Reply Obj. 3: The 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 Obj. 4: Just 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" [*Or 'Sanctuary'. The Douay version uses both expressions], 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 perceived material things, the inner nature of which only wise men by dint of study are able to discover.
But with regard to the figurative reason, the outward tabernacle, which was called the Holy Place, betokened the state of the Old Law, as the Apostle says (Heb. 9:6, seqq.): because into that tabernacle "the priests always entered accomplishing the offices of sacrifices." But the inner tabernacle, which was called the Holy of Holies, signified either the glory of heaven or the spiritual state of the New Law to come. To the latter state Christ brought us; and this was signified by the high-priest entering alone, once a year, into the Holy of Holies. The veil betokened the concealing of the spiritual sacrifices under the sacrifices of old. This veil was adorned with four colors: viz. that of linen, to designate purity of the flesh; purple, to denote the sufferings which the saints underwent for God; scarlet twice dyed, signifying the twofold love of God and our neighbor; and violet, in token of heavenly contemplation. With regard to the state of the Old Law the people and the priests were situated differently from one another. For the people saw the mere corporeal sacrifices which were offered in the court: whereas the priests were intent on the inner meaning of the sacrifices, because their faith in the mysteries of Christ was more explicit. Hence they entered into the outer tabernacle. This outer tabernacle was divided from the court by a veil; because some matters relating to the mystery of Christ were hidden from the people, while they were known to the priests: though they were not fully revealed to them, as they were subsequently in the New Testament (cf. Eph. 3:5).
Reply Obj. 5: Worship towards the west was introduced in the Law to the exclusion of idolatry: because all the Gentiles, in reverence to the sun, worshipped towards the east; hence it is written (Ezech. 8:16) that certain men "had their backs towards the temple of the Lord, and their faces to the east, and they adored towards the rising of the sun." Accordingly, in order to prevent this, the tabernacle had the Holy of Holies to westward, that they might adore toward the west. A figurative reason may also be found in the fact that the whole state of the first tabernacle was ordained to foreshadow the death of Christ, which is signified by the west, according to Ps. 67:5: "Who ascendeth unto the west; the Lord is His name."
Reply Obj. 6: Both literal and figurative reasons may be assigned for the things contained in the tabernacle. The literal reason is in connection with the divine worship. And because, as already observed (ad 4), the inner tabernacle, called the Holy of Holies, signified the higher world of spiritual substances, hence that tabernacle contained three things, viz. "the ark of the testament in which was a golden pot that had manna, and the rod of Aaron that had blossomed, and the tables" (Heb. 9:4) on which were written the ten commandments of the Law. Now the ark stood between two "cherubim" that looked one towards the other: and over the ark was a table, called the "propitiatory," raised above the wings of the cherubim, as though it were held up by them; and appearing, to the imagination, to be the very seat of God. For this reason it was called the "propitiatory," as though the people received propitiation thence at the prayers of the high-priest. And so it was held up, so to speak, by the cherubim, in obedience, as it were, to God: while the ark of the testament was like the foot-stool to Him that sat on the propitiatory. These three things denote three things in that higher world: namely, God Who is above all, and incomprehensible to any creature. Hence no likeness of Him was set up; to denote His invisibility. But there was something to represent his seat; since, to wit, the creature, which is beneath God, as the seat under the sitter, is comprehensible. Again in that higher world there are spiritual substances called angels. These are signified by the two cherubim, looking one towards the other, to show that they are at peace with one another, according to Job 25:2: "Who maketh peace in . . . high places." For this reason, too, there was more than one cherub, to betoken the multitude of heavenly spirits, and to prevent their receiving worship from those who had been commanded to worship but one God. Moreover there are, enclosed as it were in that spiritual world, the intelligible types of whatsoever takes place in this world, just as in every cause are enclosed the types of its effects, and in the craftsman the types of the works of his craft. This was betokened by the ark, which represented, by means of the three things it contained, the three things of greatest import in human affairs. These are wisdom, signified by the tables of the testament; the power of governing, betokened by the rod of Aaron; and life, betokened by the manna which was the means of sustenance. Or else these three things signified the three Divine attributes, viz. wisdom, in the tables; power, in the rod; goodness, in the manna—both by reason of its sweetness, and because it was through the goodness of God that it was granted to man, wherefore it was preserved as a memorial of the Divine mercy. Again, these three things were represented in Isaias' vision. For he "saw the Lord sitting upon a throne high and elevated"; and the seraphim standing by; and that the house was filled with the glory of the Lord; wherefrom the seraphim cried out: "All the earth is full of His glory" (Isa. 6:1, 3). And so the images of the seraphim were set up, not to be worshipped, for this was forbidden by the first commandment; but as a sign of their function, as stated above.
