3365. 'And Isaac went to Abimelech the king of the Philistines, to Gerar' means matters of doctrine concerning faith. This is clear from the representation of 'Isaac' as the Lord as regards the Divine Rational, dealt with in 1893, 2066, 2072, 2083, 2630 - 'Isaac' being the Lord's Divine Rational as regards Divine Good, 3012, 3194, 3210, and also as regards Divine Truth, which is represented by Isaac's marriage to Rebekah, 3012, 3013, 3077, so that 'Isaac' here represents the Lord as regards the Divine Truth joined to the Divine Good of the Rational, since Isaac was accompanied by Rebekah, and she was called his sister; from the representation of 'Abimelech' as the doctrine of faith which has regard to rational concepts, 2504, 2509, 2510, 2533; from the meaning of 'the king of the Philistines' as matters of doctrine - 'the king' in the internal sense being truth that is the truth of doctrine, see 1672, 2015, 2069, and 'the Philistines' the knowledge of cognitions, which are also matters of doctrine, 1197, 1198; and from the meaning of 'Gerar' as faith, 1209, 2504. From these meanings one may see what 'Isaac went to Abimelech the king of the Philistines, to Gerar' means, namely that the Lord is the source of the doctrine of faith which has regard to rational concepts, or what amounts to the same, to matters of doctrine concerning faith.

[2] The expression 'matters of doctrine' is used to describe all those things that constitute doctrine, and insofar as that doctrine is able to be received and to be acknowledged in heaven by angels and on earth by men it is said to have regard to rational concepts. Actually it is the rational that receives and acknowledges them; but the rational is such that it cannot possibly comprehend Divine things, for it is finite, and what is finite cannot comprehend anything of what is Infinite. For this reason Divine truths from the Lord present themselves before the rational by means of appearances. This is why matters of doctrine are no more than the appearances of Divine truth, that is, no more than celestial and spiritual vessels that hold what is Divine within them. And because they hold the Divine, that is, the Lord, within them, they therefore stir a person's affection, and thereby the Lord is joined to angels and to men.

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.
