Of the Number of the Sacraments

I answer that, As stated above (Q. 62, A. 5; Q. 63, A. 1), the sacraments of the Church were instituted for a twofold purpose: namely, in order to perfect man in things pertaining to the worship of God according to the religion of Christian life, and to be a remedy against the defects caused by sin. And in either way it is becoming that there should be seven sacraments.

For spiritual life has a certain conformity with the life of the body: just as other corporeal things have a certain likeness to things spiritual. Now a man attains perfection in the corporeal life in two ways: first, in regard to his own person; secondly, in regard to the whole community of the society in which he lives, for man is by nature a social animal. With regard to himself man is perfected in the life of the body, in two ways; first, directly (per se), i.e. by acquiring some vital perfection; secondly, indirectly (per accidens), i.e. by the removal of hindrances to life, such as ailments, or the like. Now the life of the body is perfected directly, in three ways. First, by generation whereby a man begins to be and to live: and corresponding to this in the spiritual life there is Baptism, which is a spiritual regeneration, according to Titus 3:5: "By the laver of regeneration," etc. Secondly, by growth whereby a man is brought to perfect size and strength: and corresponding to this in the spiritual life there is Confirmation, in which the Holy Ghost is given to strengthen us. Wherefore the disciples who were already baptized were bidden thus: "Stay you in the city till you be endued with power from on high" (Luke 24:49). Thirdly, by nourishment, whereby life and strength are preserved to man; and corresponding to this in the spiritual life there is the Eucharist. Wherefore it is said (John 6:54): "Except you eat of the flesh of the Son of Man, and drink His blood, you shall not have life in you."

And this would be enough for man if he had an impassible life, both corporally and spiritually; but since man is liable at times to both corporal and spiritual infirmity, i.e. sin, hence man needs a cure from his infirmity; which cure is twofold. One is the healing, that restores health: and corresponding to this in the spiritual life there is Penance, according to Ps. 40:5: "Heal my soul, for I have sinned against Thee." The other is the restoration of former vigor by means of suitable diet and exercise: and corresponding to this in the spiritual life there is Extreme Unction, which removes the remainder of sin, and prepares man for final glory. Wherefore it is written (James 5:15): "And if he be in sins they shall be forgiven him."

In regard to the whole community, man is perfected in two ways. First, by receiving power to rule the community and to exercise public acts: and corresponding to this in the spiritual life there is the sacrament of order, according to the saying of Heb. 7:27, that priests offer sacrifices not for themselves only, but also for the people. Secondly in regard to natural propagation. This is accomplished by Matrimony both in the corporal and in the spiritual life: since it is not only a sacrament but also a function of nature.

We may likewise gather the number of the sacraments from their being instituted as a remedy against the defect caused by sin. For Baptism is intended as a remedy against the absence of spiritual life; Confirmation, against the infirmity of soul found in those of recent birth; the Eucharist, against the soul's proneness to sin; Penance, against actual sin committed after baptism; Extreme Unction, against the remainders of sins—of those sins, namely, which are not sufficiently removed by Penance, whether through negligence or through ignorance; order, against divisions in the community; Matrimony, as a remedy against concupiscence in the individual, and against the decrease in numbers that results from death.

Some, again, gather the number of sacraments from a certain adaptation to the virtues and to the defects and penal effects resulting from sin. They say that Baptism corresponds to Faith, and is ordained as a remedy against original sin; Extreme Unction, to Hope, being ordained against venial sin; the Eucharist, to Charity, being ordained against the penal effect which is malice; Order, to Prudence, being ordained against ignorance; Penance to Justice, being ordained against mortal sin; Matrimony, to Temperance, being ordained against concupiscence; Confirmation, to Fortitude, being ordained against infirmity.

I answer that, The reason of the order among the sacraments appears from what has been said above (A. 1). For just as unity precedes multitude, so those sacraments which are intended for the perfection of the individual, naturally precede those which are intended for the perfection of the multitude; and consequently the last place among the sacraments is given to order and Matrimony, which are intended for the perfection of the multitude: while Matrimony is placed after order, because it has less participation in the nature of the spiritual life, to which the sacraments are ordained. Moreover, among things ordained to the perfection of the individual, those naturally come first which are ordained directly to the perfection of the spiritual life, and afterwards, those which are ordained thereto indirectly, viz. by removing some supervening accidental cause of harm; such are Penance and Extreme Unction: while, of these, Extreme Unction is naturally placed last, for it preserves the healing which was begun by Penance.

Of the remaining three, it is clear that Baptism which is a spiritual regeneration, comes first; then Confirmation, which is ordained to the formal perfection of power; and after these the Eucharist which is ordained to final perfection.

I answer that, Absolutely speaking, the sacrament of the Eucharist is the greatest of all the sacraments: and this may be shown in three ways. First of all because it contains Christ Himself substantially: whereas the other sacraments contain a certain instrumental power which is a share of Christ's power, as we have shown above (Q. 62, A. 4, ad 3, A. 5). Now that which is essentially such is always of more account than that which is such by participation.

Secondly, this is made clear by considering the relation of the sacraments to one another. For all the other sacraments seem to be ordained to this one as to their end. For it is manifest that the sacrament of order is ordained to the consecration of the Eucharist: and the sacrament of Baptism to the reception of the Eucharist: while a man is perfected by Confirmation, so as not to fear to abstain from this sacrament. By Penance and Extreme Unction man is prepared to receive the Body of Christ worthily. And Matrimony at least in its signification, touches this sacrament; in so far as it signifies the union of Christ with the Church, of which union the Eucharist is a figure: hence the Apostle says (Eph. 5:32): "This is a great sacrament: but I speak in Christ and in the Church."

Thirdly, this is made clear by considering the rites of the sacraments. For nearly all the sacraments terminate in the Eucharist, as Dionysius says (Eccl. Hier. iii): thus those who have been ordained receive Holy Communion, as also do those who have been baptized, if they be adults.

The remaining sacraments may be compared to one another in several ways. For on the ground of necessity, Baptism is the greatest of the sacraments; while from the point of view of perfection, order comes first; while Confirmation holds a middle place. The sacraments of Penance and Extreme Unction are on a degree inferior to those mentioned above; because, as stated above (A. 2), they are ordained to the Christian life, not directly, but accidentally, as it were, that is to say, as remedies against supervening defects. And among these, Extreme Unction is compared to Penance, as Confirmation to Baptism; in such a way, that Penance is more necessary, whereas Extreme Unction is more perfect.

I answer that, Necessity of end, of which we speak now, is twofold. First, a thing may be necessary so that without it the end cannot be attained; thus food is necessary for human life. And this is simple necessity of end. Secondly, a thing is said to be necessary, if, without it, the end cannot be attained so becomingly: thus a horse is necessary for a journey. But this is not simple necessity of end.

In the first way, three sacraments are necessary for salvation. Two of them are necessary to the individual; Baptism, simply and absolutely; Penance, in the case of mortal sin committed after Baptism; while the sacrament of order is necessary to the Church, since "where there is no governor the people shall fall" (Prov. 11:14).

But in the second way the other sacraments are necessary. For in a sense Confirmation perfects Baptism; Extreme Unction perfects Penance; while Matrimony, by multiplying them, preserves the numbers in the Church.
