478. The reason he is called Adam is that the Hebrew word Adam means man. But the fact that Adam was never used as a proper name, only Man, is quite clear from the consideration that both here and earlier he is spoken of in the plural and not in the singular, and that the term refers to both man and woman. The two together are called Man. Anyone may see from these words that both are included, for it is said, 'He called their name Man on the day in which they were created', and similarly in 1:26, 28, 'Let Us make man in Our image, and they will have dominion over the fish of the sea. This shows also that the subject is not about someone who, when created, was the first human being of all, but about the Most Ancient Church.

5846. THE PRESENCE OF SPIRITS AND ANGELS
THE SPIRITS AND ANGELS PRESENT WITH A PERSON
Considered generally the inflow from the spiritual world into a person is as follows: There is nothing that a person thinks or wills that can originate within himself. Rather, everything flows into him; goodness and truth flow in from the Lord by way of heaven, thus through the angels present with the person, evil and falsity from hell, thus through the evil spirits present with him. And what flows in enters his thought and will. I realize that this will appear to be utter nonsense because it is contrary to the appearance; but actual experience will settle the truth of the matter.
