A Brief Exposition of New Church Doctrine # 77
77. XVIII. That neither Love, nor Faith, nor the Cognitions of Good and Truth, exist in the last period of the Christian Church when it draws to its end, is meant by these words in the aforesaid chapter of Matthew:
After the tribulation of those days, shall the sun be darkened and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken. Matthew 24:29.
Apocalypse Revealed # 423
423. And the sun and the air were darkened because of the smoke of the pit. This symbolically means that therefore the light of truth became thick darkness.
The sun and the air here symbolize the light of truth, for the sun symbolizes love, and the light from it, Divine truth. Consequently, when we are told that the sun was darkened, and with it the air, it symbolically means that Divine truth became thick darkness. That this resulted from falsities accompanying lusts is symbolically meant by its being because of the smoke of the pit.
