28. The Son of man symbolizes the Lord in relation to the Word because prophets also were called sons of man. Prophets were also called sons of man because they represented the Lord in relation to the Word, and therefore they symbolized the doctrine of the church drawn from the Word. Prophets have no other meaning in heaven when they are mentioned in the Word. For the spiritual meaning of a prophet, as also that of the Son of man, is the doctrine of the church drawn from the Word, and when referring to the Lord it is the Word itself.

That the prophet Daniel was called son of man may be seen in Daniel 8:17.

That the prophet Ezekiel was called son of man may be seen in Ezekiel 2:1, 3, 6, 8, 3:1, 3-4, 10, 17, 25, 4:1, 16, 5:1, 6:2, 7:2, 8:5-6, 8, 12, 15, 11:2, 4, 15, 12:2-3, 9, 18, 22, 27, 13:2, 17, 14:3, 13, 15:2, 16:2, 17:2, 20:3-4, 27, 46, 21:7, 11, 14, 17, 19, 24, 22:18, 24, 23:2, 36, 24:2, 16, 25, 25:2, 26:2, 27:2, 28:2, 12, 21, 29:2, 18, 30:2, 21, 31:2, 32:2, 18, 33:2, 7, 10, 12, 24, 30, 34:2, 35:2, 36:1, 17, 37:3, 9, 11, 16, 38:2, 14, 39:1, 17, 40:4, 43:7, 10, 18, 44:5.

It is apparent now from this that the Lord in relation to His Divine humanity is called the Son of God, and in relation to the Word the Son of man.

'The spirit of God,' as in Genesis 1:2, signifies the divine mercy of the Lord.

'The spirit of God' denotes good from an interior level, so from the divine. The spirit of God is what proceeds from the divine, so from good itself, because the divine is good itself, and what proceeds from it is truth within which is good. This is what 'the spirit of God' signifies in the Word, because the spirit itself does not proceed, but the truth itself within which is good, the spirit being the instrument which produces it.
