Of the Sacraments' Principal Effect, Which Is Grace

Of the Sacraments' Principal Effect, Which Is Grace — St. Thomas Aquinas asks: Whether the sacraments are the cause of grace?; Whether sacramental grace confers anything in addition to the grace of the virtues and gifts?; Whether the sacraments of the New Law contain grace?; Whether there be in the sacraments a power of causing grace?; Whether the sacraments of the New Law derive their power from Christ's Passion?; Whether the sacraments of the Old Law caused grace?.

We have now to consider the effect of the sacraments. First of their principal effect, which is grace; secondly, of their secondary effect, which is a character. Concerning the first there are six points of inquiry:

Article 1: Whether the sacraments are the cause of grace?

Augustine says (Tract. lxxx in Joan.) that the baptismal water "touches the body and cleanses the heart." But the heart is not cleansed save through grace. Therefore it causes grace: and for like reason so do the other sacraments of the Church.

We must needs say that in some way the sacraments of the New Law cause grace. For it is evident that through the sacraments of the New Law man is incorporated with Christ: thus the Apostle says of Baptism (Gal. 3:27): "As many of you as have been baptized in Christ have put on Christ." And man is made a member of Christ through grace alone.

Some, however, say that they are the cause of grace not by their own operation, but in so far as God causes grace in the soul when the sacraments are employed. And they give as an example a man who on presenting a leaden coin, receives, by the king's command, a hundred pounds: not as though the leaden coin, by any operation of its own, caused him to be given that sum of money; this being the effect of the mere will of the king. Hence Bernard says in a sermon on the Lord's Supper: "Just as a canon is invested by means of a book, an abbot by means of a crozier, a bishop by means of a ring, so by the various sacraments various kinds of grace are conferred." But if we examine the question properly, we shall see that according to the above mode the sacraments are mere signs. For the leaden coin is nothing but a sign of the king's command that this man should receive money. In like manner the book is a sign of the conferring of a canonry. Hence, according to this opinion the sacraments of the New Law would be mere signs of grace; whereas we have it on the authority of many saints that the sacraments of the New Law not only signify, but also cause grace.

We must therefore say otherwise, that an efficient cause is twofold, principal and instrumental. The principal cause works by the power of its form, to which form the effect is likened; just as fire by its own heat makes something hot. In this way none but God can cause grace: since grace is nothing else than a participated likeness of the Divine Nature, according to 2 Pet. 1:4: "He hath given us most great and precious promises; that we may be [Vulg.: 'you may be made'] partakers of the Divine Nature." But the instrumental cause works not by the power of its form, but only by the motion whereby it is moved by the principal agent: so that the effect is not likened to the instrument but to the principal agent: for instance, the couch is not like the axe, but like the art which is in the craftsman's mind. And it is thus that the sacraments of the New Law cause grace: for they are instituted by God to be employed for the purpose of conferring grace. Hence Augustine says (Contra Faust. xix): "All these things," viz. pertaining to the sacraments, "are done and pass away, but the power," viz. of God, "which works by them, remains ever." Now that is, properly speaking, an instrument by which someone works: wherefore it is written (Titus 3:5): "He saved us by the laver of regeneration."

Article 2: Whether sacramental grace confers anything in addition to the grace of the virtues and gifts?

If sacramental grace confers nothing in addition to the grace of the virtues and gifts, it is useless to confer the sacraments on those who have the virtues and gifts. But there is nothing useless in God's works. Therefore it seems that sacramental grace confers something in addition to the grace of the virtues and gifts.

As stated in the , grace, considered in itself, perfects the essence of the soul, in so far as it is a certain participated likeness of the Divine Nature. And just as the soul's powers flow from its essence, so from grace there flow certain perfections into the powers of the soul, which are called virtues and gifts, whereby the powers are perfected in reference to their actions. Now the sacraments are ordained unto certain special effects which are necessary in the Christian life: thus Baptism is ordained unto a certain spiritual regeneration, by which man dies to vice and becomes a member of Christ: which effect is something special in addition to the actions of the soul's powers: and the same holds true of the other sacraments. Consequently just as the virtues and gifts confer, in addition to grace commonly so called, a certain special perfection ordained to the powers' proper actions, so does sacramental grace confer, over and above grace commonly so called, and in addition to the virtues and gifts, a certain Divine assistance in obtaining the end of the sacrament. It is thus that sacramental grace confers something in addition to the grace of the virtues and gifts.

Article 3: Whether the sacraments of the New Law contain grace?

Hugh of S. Victor says (De Sacram. i) that "a sacrament, through its being sanctified, contains an invisible grace."

