2533. That 'now return the man's wife' means that the spiritual truth of doctrine was by him to be brought back untouched from the rational is clear from the meaning of 'a wife' as spiritual truth, dealt with in 2507, 2510, and from the meaning of 'a man' as doctrine itself. Actually when Abraham who represents the Lord in that state is called 'a man' he means celestial truth, which is the same as doctrine from a celestial origin; for 'man' in the internal sense means the understanding part of the mind, see 158, 265, 749, 915, 1007, 2517. From this it is evident that 'resuming the man's wife' means bringing back the spiritual truth of doctrine untouched. Its being brought back untouched from the rational is meant because 'Abimelech' who was required to return her means doctrine that has regard to rational things, or what amounts to the same, means the rational things comprising doctrine, 2510.

[2] It has been stated above that although the doctrine of faith is in itself Divine and so stands above all human, even angelic, range of understanding, it has nevertheless been expressed in the Word in a rational manner in accordance with man's range of understanding. It is like a parent who is teaching small boys and girls. When teaching them he explains every single thing in accordance with their own mentality, even though he himself thinks from what is more interior or higher. Otherwise he would be teaching without their learning, or it would be like casting seed on bare rock. The same applies also to the angels who in the next life instruct the simple in heart. Although the angels possess celestial and spiritual wisdom they nevertheless do not go above the heads of those they are teaching but use simple ideas to talk to them, yet advance by degrees to higher ideas as the instruction advances. For if they were to speak from angelic wisdom the simple would not grasp anything at all and so would not be led on to the truths and goods of faith. Much the same would happen if in the Word the Lord had not taught in a rational manner in accordance with man's range of understanding. Nevertheless in its internal sense the Word is raised up to angelic understanding. But even so, that highest level of meaning on which the Word exists with angels is infinitely lower than the Divine. This shows what the Word is like in origin, and so what it is in itself, and thus that at every point it embodies more than the whole of heaven is capable of comprehending, even as to one small part, though in the letter it seems so ordinary and so crude.

[3] The fact that the Lord is the Word, because the Word derives from Him and He is in the Word, is clear in John,

In the beginning was the Word, and the Word was with God, and the Word was God. In Him was life, and the life was the light of men. The Word became flesh and dwelt among us, and we beheld His glory, glory as of the Only Begotten from the Father, full of grace and truth. John 1:1, 4, 14.

See also Revelation 19:11, 13, 16. And because the Lord is the Word, He is doctrine also, for no other doctrine exists which is itself Divine.

2508. 'She is my sister' means rational truth. This is clear from the meaning of 'a sister' as rational intellectual truth, dealt with in 1495. That rational truth is meant by 'a sister' cannot be seen by anyone except from the heavenly marriage; for the things that descend from that marriage have links with one another - resembling the ties of blood-relationships and relationships by marriage on earth, concerning which see 685, 917 - and in ways endlessly varying. The heavenly marriage exists solely between Divine Good and Divine Truth. Conceived from that marriage there exist with man the capacities to understand, to be rational, and to have knowledge; for without this conception from the heavenly marriage no one can possibly be endowed with understanding, reason, or knowledge, and cannot consequently be a human being. Insofar therefore as he draws from the heavenly marriage he is human. The heavenly marriage exists within the Lord Himself, so that the Lord is that marriage itself; for He is Divine Good itself and at the same time Divine Truth. The heavenly marriage exists with angels and men insofar as love to the Lord and charity towards the neighbour, and consequently insofar as faith derived from these exist with them, that is, insofar as the Lord's good and the truth derived from this do so. When this is the case with them they are called 'daughters and sons', and in relation to one another 'sisters and brothers', but with differences. The reason rational truth is called 'a sister' is that it is conceived from the influx of Divine Good into the affection for rational truths. The good conceived in this way in the rational is called 'a brother', and the truth 'a sister'. But this will be clearer from the words spoken by Abraham in verse 12 of this chapter, 'And also she is truly my sister, my father's daughter but not my mother's daughter; and she became my wife'.
