Catechism of the Council of Trent: On the Sacraments
Kind of Sacred Thing Meant Here
We have seen that there are many kinds of signs. The sacred thing referred to is also of more than one kind. As regards the definition already given of a Sacrament, theologians prove that by the words sacred thing is to be understood the grace of God, which sanctifies the soul and adorns it with the habit of all the divine virtues; and of this grace they rightly consider the words sacred thing, an appropriate appellation, because by its salutary influence the soul is consecrated and united to God.
In order, therefore, to explain more fully the nature of a Sacrament, it should be taught that it is a sensible object which possesses, by divine institution, the power not only of signifying, but also of accomplishing holiness and righteousness. Hence it follows, as everyone can easily see, that the images of the Saints, crosses and the like, although signs of sacred things, cannot be called Sacraments. That such is the nature of a Sacrament is easily proved by the example of all the Sacraments, if we apply to the others what has been already said of Baptism; namely, that the solemn ablution of the body not only signifies, but has power to effect a sacred thing which is wrought interiorly by the operation of the Holy Ghost.
Other Sacred Things Signified By The Sacraments
Now it is especially appropriate that these mystical signs, instituted by God, should signify by the appointment of the Lord not only one thing, but several things at once.
All The Sacraments Signify Something Present, Something Past, Something Future:
This applies to all the Sacraments; for all of them declare not only our sanctity and justification, but also two other things most intimately connected with sanctification, namely, the Passion of Christ our Redeemer, which is the source of our sanctification, and also eternal life and heavenly bliss, which are the end of sanctification. Such, then, being the nature of all the Sacraments, holy Doctors justly hold that each of them has a threefold significance: they remind us of something past; they indicate and point out something present; they foretell something future.
Nor should it be supposed that this teaching of the Doctors is unsupported by the testimony of Holy Scripture. When the Apostle says: All we who are baptised in Christ Jesus, are baptised in his death, he gives us clearly to understand that Baptism is called a sign, because it reminds us of the death and Passion of our Lord. When he says, We are buried together with him by baptism into death; that as Christ is risen from the dead by the glory of the Father, so, we also may walk in newness of life, he also clearly shows that Baptism is a sign which indicates the infusion of divine grace into our souls, which enables us to lead a new life and to perform all the duties of true piety with ease and cheerfulness. Finally, when he adds: If we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection, he teaches that Baptism clearly foreshadows eternal life also, which we are to reach through its efficacy.
A Sacrament Sometimes Signifies The Presence Of More Than One Thing
Besides the different significations already mentioned, a Sacrament also not infrequently indicates and marks the presence of more than one thing. This we readily perceive when we reflect that the Holy Eucharist at once signifies the presence of the real body and blood of Christ and the grace which it imparts to the worthy receiver of the sacred mysteries.
What has been said, therefore, cannot fail to supply the pastor with arguments to prove how much the power of God is displayed, how many hidden miracles are contained in the Sacraments of the New Law; that thus all may understand that they are to be venerated and received with utmost devotion.
Why the Sacraments were Instituted
Of all the means employed to teach the proper use of the Sacraments, there is none more effectual than a careful exposition of the reasons of their institution. Many such reasons are commonly assigned.
The first of these reasons is the feebleness of the human mind. We are so constituted by nature that no one can aspire to mental and intellectual knowledge unless through the medium of sensible objects. In order, therefore, that we might more easily understand what is accomplished by the hidden power of God, the same sovereign Creator of the universe has most wisely, and out of His tender kindness towards us, ordained that His power should be manifested to us through the intervention of certain sensible signs. As St. Chrysostom happily expresses it: If man were not clothed with a material body, these good things would have been presented to him naked and without any covering; but as the soul is joined to the body, it was absolutely necessary to employ sensible things in order to assist in making them understood.
Another reason is because the mind yields a reluctant assent to promises. Hence, from the beginning of the world, God was accustomed to indicate, and usually in words, that which He had resolved to do; but sometimes, when designing to execute something, the magnitude of which might weaken a belief in its accomplishment, He added to words other signs, which sometimes appeared miraculous. When, for instance, God sent Moses to deliver the people of Israel, and Moses, distrusting the help even of God who had commissioned him, feared that the burden imposed was heavier than he could bear, or that the people would not heed his message, the Lord confirmed His promise by a great variety of signs. As, then, in the Old Law, God ordained that every important promise should be confirmed by certain signs, so in the New Law, Christ our Saviour, when He promised pardon of sin, divine grace, the communication of the Holy Spirit, instituted certain visible and sensible signs by which He might oblige Himself, as it were, by pledges, and make it impossible to doubt that He would be true to His promises.
A third reason is that the Sacraments, to use the words of St. Ambrose, may be at hand, as the remedies and medicines of the Samaritan in the Gospel, to preserve or recover the health of the soul. For, through the Sacraments, as through a channel, must flow into the soul the efficacy of the Passion of Christ, that is, the grace which He merited for us on the altar of the cross, and without which we cannot hope for salvation. Hence, our most merciful Lord has bequeathed to His Church, Sacraments stamped with the sanction of His word and promise, through which, provided we make pious and devout use of these remedies, we firmly believe that the fruit of His Passion is really communicated to us.
A fourth reason why the institution of the Sacraments seems necessary is that there may be certain marks and symbols to distinguish the faithful; particularly since, as St. Augustine observes, no society of men, professing a true or a false religion, can be, so to speak, consolidated into one body, unless united and held together by some bond of sensible signs. Both these objects the Sacraments of the New Law accomplish, distinguishing the Christian from the infidel, and uniting the faithful by a sort of sacred bond.
Another very just cause for the institution of the Sacraments may be shown from the words of the Apostle: With the heart we believe unto justice; but with the mouth confession is made unto salvation. By approaching them we make a public profession of our faith in the sight of men. Thus, when we approach Baptism, we openly profess our belief that, by virtue of its salutary waters in which we are washed, the soul is spiritually cleansed.
The Sacraments have also great influence, not only in exciting and exercising our faith, but also in inflaming that charity with which we should love one another, when we recollect that, by partaking of these mysteries in common, we are knit together in the closest bonds and are made members of one body.
A final consideration, which is of greatest importance for the life of a Christian, is that the Sacraments repress and subdue the pride of the human heart, and exercise us in the practice of humility; for they oblige us to subject ourselves to sensible elements in obedience to God, from whom we had before impiously revolted in order to serve the elements of the world.
These are the chief points that appeared to us necessary for the instruction of the faithful on the name, nature, and institution of a Sacrament. When they shall have been accurately expounded by the pastor, his next duty will be to explain the constituents of each Sacrament, its parts, and the rites and ceremonies which have been added to its administration.
