Arcana Coelestia #478
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.

2046. 'Every male' means those who possess the truth of faith. This is clear from the meaning of 'a male' as truth, dealt with in 672, 749. The reason why the word 'male', meaning the truth of faith, is used is that nobody can be purified from those filthy loves except the person who is governed by truth. From truth he recognizes what is pure or impure, and what is holy or unholy. Until he possesses such knowledge there are no channels into which and through which heavenly love flowing in constantly from the Lord is able to operate, for it cannot be received except within truths. It is by means of cognitions of truth therefore that a person is reformed and regenerated, but this does not take place before he has been endowed with them. Conscience itself is formed by means of the truths of faith, for the conscience with which a regenerate person is endowed is a conscience for what is true and right. On this matter see 977, 986 (end), 1033, 1076, 1077. This also is the reason why flint knives, or 'swords of flint', as they are called, were used for circumcision. 'Swords of flint' means truths, see above 2039 (end).
