In Revelation 18:13, 'wine, oil, flour, and wheat' signify celestial principles of worship.

(References: Apocalypse Revealed 777)

777. 18:13 "And cinnamon, fragrances, ointment and frankincense." This symbolically means that these Roman Catholics no longer have any worship that springs from spiritual goods and truths, because they have nothing inwardly in their worship that corresponds to the aforesaid things.

The preceding verse had as it subject everything having to do with the church's doctrine. Now this verse has as its subject everything having to do with the church's worship.

Things having to do with doctrine are put first, and things having to do with worship follow, since worship has its character from the goods and truths of doctrine. For the church's worship is nothing but an outward act whose internal elements ought to be those of doctrine. Without them the worship is lacking its essence, life and soul.

Now because everything having to do with doctrine has relation to goods that are matters of love and charity and to truths that are matters of wisdom and faith, and these goods and truths are celestial, spiritual, or natural, according to the degrees of their succession, so too are all the ingredients of worship. Moreover, because the preceding verse mentions spiritual things having to do with doctrine first, so this verse mentions spiritual things having to do with worship first, namely cinnamon, fragrances, ointment and frankincense, and secondly then celestial things having to do with worship, namely wine, oil, flour and wheat, and thirdly natural things having to do with worship, namely cattle and sheep. That all these goods and truths having to do with worship must come from the Word is symbolized by their being merchandise of horses and wagons and the bodies and souls of people. This is the sequence of subjects in the spiritual sense of this verse.

All the valuables listed in this verse have the same meaning as the valuables listed in the preceding verse, namely, that these goods and truths are lacking in these Roman Catholics, because they do not have in them the goods and truths that correspond to the things listed. This is apparent from preceding verses, where we are told that the city Babylon will be burned with fire and that no one will buy her merchandise anymore (verses 8-11). It is apparent also from verses that follow, where we are told that all things rich and splendid have gone from her and shall be found no more (verse 14), and that they were destroyed (verses 16, 19).

[2] Now, however, we must say something about the valuables listed here, namely cinnamon, fragrances, ointment and frankincense. These are specified because they are the ingredients used in making incense. Incense symbolizes a worship of the Lord that springs from spiritual goods and truths, as may be seen in nos. 277, 392 above. And incense offerings were pleasing because they consisted of fragrant ingredients that corresponded to those goods and truths, as may be seen in no. 394.

All the fragrant ingredients used in the preparation of incense are meant by cinnamon, fragrances, and ointment, and their base by frankincense. This is apparent from the list in Exodus of the aromatic ingredients of which it was made:

Jehovah said to Moses: "Take sweet spices - stacte, onycha and galbanum - ...and pure frankincense... And you shall make of these a fragrance, an ointment the work of a perfumer, salted, pure, and holy. (Exodus 30:34-37)

They used these ingredients to make incense, which, as we said, symbolized a worship springing from spiritual goods and truths. Cinnamon is substituted here for all the fragrant ingredients listed there.

What each of these aromatic ingredients symbolizes in the spiritual sense may be seen in Arcana Coelestia (The Secrets of Heaven), in the treatment of Exodus where they are explained one by one.
