2176. Definition of Adoration.—Adoration or worship is honor shown to God through bodily acts offered in acknowledgment of His supreme excellence and of our dependence on Him.
(a) Thus, it is acknowledgment of dependence on God, and as such it differs from mere honor, which may be shown even to an equal.
(b) It is an acknowledgment of supreme excellence, and so it differs from veneration shown to creatures who are above us. Adoration (_latria_), therefore, is not the same thing as the sacred cult or veneration shown the Blessed Virgin (_hyperdulia_) and the Saints (_dulia_) on account of their supernatural grace and glory; much less is it the same thing as the civil cult shown to persons illustrious for natural qualities, such as acquired knowledge, political dignity or power, etc.: “The Lord thy God shalt thou adore and Him only shalt thou serve” (Matt, iv. 10).
2177. Unity and Variety of Adoration.—Adoration is but one, though it has various expressions. (a) The unity of adoration depends on the unity of its object. There is but one God to whom belong the various divine attributes, and the three Divine Persons share the same majesty. Hence, there is but one adoration. (b) The variety in adoration is in the expression. The higher expression of adoration is internal: it does not depend on bodily acts or places, and it is offered by Angels as well as by man. The lower expression of adoration is made through bodily acts, such as genuflections, prostrations, prayer with face to the east, and the use of sacred places for worship, all of which externals are employed as aids to devotion and symbols of the divine glory (Matt., xviii, 20; Luke, xix. 46). Some of the actions here mentioned are sometimes used in the religious or civil cult shown to creatures, but internal adoration belongs to God alone.
2178. Definition of Sacrifice.—Sacrifice is the offering to God and a real changing of a sensible thing, made by a lawful minister, in acknowledgment of God’s supreme dominion and of our subjection to Him.
(a) It is an offering or oblation; that is, one makes a gift directly to God Himself. Thus, sacrifice differs from contributions of the people made for the clergy or the church.
(b) It offers a sensible thing, that is, some object perceptible by the senses or hidden under sensible species; for sacrifice is an outward sign of the inner offering, by which the soul itself is subjected to God.
(c) It is made by a lawful minister, for sacrifice is a public act performed in the name of the community, and hence it may be offered only by those who represent the community. St. Paul declares that a high-priest is chosen from men to offer sacrifice, and that no one may take the honor to himself unless he is called as Aaron was (Heb., v. 4).
(d) It is made to God alone, since God alone is our First Beginning and Last End: “He who sacrifices to other gods besides the Lord shall be put to death” (Exod., xxii. 20). Mass in honor of the Blessed Virgin or the Saints means that sacrifice is offered God in thanksgiving for their merits or in petition that we may imitate their virtues. Oblations may be made to men, but sacrifice may be offered only to God.
(e) It is through a real change of the thing offered, which thus becomes the victim of sacrifice; for the supreme act of worship reserved to God acts upon the substance itself of an external thing to signify that the worshipper offers his own being to God. The change in the thing sacrificed consists in its being made sacred, or set apart as the central object in the supreme act of worship.
