Summa Theologica I-II, q. 102: Of the Causes of the Ceremonial Precepts
To this Solomon refers (3 Kings 8:27) when he says: "If heaven and the heavens of heavens cannot contain Thee, how much less this house which I have built" for Thee? And further on (3 Kings 8:29, 30) he adds: "That Thy eyes may be open upon this house. . . of which Thou hast said: My name shall be there; . . . that Thou mayest hearken to the supplication of Thy servant and of Thy people Israel." From this it is evident that the house of the sanctuary was set up, not in order to contain God, as abiding therein locally, but that God might be made known there by means of things done and said there; and that those who prayed there might, through reverence for the place, pray more devoutly, so as to be heard more readily.
Reply to Objection 2Before the coming of Christ, the state of the Old Law was not changed as regards the fulfilment of the Law, which was effected in Christ alone: but it was changed as regards the condition of the people that were under the Law. Because, at first, the people were in the desert, having no fixed abode: afterwards they were engaged in various wars with the neighboring nations; and lastly, at the time of David and Solomon, the state of that people was one of great peace. And then for the first time the temple was built in the place which Abraham, instructed by God, had chosen for the purpose of sacrifice. For it is written (Gn. 22:2) that the Lord commanded Abraham to "offer" his son "for a holocaust upon one of the mountains which I will show thee": and it is related further on (Gn. 22:14) that "he calleth the name of that place, The Lord seeth," as though, according to the Divine prevision, that place were chosen for the worship of God. Hence it is written (Dt. 12:5,6): "You shall come to the place which the Lord your God shall choose. . . and you shall offer. . . your holocausts and victims."
Now it was not meet for that place to be pointed out by the building of the temple before the aforesaid time; for three reasons assigned by Rabbi Moses. First, lest the Gentiles might seize hold of that place. Secondly, lest the Gentiles might destroy it. The third reason is lest each tribe might wish that place to fall to their lot, and strifes and quarrels be the result. Hence the temple was not built until they had a king who would be able to quell such quarrels. Until that time a portable tabernacle was employed for divine worship, no place being as yet fixed for the worship of God. This is the literal reason for the distinction between the tabernacle and the temple.
The figurative reason may be assigned to the fact that they signify a twofold state. For the tabernacle, which was changeable, signifies the state of the present changeable life: whereas the temple, which was fixed and stable, signifies the state of future life which is altogether unchangeable. For this reason it is said that in the building of the temple no sound was heard of hammer or saw, to signify that all movements of disturbance will be far removed from the future state. Or else the tabernacle signifies the state of the Old Law; while the temple built by Solomon betokens the state of the New Law. Hence the Jews alone worked at the building of the tabernacle; whereas the temple was built with the cooperation of the Gentiles, viz. the Tyrians and Sidonians.
Reply to Objection 3The reason for the unity of the temple or tabernacle may be either literal or figurative. The literal reason was the exclusion of idolatry. For the Gentiles put up various temples to various gods: and so, to strengthen in the minds of men their belief in the unity of the Godhead, God wished sacrifices to be offered to Him in one place only. Another reason was in order to show that bodily worship is not acceptable of itself: and so they restrained from offering sacrifices anywhere and everywhere. But the worship of the New Law, in the sacrifice whereof spiritual grace is contained, is of itself acceptable to God; and consequently the multiplication of altars and temples is permitted in the New Law.
As to those matters that regarded the spiritual worship of God, consisting in the teaching of the Law and the Prophets, there were, even under the Old Law, various places, called synagogues, appointed for the people to gather together for the praise of God; just as now there are places called churches in which the Christian people gather together for the divine worship. Thus our church takes the place of both temple and synagogue: since the very sacrifice of the Church is spiritual; wherefore with us the place of sacrifice is not distinct from the place of teaching. The figurative reason may be that hereby is signified the unity of the Church, whether militant or triumphant.
Reply to Objection 4Just as the unity of the temple or tabernacle betokened the unity of God, or the unity of the Church, so also the division of the tabernacle or temple signified the distinction of those things that are subject to God, and from which we arise to the worship of God. Now the tabernacle was divided into two parts: one was called the "Holy of Holies," and was placed to the west; the other was called the "Holy Place", which was situated to the east. Moreover there was a court facing the tabernacle. Accordingly there are two reasons for this distinction. One is in respect of the tabernacle being ordained to the worship of God. Because the different parts of the world are thus betokened by the division of the tabernacle. For that part which was called the Holy of Holies signified the higher world, which is that of spiritual substances: while that part which is called the Holy Place signified the corporeal world. Hence the Holy Place was separated from the Holy of Holies by a veil, which was of four different colors (denoting the four elements), viz. of linen, signifying earth, because linen, i.e. flax, grows out of the earth; purple, signifying water, because the purple tint was made from certain shells found in the sea; violet, signifying air, because it has the color of the air; and scarlet twice dyed, signifying fire: and this because matter composed of the four elements is a veil between us and incorporeal substances. Hence the high-priest alone, and that once a year, entered into the inner tabernacle, i.e. the Holy of Holies: whereby we are taught that man's final perfection consists in his entering into that (higher) world: whereas into the outward tabernacle, i.e. the Holy Place, the priests entered every day: whereas the people were only admitted to the court; because the people were able to perceive material things, the inner nature of which only wise men by dint of study are able to discover.