The outer tabernacle, which denotes this present world, also contained three things, viz. the "altar of incense," which was directly opposite the ark; the "table of proposition," with the twelve loaves of proposition on it, which stood on the northern side; and the "candlestick," which was placed towards the south. These three things seem to correspond to the three which were enclosed in the ark; and they represented the same things as the latter, but more clearly: because, in order that wise men, denoted by the priests entering the temple, might grasp the meaning of these types, it was necessary to express them more manifestly than they are in the Divine or angelic mind. Accordingly the candlestick betokened, as a sensible sign thereof, the wisdom which was expressed on the tables (of the Law) in intelligible words. The altar of incense signified the office of the priest, whose duty it was to bring the people to God: and this was signified also by the rod: because on that altar the sweet-smelling incense was burnt, signifying the holiness of the people acceptable to God: for it is written (Apoc. 8:3) that the smoke of the sweet-smelling spices signifies the "justifications of the saints" (cf. Apoc. 19:8). Moreover it was fitting that the dignity of the priesthood should be denoted, in the ark, by the rod, and, in the outer tabernacle, by the altar of incense: because the priest is the mediator between God and the people, governing the people by Divine power, denoted by the rod; and offering to God the fruit of His government, i.e. the holiness of the people, on the altar of incense, so to speak. The table signified the sustenance of life, just as the manna did: but the former, a more general and a coarser kind of nourishment; the latter, a sweeter and more delicate. Again, the candlestick was fittingly placed on the southern side, while the table was placed to the north: because the south is the right-hand side of the world, while the north is the left-hand side, as stated in De Coelo et Mundo ii; and wisdom, like other spiritual goods, belongs to the right hand, while temporal nourishment belongs on the left, according to Prov. 3:16: "In her left hand (are) riches and glory." And the priestly power is midway between temporal goods and spiritual wisdom; because thereby both spiritual wisdom and temporal goods are dispensed.
Another literal signification may be assigned. For the ark contained the tables of the Law, in order to prevent forgetfulness of the Law, wherefore it is written (Ex. 24:12): "I will give thee two tables of stone, and the Law, and the commandments which I have written: that thou mayest teach them" to the children of Israel. The rod of Aaron was placed there to restrain the people from insubordination to the priesthood of Aaron; wherefore it is written (Num. 17:10): "Carry back the rod of Aaron into the tabernacle of the testimony, that it may be kept there for a token of the rebellious children of Israel." The manna was kept in the ark to remind them of the benefit conferred by God on the children of Israel in the desert; wherefore it is written (Ex. 16:32): "Fill a gomor of it, and let it be kept unto generations to come hereafter, that they may know the bread wherewith I fed you in the wilderness." The candlestick was set up to enhance the beauty of the temple, for the magnificence of a house depends on its being well lighted. Now the candlestick had seven branches, as Josephus observes (Antiquit. iii, 7, 8), to signify the seven planets, wherewith the whole world is illuminated. Hence the candlestick was placed towards the south; because for us the course of the planets is from that quarter. The altar of incense was instituted that there might always be in the tabernacle a sweet-smelling smoke; both through respect for the tabernacle, and as a remedy for the stenches arising from the shedding of blood and the slaying of animals. For men despise evil-smelling things as being vile, whereas sweet-smelling things are much appreciated. The table was placed there to signify that the priests who served the temple should take their food in the temple: wherefore, as stated in Matt. 12:4, it was lawful for none but the priests to eat the twelve loaves which were put on the table in memory of the twelve tribes. And the table was not placed in the middle directly in front of the propitiatory, in order to exclude an idolatrous rite: for the Gentiles, on the feasts of the moon, set up a table in front of the idol of the moon, wherefore it is written (Jer. 7:18): "The women knead the dough, to make cakes to the queen of heaven."
In the court outside the tabernacle was the altar of holocausts, on which sacrifices of those things which the people possessed were offered to God: and consequently the people who offered these sacrifices to God by the hands of the priest could be present in the court. But the priests alone, whose function it was to offer the people to God, could approach the inner altar, whereon the very devotion and holiness of the people was offered to God. And this altar was put up outside the tabernacle and in the court, to the exclusion of idolatrous worship: for the Gentiles placed altars inside the temples to offer up sacrifices thereon to idols.
The figurative reason for all these things may be taken from the relation of the tabernacle to Christ, who was foreshadowed therein. Now it must be observed that to show the imperfection of the figures of the Law, various figures were instituted in the temple to betoken Christ. For He was foreshadowed by the "propitiatory," since He is "a propitiation for our sins" (1 John 2:2). This propitiatory was fittingly carried by cherubim, since of Him it is written (Heb. 1:6): "Let all the angels of God adore Him." He is also signified by the ark: because just as the ark was made of setim-wood, so was Christ's body composed of most pure members. More over it was gilded: for Christ was full of wisdom and charity, which are betokened by gold. And in the ark was a golden pot, i.e. His holy soul, having manna, i.e. "all the fulness of the Godhead" (Col. 2:9). Also there was a rod in the ark, i.e. His priestly power: for "He was made a . . . priest for ever" (Heb. 6:20). And therein were the tables of the Testament, to denote that Christ Himself is a lawgiver. Again, Christ was signified by the candlestick, for He said Himself (John 8:12): "I am the Light of the world"; while the seven lamps denoted the seven gifts of the Holy Ghost. He is also betokened in the table, because He is our spiritual food, according to John 6:41, 51: "I am the living bread": and the twelve loaves signified the twelve apostles, or their teaching. Or again, the candlestick and table may signify the Church's teaching, and faith, which also enlightens and refreshes. Again, Christ is signified by the two altars of holocausts and incense. Because all works of virtue must be offered to us to God through Him; both those whereby we afflict the body, which are offered, as it were, on the altar of holocausts; and those which, with greater perfection of mind, are offered to God in Christ, by the spiritual desires of the perfect, on the altar of incense, as it were, according to Heb. 13:15: "By Him therefore let us offer the sacrifice of praise always to God."
