The woman clothed, or encompassed, with the sun, and the moon under her feet (Revelation 12:1), signifies the Lord's new church in the heavens, which is the new heaven, and the Lord's new church about to be upon earth, which is the New Jerusalem.

That the Lord's new church is signified by this woman, appears from all the particulars of this chapter, understood in a spiritual sense. The sun signifies love. The reason why she appeared encompassed with the sun is because the church is principled in love to the Lord, for it acknowledges him, and does his commandments, and this is to love him (John 14:21-24).

The reason why the moon was seen under the woman's feet is because the church on earth is meant, which is not yet conjoined with the church in the heavens. The moon signifies intelligence in the natural man, and faith; and by appearing under the feet is signified that it is about to be upon earth.
