775. "Every vessel of precious wood, bronze, iron, and marble." This symbolically means that these Roman Catholics no longer have these because they do not have any knowledge of the goods and truths in ecclesiastical affairs to which such things correspond.

This statement is similar to the ones explained in nos. 772, 773, and 774 above. The difference is that the valuables here are various forms of knowledge, which are the lowest ones in a person's natural mind. And because they differ in character owing to the essence that lies within them, they are called vessels of precious wood, bronze, iron, and marble. For vessels symbolize forms of knowledge, here forms of knowledge in ecclesiastical affairs. Because various forms of knowledge are the containing vessels of goodness and truth, they are like vessels containing oil or wine.

Forms of knowledge are also found in great variety, and their recipient vessel is the memory. They are of great variety because they contain the interior elements of a person. They are also introduced into the memory either by intellectual deliberation or by hearing or reading them, according to the varying perception then of the rational mind. All of these things are present in forms of knowledge, as is apparent when they are reproduced, which is the case when a person speaks or thinks.

[2] But we will briefly say what vessels of precious wood, bronze, iron and marble symbolize. A vessel of precious wood symbolizes something known as the result of rational goodness and truth. A vessel of bronze symbolizes something known as the result of natural goodness. A vessel of iron symbolizes something known as the result of natural truth. And a vessel of marble symbolizes something known as the result of an appearance of goodness and truth.

That wood symbolizes goodness may be seen just above in no. 774. That precious wood here symbolizes both rational goodness and rational truth is due to the fact that wood symbolizes goodness, and preciousness is predicated of truth. For one variety of goodness is symbolized by the wood of the olive tree, another by the wood of the cedar, of the fig tree, of the fir tree, of the poplar and of the oak.

A vessel of bronze and iron symbolizes something known as the result of natural goodness and truth, because all metals, such as gold, silver, bronze, iron, tin, and lead, in the Word symbolize goods and truths. They symbolize because they correspond, and because they correspond they are also found in heaven. For everything in heaven is a correspondent form.

[3] However, this is not the place to confirm from the Word what each kind of metal symbolizes owing to its correspondence. We will cite only some passages to confirm that bronze symbolizes natural goodness, and iron, therefore, natural truth, as can be seen from the following: That the feet of the Son of Man looked like bronze, as though fired in a furnace (Revelation 1:15). That Daniel saw a man whose feet were like the gleam of burnished bronze (Daniel 10:5-6).

That the feet of cherubim were seen sparking as with the gleam of burnished bronze (Ezekiel 1:7). (Feet symbolize something natural, as may be seen in nos. 49, 468, 470, 510.) That an angel appears whose appearance was like the appearance of bronze (Ezekiel 40:3). And that the statue Nebuchadnezzar saw was as to its head golden, as to its breast and arms silver, as to its belly and sides bronze, and as to its legs iron (Daniel 2:32-33). The statue represented the successive states of the church which the ancients called the golden age, silver age, bronze age, and iron age.

Since bronze symbolizes something natural, and the Israelite people were purely natural, therefore the Lord's natural humanity was represented by the bronze serpent, which people bitten by serpents had only to look at to be cured (Numbers 21:6, 8-9).

That bronze symbolizes natural goodness may also be seen in Isaiah 60:17, Jeremiah 15:20-21, Ezekiel 27:13, Deuteronomy 8:7, 9, 33:24-25

231. And He who sat there was like a jasper and a sardius stone in appearance. (4:3) This symbolizes an appearance of the Lord's Divine wisdom and love in outmost expressions.

In the Word a stone symbolizes truth in outmost expressions, and a precious stone symbolizes truth made translucent by the presence of good (no. 915).

Two colors are fundamental to all the rest in the spiritual world: the color white and the color red. The color white takes its origin from the light of the sun in heaven, thus from spiritual light, which is bright white; and the color red takes its origin from the fire of the sun there, thus from celestial light, which is flaming.

Because spiritual angels are governed by truths of wisdom from the Lord, they live in that bright white light, and are therefore attired in white; and because celestial angels are governed by goods of love from the Lord, they live in that flaming light, and are therefore attired in red. These two colors are consequently found in precious stones in heaven, where they exist in great abundance.

It is owing to this that in the Word precious stones symbolize qualities connected with either the truth of wisdom or the goodness of love; and because jasper is bright white, it symbolizes qualities connected with the truth of wisdom, while because sardius is red, it symbolizes qualities connected with the goodness of love.

These stones symbolize an appearance of Divine wisdom and Divine love in outmost expressions because all precious stones in heaven draw their origin from the outmost constituents of the Word, and they owe their translucence to the spiritual meaning of the outmost expressions in it. The reality of this may be seen in The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 44, 45. The outmost expressions of the Word are the truths and goods in its literal sense.

Someone in our world can hardly believe that this is the origin of precious stones in heaven, because he does not know that everything found in the spiritual world is a correspondent form, and that everything found in the natural world takes its spiritual origin from those forms. From conversation with angels I have been given to know that this is the origin of precious stones in heaven, and also to see that it is the origin with my own eyes. It is the Lord alone, however, who causes their formation.

In contrast, dark colors take their origin from hell, of which there are also two. One is the opposite of white, the kind of darkness that exists with people who have falsified the truths of the Word. The other is the opposite of red, the kind of darkness that exists with those who have adulterated the goods of the Word. The first kind of darkness is satanic, the latter diabolical.

Regarding what jasper and sardius symbolize, more may be seen in the exposition of chapter 21, verses 11, 18-20.
