Of the Necessity of the Sacraments

Of the Necessity of the Sacraments — St. Thomas Aquinas asks: Whether sacraments are necessary for man's salvation?; Whether before sin sacraments were necessary to man?; Whether there should have been sacraments after sin, before Christ?; Whether there was need for any sacraments after Christ came?.

We must now consider the necessity of the sacraments; concerning which there are four points of inquiry:

Article 1: Whether sacraments are necessary for man's salvation?

Augustine says (Contra Faust. xix): "It is impossible to keep men together in one religious denomination, whether true or false, except they be united by means of visible signs or sacraments." But it is necessary for salvation that men be united together in the name of the one true religion. Therefore sacraments are necessary for man's salvation.

Sacraments are necessary unto man's salvation for three reasons. The first is taken from the condition of human nature which is such that it has to be led by things corporeal and sensible to things spiritual and intelligible. Now it belongs to Divine providence to provide for each one according as its condition requires. Divine wisdom, therefore, fittingly provides man with means of salvation, in the shape of corporeal and sensible signs that are called sacraments.

The second reason is taken from the state of man who in sinning subjected himself by his affections to corporeal things. Now the healing remedy should be given to a man so as to reach the part affected by disease. Consequently it was fitting that God should provide man with a spiritual medicine by means of certain corporeal signs; for if man were offered spiritual things without a veil, his mind being taken up with the material world would be unable to apply itself to them.

The third reason is taken from the fact that man is prone to direct his activity chiefly towards material things. Lest, therefore, it should be too hard for man to be drawn away entirely from bodily actions, bodily exercise was offered to him in the sacraments, by which he might be trained to avoid superstitious practices, consisting in the worship of demons, and all manner of harmful action, consisting in sinful deeds.

It follows, therefore, that through the institution of the sacraments man, consistently with his nature, is instructed through sensible things; he is humbled, through confessing that he is subject to corporeal things, seeing that he receives assistance through them: and he is even preserved from bodily hurt, by the healthy exercise of the sacraments.

Article 2: Whether before sin sacraments were necessary to man?

None but the sick need remedies, according to Mat. 9:12: "They that are in health need not a physician." Now the sacraments are spiritual remedies for the healing of wounds inflicted by sin. Therefore they were not necessary before sin.

Sacraments were not necessary in the state of innocence. This can be proved from the rectitude of that state, in which the higher (parts of man) ruled the lower, and nowise depended on them: for just as the mind was subject to God, so were the lower powers of the soul subject to the mind, and the body to the soul. And it would be contrary to this order if the soul were perfected either in knowledge or in grace, by anything corporeal; which happens in the sacraments. Therefore in the state of innocence man needed no sacraments, whether as remedies against sin or as means of perfecting the soul.

Article 3: Whether there should have been sacraments after sin, before Christ?

Augustine says (Contra Faust. xix) that "the first sacraments which the Law commanded to be solemnized and observed were announcements of Christ's future coming." But it was necessary for man's salvation that Christ's coming should be announced beforehand. Therefore it was necessary that some sacraments should be instituted before Christ.

Sacraments are necessary for man's salvation, in so far as they are sensible signs of invisible things whereby man is made holy. Now after sin no man can be made holy save through Christ, "Whom God hath proposed to be a propitiation, through faith in His blood, to the showing of His justice . . . that He Himself may be just, and the justifier of him who is of the faith of Jesus Christ" (Rom. 3:25,26). Therefore before Christ's coming there was need for some visible signs whereby man might testify to his faith in the future coming of a Saviour. And these signs are called sacraments. It is therefore clear that some sacraments were necessary before Christ's coming.

Article 4: Whether there was need for any sacraments after Christ came?

Augustine says (Contra Faust. xix) that the sacraments of the Old Law "were abolished because they were fulfilled; and others were instituted, fewer in number, but more efficacious, more profitable, and of easier accomplishment."

As the ancient Fathers were saved through faith in Christ's future coming, so are we saved through faith in Christ's past birth and Passion. Now the sacraments are signs in protestation of the faith whereby man is justified; and signs should vary according as they signify the future, the past, or the present; for as Augustine says (Contra Faust. xix), "the same thing is variously pronounced as to be done and as having been done: for instance the word 'passurus' [going to suffer] differs from 'passus' [having suffered]." Therefore the sacraments of the New Law, that signify Christ in relation to the past, must needs differ from those of the Old Law, that foreshadowed the future.
