2274. Superstition.—Superstition is false religion, or a vice that offers improper worship to the true God or divine worship to a false god. Improper worship of the true God is either false or superfluous.
(a) False worship is opposed to the truth of religion (e.g., Old Testament rites which signify that Christ is still to come), or of rites (e.g., Mass by a layman, Mass according to a form disapproved by the Church), or of facts (e.g., fictitious revelations, ecstasies, mysticism, miracles, relies), or of morals (e.g., human sacrifice, praises of God to the accompaniment of lascivious words or music, etc.).
(b) Superfluous worship is offered when an external observance in no way serves the purposes of religion (viz., the glory of God, the elevation of the soul to Him, the repression of the passions), or is opposed to law or common custom. The purposes of religion are not served by actions foolish in themselves (e.g., the repeated mumbling of meaningless sounds) or in their intent (e.g., undue emphasis given to minor details of a religious act, such as color of the candles on the altar, the stature of the celebrant, the hour or condition of the weather, etc., as if weighty consequences depended on them). The chain prayer is another example of a superstition that places all the virtue of an act of worship in some small external circumstance. The law and custom are not followed in such superstitions as additional crosses, alleluias, credos, etc., made in violation of Mass rubrics, or a devotion consisting of fasts on Sundays, or new forms of piety that lack ecclesiastical approval. There is no superstition, however, in modes of worship approved by the Church (such as novenas, tridua, Gregorian Masses, and the like), for the Church recognizes no devotion or ceremony unless it is true and useful as an expression of religion.
2275. The Sinfulness of Improper Worship of God.—(a) False worship is from its nature a grave sin; it is seriously insulting to God because it offers Him dishonor as honor, and it is also seriously harmful to man because it casts discredit by its falsity on the name of religion. (b) Superfluous worship is from its nature a venial sin, since it contains no notable irreverence towards God and, being outlawed, does not reflect on religion. Accidentally, however, it may be a mortal sin, as when it is performed in such a way as to cause great scandal.
2276. Worship of False Deity.—Worship of a false deity is performed by offering a creature an act of homage due to God alone. Hence, there are three species of this superstition: (a) a creature is recognized as God, when it is offered a service (such as sacrifice) that testifies to supreme and infinite excellence (idolatry); (b) a creature is given the credit of divine knowledge, when instruction about hidden matters which only God could bestow is asked from it (divination), (c) a creature is treated as the supreme ruler, when assistance which only God can grant is sought from it (vain observance).
2277. Definition of Idolatry.—Idolatry is the supreme worship of _latria_ offered to a creature.
(a) It is supreme worship, and hence the inferior reverence of _hyperdulia, dulia_, or civil honor, offered respectively to the Blessed Mother, angels, saints, superiors, etc., is not idolatry. The external signs of worship that belong to God alone (such as sacrifice, temples, priesthood, altars, etc.), may never be used in the veneration of creatures; nor the signs that are common to God and creatures (such as genuflexions, prostrations, prayers, etc.), if the intention is to adore.
(b) Idolatry is offered, that is, by it an act of worship is intended or is at least performed in a serious manner. Hence, it would not be idolatry so to enact a pagan ceremony that the onlookers could understand that no religious rite was being performed (e.g., if it were done on the stage, or in a joking manner).
(c) Idolatry is offered to a creature, and hence the relative honor that is shown the images of the Trinity or of Christ on account of the persons represented by them is not idolatry. The creature to whom idolatry is shown is either a person (e.g., an Angel, the soul of a departed person, a living human being), or an irrational creature (e.g., the bull Apis, a sacred plant), or an inanimate substance (e.g., statues or pictures, the elements, the heavenly bodies), or a fictitious being (e.g., Jupiter and the other gods of mythology).
2278. The Kinds of Idolatry.—(a) Idolatry is either internal or external. Internal idolatry has the intention to adore a creature, as when a Satanist offers sacrifice to demons. External idolatry performs an outward rite that signifies adoration of a creature, although there is no will to give adoration, as when a Christian out of fear of death reluctantly burns incense before an idol. (b) Internal idolatry is either perfect or imperfect. Perfect idolatry includes belief in a false god, as when an ignorant pagan prays to the sun and moon. Imperfect idolatry is committed when, without belief in a false god, there is the will to offer it divine worship on account of hatred of God, wish to obtain favors from demons, or the like.
