Arcana Coelestia #476
476. That 'male and female' means the marriage of faith and love has been stated and shown already. That is to say, 'male' or man (vir) means the understanding and what belongs to the understanding, and so what belongs to faith, while 'female' means the will, or what belongs to the will, and so what belongs to love. This also is why she was called Eve, from a word meaning life, which belongs to love alone. 'Female' therefore also means the Church, as also shown already, and 'male' the man (vir) of the Church. At present the subject is the state of the Church at the time it was spiritual and shortly to become celestial, which is why the word 'male' comes first, as it does also in 1:26-27. Furthermore the expression 'to create' has regard to the spiritual man. As soon however as that marriage has taken place, that is, the Church has become celestial, it is no longer called 'male and female' but 'Man' (Homo) who by virtue of the marriage means both. Consequently 'and He called their name Man', which means the Church, follows next.

35. Man has two inherent powers of will and understanding. When the understanding is governed by the will they then constitute one mind and so one life; for what a person in that case wills and does he also thinks and intends. But when the understanding is at variance with the will, as it is with people who claim to have faith and yet live otherwise, then a mind previously one is split in two. One half seeks to transport itself into heaven, while the other inclines towards hell. And because the will is what accomplishes everything, the whole man would rush straight into hell unless the Lord took pity on him.
