The Lord's Omnipresence and Omniscience

All the angels of heaven and all the men on the earth who constitute the church are as one man, and the Lord is the life of that man.

Selection from
Apocalypse Explained
According to the spiritual sense
 in which the arcana there predicted
but heretofore concealed are revealed.

Emanuel Swedenborg

(3) This you will see confirmed in the work on Heaven and Hell, in the following articles: The whole Heaven in the complex has relation to one Man (n. 59-67); Each Society in the heavens has relation to one Man (n. 68-72); Consequently each Angel is in a perfect Human Form (n. 73-77); Heaven as a whole and in part has relation to Man, and this is from the Lord's Divine Human (n. 78-86); There is a correspondence of all things of Heaven with all things of Man (n. 87-102; The same may be said of the Lord's church on the earth (n. 57).

That heaven is like one man I have been taught by experience and am taught by reason.

Experience: It has been granted me to behold a society consisting of thousands of angels as one man of a medium stature, and societies consisting of fewer angels in like form. This is seen, however, not by the angels in that society, but by angels outside of that society at a distance, and at the time when a society is to be purified of those who are foreign to it. When this is done all who constitute the life of that society are within that man, while those who do not are outside of him; and these are removed, but the former remain. It is the same with the whole heaven in the presence of the Lord. For this reason and no other every angel and spirit is a man, in a form like that which a man on earth has.

I have not seen but I have heard that the church on earth also before the Lord is like one man; and that it is also divided into societies, and that each society is a man; furthermore, that all who are within that man are within heaven, while those who are outside of him are in hell; and the reason has been stated, namely, that every man of the church is also an angel of heaven, for he becomes an angel after death. Moreover, not only does the church on earth together with the angels constitute the interiors of that man, the church constitutes also the exteriors, which are called the cartilaginous and bony parts; this the church constitutes, because the men of the earth are provided with a body in which the lowest spiritual is clothed with the natural. This is what constitutes the conjunction of heaven with the church and of the church with heaven.

From reason: Heaven and the church are a man, in the greatest, the lesser, and the least sum or complex, for the sole reason that God is Man, and consequently the Divine proceeding, which is the Divine from Him, is the same in every least and greatest respect, which is man. For it has been said above that the Divine is not in space and extension, but causes spaces and extensions to exist in the ultimates of His creation, in the heavens apparently, in the world actually. Nevertheless spaces and extensions are not spaces and extensions before God,* for He is in His Divine everywhere. This is clearly manifest from this, that the whole angelic heaven with the church is as one man before God; and so is a society consisting of thousands of angels, although their habitations appear extended through much space. The same is evident also from this, that the whole heaven, also an entire society in heaven, can appear at the good pleasure of the Lord, as a man, great or small, as a giant or as an infant. But it is not the angels that so appear, but the Divine in them; for the angels are only recipients of the Divine from the Lord, and it is the Divine in them that constitutes what is angelic in them and thus heaven. As angels are only recipients, and the Divine in them constitutes what is angelic and heaven, it is clear that the Lord is the life of that man, that is, of heaven and the church.