A thing is said to be in another in various ways; in two of which grace is said to be in the sacraments. First, as in its sign; for a sacrament is a sign of grace. Secondly, as in its cause; for, as stated above () a sacrament of the New Law is an instrumental cause of grace. Wherefore grace is in a sacrament of the New Law, not as to its specific likeness, as an effect in its univocal cause; nor as to some proper and permanent form proportioned to such an effect, as effects in non-univocal causes, for instance, as things generated are in the sun; but as to a certain instrumental power transient and incomplete in its natural being, as will be explained later on ().

Article 4: Whether there be in the sacraments a power of causing grace?

Augustine says (Tract. lxxx in Joan.): "Whence hath water so great power, that it touches the body and cleanses the heart?" And Bede says that "Our Lord conferred a power of regeneration on the waters by the contact of His most pure body."

Those who hold that the sacraments do not cause grace save by a certain coincidence, deny the sacraments any power that is itself productive of the sacramental effect, and hold that the Divine power assists the sacraments and produces their effect. But if we hold that a sacrament is an instrumental cause of grace, we must needs allow that there is in the sacraments a certain instrumental power of bringing about the sacramental effects. Now such power is proportionate to the instrument: and consequently it stands in comparison to the complete and perfect power of anything, as the instrument to the principal agent. For an instrument, as stated above (), does not work save as moved by the principal agent, which works of itself. And therefore the power of the principal agent exists in nature completely and perfectly: whereas the instrumental power has a being that passes from one thing into another, and is incomplete; just as motion is an imperfect act passing from agent to patient.

Article 5: Whether the sacraments of the New Law derive their power from Christ's Passion?

on Rom. 5:14: "After the similitude of the transgression of Adam," etc., the gloss says: "From the side of Christ asleep on the Cross flowed the sacraments which brought salvation to the Church." Consequently, it seems that the sacraments derive their power from Christ's Passion.

As stated above () a sacrament in causing grace works after the manner of an instrument. Now an instrument is twofold. the one, separate, as a stick, for instance; the other, united, as a hand. Moreover, the separate instrument is moved by means of the united instrument, as a stick by the hand. Now the principal efficient cause of grace is God Himself, in comparison with Whom Christ's humanity is as a united instrument, whereas the sacrament is as a separate instrument. Consequently, the saving power must needs be derived by the sacraments from Christ's Godhead through His humanity.

Now sacramental grace seems to be ordained principally to two things: namely, to take away the defects consequent on past sins, in so far as they are transitory in act, but endure in guilt; and, further, to perfect the soul in things pertaining to Divine Worship in regard to the Christian Religion. But it is manifest from what has been stated above (; ) that Christ delivered us from our sins principally through His Passion, not only by way of efficiency and merit, but also by way of satisfaction. Likewise by His Passion He inaugurated the Rites of the Christian Religion by offering "Himself---an oblation and a sacrifice to God" (Eph. 5:2). Wherefore it is manifest that the sacraments of the Church derive their power specially from Christ's Passion, the virtue of which is in a manner united to us by our receiving the sacraments. It was in sign of this that from the side of Christ hanging on the Cross there flowed water and blood, the former of which belongs to Baptism, the latter to the Eucharist, which are the principal sacraments.

Article 6: Whether the sacraments of the Old Law caused grace?

It is written (Gal. 4:9): "Turn you again to the weak and needy elements?" i.e. "to the Law," says the gloss, "which is called weak, because it does not justify perfectly." But grace justifies perfectly. Therefore the sacraments of the old Law did not confer grace.

It cannot be said that the sacraments of the Old Law conferred sanctifying grace of themselves, i.e. by their own power: since thus Christ's Passion would not have been necessary, according to Gal. 2:21: "If justice be by the Law, then Christ died in vain."

But neither can it be said that they derived the power of conferring sanctifying grace from Christ's Passion. For as it was stated above (), the power of Christ's Passion is united to us by faith and the sacraments, but in different ways; because the link that comes from faith is produced by an act of the soul; whereas the link that comes from the sacraments, is produced by making use of exterior things. Now nothing hinders that which is subsequent in point of time, from causing movement, even before it exists in reality, in so far as it pre-exists in an act of the soul: thus the end, which is subsequent in point of time, moves the agent in so far as it is apprehended and desired by him. On the other hand, what does not yet actually exist, does not cause movement if we consider the use of exterior things. Consequently, the efficient cause cannot in point of time come into existence after causing movement, as does the final cause. It is therefore clear that the sacraments of the New Law do reasonably derive the power of justification from Christ's Passion, which is the cause of man's righteousness; whereas the sacraments of the Old Law did not.

Nevertheless the Fathers of old were justified by faith in Christ's Passion, just as we are. And the sacraments of the old Law were a kind of protestation of that faith, inasmuch as they signified Christ's Passion and its effects. It is therefore manifest that the sacraments of the Old Law were not endowed with any power by which they conduced to the bestowal of justifying grace: and they merely signified faith by which men were justified.
