The Divine needs to connect with what's been created, especially to what is human. Since the Divine Itself is, in its essence, beyond human comprehension, we can see and know it from its visible forms which are the Word, Jesus Christ, the created universe, and even the the human mind and body. These and many other things express the Divine Human.

To understand this further, imagine that you are completely paralyzed, to the point that you can’t make a sound or even move your eyes or the muscles of your face. Someone you love walks up to you. Inside, you feel a surge of affection. But how can you show it? You can’t say it, can’t smile, can’t even form an expression in your eyes. It can’t be done; you have no communication at all.

To be expressed, then, love needs a vessel, something capable of communication. That vessel is what Swedenborg calls the “human.”

For us, in the physical world, that “human” is in the form of our physical bodies. Through them we can smile, laugh, speak, hug, kiss, write - and can also strike out, shout in anger and criticize. Our bodies are the vessels that let us share what’s inside with the people around us. Through our bodies we also see, hear and feel the things inside others. They are the mode through which we interact.

But imagine if you could read minds, and could allow your mind to be read by others. You would no longer need your body as a vessel, but the things you shared would still be human; they would be human thoughts, human feelings, human ideas, still distinctly your own and reflective of the kind of person you are. You’d still have a “human,” but it would be your mind instead of your body.

That can give us some idea of what the Lord’s “human” is: it is the vessel through which we can receive His love and His guidance. It’s not something physical, like our human bodies, but is spiritual, as our minds are spiritual. And it puts His love into feelings, images and ideas, just as our minds do.

Put that way, it’s easy to see that the Lord’s humanity has always been, and was indeed an agent of creation: in creating the universe, the Lord used his human to give form to His love, forms that would be separate from Him, forms that He could love. It’s also easy to see that His humanity will always be: He is love itself, and that love will always need a vessel.

The Lord’s “human” also fills another great need. We are finite; the Lord is infinite. We live in a world of dead physical matter; the Lord is life itself. We are born into selfish loves; the Lord loves us infinitely. We live in time and space and can only think in terms of time and space; the Lord is outside of time and space, uncontained and uncontainable. For these and many other reasons the Lord, in His essence, is inconceivable to us; we have no mental tools to form an idea of the infinite. We can, however, think of the Lord as a human, and can thus worship him in the form of His divine human. By relating his love to us, his humanity makes it possible for us to relate to Him.

That leaves one great question: what about Jesus? He was human, but also kind of God, too. How does that relate to the idea of the divine human?

The answer lies in how we receive what the Lord gives us, and how that reception has changed over the millennia.

The Lord’s love is conveyed to us through the divine human in the form of what Swedenborg calls “divine truth,” which is essentially the Lord’s thoughts, His ideas. These thoughts are, of course, all about love, and are filled to overflowing with His love.

The earliest people, those of what Swedenborg calls the “Most Ancient Church,” could receive those thoughts directly, and accept the love in them directly. From this they were pure and innocent to a degree we can barely imagine, with wisdom and insight that sprang from the love they shared.

As people drew away from the Lord, though, their ability to accept the love contained within the divine truth began to degrade. In what Swedenborg calls the “Ancient Church” people received it in the form of love of one another, and accessed it through powerfully symbolic stories and the symbolism of nature. Finally, with the Children of Israel, the love and the truth were almost completely separated, with the Lord’s ideas contained within ritual, but His inspiration to be good operating in a disconnected way. Ultimately those people grew so evil that the desire for good was in danger of being choked off forever.

So the Lord rendered his “human” into physical flesh, born as a child to the virgin Mary. As always, that human was a vessel for the Lord’s love, but it was a vessel that could share divine truth in a tangible way. Swedenborg’s works say that Jesus spent his life stripping away His mortal aspects by battling temptations, and was a form of divine truth when He began His ministry. During His ministry he stripped away his mortal loves, until in the final temptation on the cross he was fully reunited with the divine love that was His soul. In His ministry, then, he shared His deepest ideas, and in His death He shared the love that formed and filled those ideas. It was enough to save humankind forever.

In doing this the Lord also changed His relationship with us. He gave us deeper truths about how to be loving, and taught us that love is more important than ritual. He also opened for us the idea that the Bible is full of deeper and richer meanings: that it is itself a form of divine truth. With these tools we now have the ability to use the Lord’s ideas as a key to accept His love. By knowing what’s right, knowing what the Lord teaches, we can compel ourselves to act in loving ways even if we don’t feel the love, and the Lord will use that to reform us so that we come to actually love what is good.

So the Divine Human is still a vessel for the Lord’s love, as it has always been. It’s a vessel that has adapted according to our needs and the paths the Lord can use to draw us toward heaven.

