805. All in whose nostrils was the breathing of the breath of lives. That this signifies the men who were of the Most Ancient Church in whose nostrils was the breathing of the breath of lives, that is, the life of love and of the derivative faith, is evident from what has been said before (n. 96, 97). Among the most ancient people, life was signified by the "breath in the nostrils" or by "breathing" which is the life of the body corresponding to spiritual things, as the motion of the heart is the life of the body corresponding to celestial things.
[2] It is here said, "in whose nostrils was the breathing of the breath of lives" because the antediluvians are treated of, in whom by inheritance from their progenitors there was seed from the celestial, but extinct or suffocated. There is also a deeper meaning that lies hidden in these words, of which we have already spoken (n. 97), namely, that the man of the Most Ancient Church had internal respiration, and thus respiration concordant with and similar to that of angels, concerning which, of the Lord's Divine mercy hereafter. This respiration was varied in accordance with all the states of the internal man. But in process of time it was changed in their posterity, until this last generation, wherein all that was angelic perished. Then they could no longer respire with the angelic heaven. This was the real cause of their extinction; and therefore it is now said that they "expired" and that they in whose nostrils was the breathing of the breath of lives, "died."
[3] After these times internal respiration ceased, and with it communication with heaven and thereby celestial perception, and external respiration succeeded. And because communication with heaven thus ceased, the men of the Ancient (or new) Church could no longer be celestial men like the Most Ancient, but were spiritual. But concerning these things, of the Lord's Divine mercy hereafter.
