2803. That the Divine Truth is the “son,” and the Divine Good the “father,” is evident from the signification of a “son,” as being truth (see n. 489, 491, 533, 1147, 2633); and of a “father,” as being good; and also from the conception and birth of truth, which is from good. Truth cannot be and come forth [existere] from any other source than good, as has been shown many times. That the “son” here is the Divine Truth, and the “father” the Divine Good, is because the union of the Divine Essence with the Human, and of the Human Essence with the Divine, is the Divine marriage of Good with Truth, and of Truth with Good, from which comes the heavenly marriage; for in Jehovah or the Lord there is nothing but what is infinite; and because infinite, it cannot be apprehended by any idea, except that it is the being and the coming forth [esse et existere] of all good and truth, or is Good itself and Truth itself. Good itself is the “Father,” and Truth itself is the “Son.” But because as before said there is a Divine marriage of Good and Truth, and of Truth and Good, the Father is in the Son, and the Son is in the Father, as the Lord Himself teaches in John:

Jesus saith unto Philip, Believest thou not that I am in the Father and the Father in Me ? Believe Me that I am in the Father and the Father in me (John 14:10-11).

And again in the same Evangelist:

Jesus said to the Jews, Though ye believe not Me, believe the works; that ye may know and believe that the Father is in Me, and I in the Father (John 10:36, 38).

And again:

I pray for them; for all Mine are Thine, and Thine are Mine; and that they all may be one, as Thou Father art in Me, and I in Thee (John 17:9-10, 21).

And again:

Now is the Son of man glorified, and God is glorified in Him; if God be glorified in Him, God shall also glorify Him in Himself. Father, glorify Thy Son, that Thy Son also may glorify Thee (John 13:31-32; 17:1).

[2] From this may be seen the nature of the union of the Divine and the Human in the Lord; namely, that it is mutual and alternate, or reciprocal; which union is that which is called the Divine Marriage, from which descends the heavenly marriage, which is the Lord’s kingdom itself in the heavens—thus spoken of in John:

In that day ye shall know that I am in My Father, and ye in Me, and I in you (John 14:20).

And again:

I pray for them, that they all may be one, as Thou Father art in Me and I in Thee, that they also may be one in us, I in them and Thou in Me; that the love wherewith Thou hast loved Me may be in them, and I in them (John 17:21-23, 26).

That this heavenly marriage is that of good and truth, and of truth and good, may be seen above (n. 2508, 2618, 2728, 2729 and following numbers).

[3] And because the Divine Good cannot be and come forth without the Divine Truth, nor the Divine Truth without the Divine Good, but the one in the other mutually and reciprocally, it is therefore manifest that the Divine Marriage was from eternity; that is, the Son in the Father, and the Father in the Son, as the Lord Himself teaches in John:

And now O Father, glorify Thou Me with Thyself, with the glory which I had with Thee before the world was (John 17:5, 24).

But the Divine Human which was born from eternity was also born in time; and what was born in time, and glorified, is the same. Hence it is that the Lord so often said that He was going to the Father who sent Him; that is, that He was returning to the Father. And in John:

In the beginning was the Word (the “Word” is the Divine Truth itself), and the Word was with God, and the Word was God; the same was in the beginning with God. All things were made by Him, and without Him was not anything made that was made. And the Word was made flesh, and dwelt among us, and we saw His glory, the glory as of the Only-begotten of the Father, full of grace and truth (John 1:1-3, 14; see also John 3:13; 6:62).

32. Unto God and his Father. That this signifies Divine truth and Divine good, is evident from this, that God denotes Divine truth and Jehovah Divine good, and that therefore, in the Word, the Lord is called God where Divine truth is treated of, and Jehovah, where Divine good is (see n. 2586, 2769, 2807, 2822, 3921, 4287, 4402, 7010, 9167.) But here, instead of Jehovah, the word Father is used, because the Father of the Lord was Jehovah, and by Father is meant the same as by Jehovah. By both, God and Father, the Lord alone is meant, the Father being in Him as the soul is in the body (as may be seen above, n. 10 and 26); for He was conceived of Jehovah; and the soul of every one is from him of whom he is conceived. Therefore, when the Lord made mention of the Father, He meant His Divine in Himself; this is why He said, that, the Father was in Him and He in the Father (John 10:38; 14:10, 11); that the Father and He were one (John 10:30); that He was not alone, but He and the Father (John 16:32). (That the Lord called the Divine of Jehovah, which was in Himself from conception and which was the Being (Esse) of His life in His Human, the Father, and the Divine truth which is from Divine good, the Son, see n. 2803, 3704, 7199, 8328, 8897; that the Son of man is Divine truth, and the Father Divine good, see n. 1729, 1733, 2159, 2628, 2803, 2813, 3255, 3704, 7499, 8897, 9807. See also the citations from Arcana Coelestia, in The Doctrine of the New Jerusalem, concerning the union of the Divine, which is called Jehovah the Father, with the Divine Human of the Lord, n. 304.)