2715. Two arcana exist here, the first being that, compared with the good of the celestial man, that of the spiritual man is obscure, the second that this obscurity is brightened by light from the Lord's Divine Human. As regards the first of these - that the good residing with the spiritual man is obscure compared with the celestial man's - this may be seen from what has been stated above in 2708 about the state of the spiritual man in comparison with that of the celestial man. From a comparison of the two states the fact of that obscurity is quite evident. With those who are celestial good itself exists implanted in the will part of their mind, and from there light enters the understanding part. But with those who are spiritual the whole of the will part is corrupted, so that they have no good at all from there, and therefore the Lord implants good in the understanding part of their mind, see 863, 875, 895, 927, 928, 1023, 1043, 1044, 2124, 2256. The will part is, in the main, the part of man's mind that possesses life, whereas the understanding part receives life from the will. Since therefore the will part in the case of the spiritual man is so corrupted as to be nothing but evil, and yet evil is flowing in from there unceasingly and constantly into the understanding part, that is, into his thought, it is clear that the good there is obscure compared with the celestial man's good.

[2] As a consequence those who are spiritual do not have love to the Lord, as those who are celestial do; nor therefore does that humility exist with them which is essential in all worship and by means of which good can flow in from the Lord; for a heart that is haughty is not at all receptive, only one that is humble. Nor do those who are spiritual have love towards the neighbour, as those who are celestial do, because self-love and love of the world are constantly flowing in from the will part of their mind, bringing obscurity into the good that goes with that love towards the neighbour. This may also become clear to one who reflects from the fact that when he helps another he does so for worldly reasons; thus though he may not consciously have it in mind he is nevertheless thinking about what he will get in return either from those he helps or in the next life from the Lord, which being so his good is still defiled with merit-seeking. It may also become clear to him from the fact that when he has done anything good and is able to speak about it to others and so set himself up above others, he is in his element. But those who are celestial love the neighbour more than they love themselves, and do not ever think about repayment or in any way set themselves up above others.

[3] The good residing with those who are spiritual is in addition made obscure by persuasive beliefs that are the product of various assumptions, which likewise have their origin in self-love and love of the world. For the nature of their persuasive beliefs even in matters of faith, see 2682, 2689 (end). This too is a product of the influx of evil from the will part of their mind.

[4] It may in addition become clear that the good residing with the spiritual man is obscure compared with the celestial man's, from the fact that he does not know what truth is, as those who are celestial do, from any perception. Instead he knows what truth is from what he has learned from parents and teachers, and also from the doctrine into which he was born. And when he adds to this anything from himself and from his own thinking, it is for the most part the senses and the illusions of the senses, also the rational and the appearances present within the rational, that predominate, and these make it barely possible for him to acknowledge any pure truth like that acknowledged by those who are celestial. But in spite of this, within things that are seemingly true the Lord implants good, even though these truths are mere illusions or else appearances of truth. But this good is made obscure by such truths, for it derives its specific nature from the truths to which it is joined. It is like the light of the sun falling upon objects. The nature of the objects receiving the light causes the light to be seen within those objects in the form of colours, which are beautiful if the nature of the recipient form and the manner of its receiving are fitting and correspondent, hideous if the nature of the recipient form and the manner of its receiving are not fitting and so not correspondent. In the same way good itself acquires a specific nature from the truth [to which it is joined].

[5] The same arcanum is also evident from the fact that the spiritual man does not know what evil is. He scarcely believes that any other evils exist than actions contrary to the Ten Commandments. Of evils present in affection and thought, which are countless, he has no knowledge nor does he reflect on them or call them evils. All delights whatever that go with evil desires and pleasures he does not regard as other than good; and the actual delights that are part of self-love he both pursues, approves of, and excuses, without knowing that such things have an effect on his spirit and that he becomes altogether such in the next life.

[6] From this it is in a similar way clear that although the whole of the Word deals with scarcely any other matter than the good which goes with love to the Lord and love towards the neighbour, the spiritual man does not know that that good is the sum and substance of faith, nor even what the essential nature of love and charity is. It is also clear that though something which is a matter of faith may be known to him - faith being considered by him to be essential in itself - he nevertheless discusses whether it is true, unless he has been confirmed by much experience of life. Those who are celestial do not discuss the same because they know and have a perception that it is true hence the Lord's statement in Matthew,

Let your words be, Yes, yes; No, no; anything beyond this is from evil. ¹ Matthew 5:37.

For those who are celestial are immersed in the truth itself about which those who are spiritual dispute. Consequently because those who are celestial are immersed in the truth itself, they are able to see from it numberless facets of that truth, and so from light to see so to speak heaven in its entirety. But those who are spiritual, because they dispute whether it is true, cannot - so long as they do so - arrive at the remotest boundary of the light existing with those who are celestial, let alone behold anything from their light.

