is polytheistic or animistic: Buddhism (founded 6th century B.C. in India), which is polytheistic and practises idolatry; Zoroastrianism (founded in Persia about the 7th century B.C.), which is dualistic; Mohammedanism (founded in Arabia in the 6th century A.D.), which makes Mohammed and his religion superior to Christ and Christianity, and rejects the Trinity and the Incarnation. (b) A less complete departure from faith is found when Christ and His revelation are accepted as contained in the figures and prophecies of the Old Testament, but rejected in their fulfillment and development in Jesus and the New Testament. This is the error of Judaism, which today has about 15 million adherents. (c) A still smaller degree of rejection of faith exists when Christ is recognized as leader and teacher, but not all of His revelation is accepted. This kind of error is called heresy, and those bodies which profess it are known as sects. The chief heresies in times past were Gnosticism and Manicheism in the first centuries; Arianism and Macedonianism in the fourth century; Nestorianism, Monophysism and Pelagianism in the fifth century; Monothelism in the seventh century; Iconoclasm in the eighth century; Photianism in the ninth century; Albigensianism in the eleventh century; Waldensianism in the twelfth century; Wicliffism in the fourteenth century; Hussism in the fifteenth century; Protestantism in the sixteenth century, and Modernism in the twentieth century. Today, the erring Christian groups outside the Church are the Orientals, called Orthodox, and the Protestants. 823. Since error is not consistent, false teachings are found that accept all the above-mentioned degrees of unbelief, or borrow impartially from all.
