Section I. Wrong Ways of Worshipping God

God may be wrongly worshipped either by false worship or by superfluous worship being paid him. Worship of God is false when its meaning is not in accordance with fact, or when the falsehood is in the person who performs the act of worship, as when a layman performs the duties of a priest, or when someone tries to gain credence for false miracles or false relics. The ceremonies and practices of the Jewish religion signified that the Messiah was to come, and so now, after the coming of our Lord, they could not be employed without superstition. Inasmuch as falsehood in religion is a grave injury to God, this species of superstition is mortally sinful.

Anything in the worship of God which does not tend to his honour and glory, or which is against the ordinances and practice of the Church, to whom the regulation of religious worship exclusively belongs, is superfluous worship and superstition. This sin is committed by attributing an infallible effect to a fixed number of prayers or acts of piety, or to the mere material wearing of scapulars or medals, or by unwarrantably acting against the rubrics while saying Mass or administering the sacraments or sacramentals of the Church. The intention of the Church is that scapulars, medals, and other pious objects should be used by the faithful with confidence in the goodness and power of God, whose aid is invoked on the wearers by the blessing of the Church. Ordinarily, however, this kind of superstition will not be more than a venial sin.