9303. 'Behold, I send an angel before you' means the Lord's Divine Human. This is clear from the meaning of 'sending', when it refers to the Lord, as going forth, dealt with in 6831, at this point causing to go forth; and from the meaning of 'an angel' as one who goes forth, for the word for 'angel' in the original language means one who has been sent. This is the derivation of the word, and 'one sent' means one going forth, as becomes clear from the places in the Word referred to in 6831. From this it is evident that 'the angel of Jehovah' is used to mean the Lord's Divine Human, for this comes forth from Jehovah as the Father. Jehovah as the Father is the Divine Good of Divine Love, which is Essential Being (Esse), 3704; and He who comes forth from the Father is the Divine Truth emanating from that Divine Good. He is accordingly the Divine Coming-into-Being (Existere) that arises from the Divine Being; and this Coming-into-Being is meant here by 'an angel'. The like occurs in Isaiah,

The angel of His face delivered them; because of His love and His compassion He redeemed them, and took them and carried them all the days of eternity. Isaiah 63:9.

And in Malachi,

Behold, suddenly there will come to His temple the Lord whom you are seeking, and the angel of the covenant in whom you delight. Malachi 3:1-2.

'To the Lord's temple' means to His Human. The Lord Himself teaches that this is His temple, in Matthew 26:61, and in John 2:19, 21-22.

[2] The Church declares that from the three who are named Father, Son, and Holy Spirit exists a Divine Unity, also called One God, and that the Son proceeds from the Father, and the Holy Spirit from the Father through the Son. But what proceeding or going forth means remains unknown. Angels' ideas about this are altogether different from those of people in the Church who have given thought to the matter. The reason for this is that the ideas of people in the Church are based on three, but those of angels on one. And the reason why the ideas of people in the Church are based on three is that they distinguish the Divine [Being] into three separate persons, to each of whom they attribute particular and specific functions. Consequently although they are indeed able to say that God is one, they can conceive only of three made one through mystical union, as they call it. This indeed allows them to conceive of Divine Unity but not of One God, since they have God the Father, God the Son, and God the Holy Spirit in mind. Divine Unity is unity arrived at through agreement and so unanimity; but One God is wholly and completely one.

[3] What kind of idea or way of thinking members of the Church have about one God is perfectly clear in the next life, for each individual person takes his ideas and thoughts with him. In their thinking they envisage three gods, but they dare not to use the word 'gods', only 'God'. Few moreover make one out of three through union; for they think of the Father in one way, of the Son in another, and of the Holy Spirit in yet another. This has shown what kind of belief the Church has regarding the most essential thing of all, namely the Deity Himself. And since the belief and thoughts and the love and affections of all in the next life bring them together or set them apart, those who have been born outside the Church and have believed in one God shy away from those within the Church. They say that those within the Church do not believe in one God but in three gods, and that those who do not believe in one God in human form believe in no God at all, since they think of the whole universe, endless in extent, and so think of the natural order, which they acknowledge in place of God. When members of the Church are asked what they understand by 'proceeding' when they say that the Son proceeds from the Father, and the Holy Spirit from the Father through the Son, they reply that 'proceeding' is a term which has to do with union and is all part of that mystery.

[4] But when their ideas and thoughts about it have been examined, they have proved to be no more than those of a term and nothing of real substance. But angels' ideas about the Godhead, about the Trinity, and about proceeding are altogether different from those of members of the Church, because angels' ideas and thoughts, as stated above, are based on one, whereas those of members of the Church are based on three. Angels think - and what they think they believe - that there is one God and He is the Lord, that His Human is the Deity Himself in outward form, and that the holiness proceeding from Him is the Holy Spirit, thus that though there is a Trinity the Deity is intrinsically One.

[5] An idea concerning the angels in heaven may serve to make this intelligible. An angel there is seen in human form; nevertheless there are three things with him which make one. There is the inward part of him which does not appear before people's eyes, there is the outward part which does appear, and there is the sphere of the life belonging to his affections and thoughts, which flows out far and wide from him, regarding which see 1048, 1053, 1316, 1504-1519, 1695, 2489, 4464, 5179, 6206 (end), 7454, 8063, 8630. These three make one angel. But angels are finite, created beings, whereas the Lord is Infinite and Uncreated; and since no one, not even an angel, can have an idea of the Infinite except from things that are finite, it is permissible to use such an example to shed light on what the Three in One is, on the truth that there is One God, and on the truth that He is the Lord, and no other. See in addition what has been shown already on these matters in the places referred to in 9194, 9199.
