By means of the Literal Sense of the Word Man has Conjunction with the Lord and Consociation with the Angels
The reason why there is conjunction with the Lord by means of the Word is, that the Word treats of Him alone; and therefore the Lord is the all and all of it, and is called the Word, as has been shown in the DOCTRINE CONCERNING THE LORD. The conjunction is in the literal sense because in this sense the Word is in its fullness, in its holiness, and in its power, as was shown above. The conjunction is not apparent to man, but exists in his affection for truth, and in his perception of it, and thus in the love and faith of Divine truth in Him.
The reason why there is consociation with angels by means of the literal sense is, that the spiritual and celestial senses are within this sense, and the angels are in those senses,—the angels of the spiritual kingdom in the spiritual sense of the Word, and the angels of the celestial kingdom in its celestial sense. Those senses are evolved from the natural sense of the Word, which is the literal sense, when a true man is in this sense. The evolution is instantaneous; and therefore the consociation also.
That the spiritual angels are in the spiritual sense of the Word, and the celestial angels in its celestial sense, has been shown me by much experience. It has been granted me to perceive that when I read the Word in its literal sense communication took place with the heavens,—now with one society of them, now with another; and that the things which I understood according to the natural sense, the spiritual angels understood according to the spiritual sense, and the celestial angels according to the celestial sense, and this in an instant. As this communication has been perceived by me some thousands of times, there remains with me no doubt about it. There are also spirits that are beneath the heavens, who abuse this communication; for they read aloud some passages out of the literal sense of the Word, and immediately observe and mark the society with which communication takes place. This too I have often seen and heard. From these circumstances it is given me to know, by living experience, that the Word, as to its literal sense, is the Divine medium of conjunction with the Lord and with heaven. (SS n. 62-64)
I have been informed from heaven that the most ancient people had immediate revelation, since their interiors were turned to heaven; and that thence there was at that time a conjunction of the Lord with the human race. But that after their times there was not such immediate revelation, but mediate by correspondences; for all their Divine worship consisted of correspondences; and therefore the churches of that time were called representative churches. For they then knew what correspondence and what representation was, and that all things that exist on earth correspond to spiritual things which are in heaven and in the church; or what is the same, represented them. The natural things therefore which constituted the externals of their worship, served them as mediums for thinking spiritually, thus with the angels. After the knowledge of correspondences and representations was lost then the Word was written, in which all the words and the meanings of the words are correspondences; they thus contain a spiritual or internal sense, in which the angels are. When therefore a man reads the Word, and understands it according to the literal or external sense, the angels understand it according to the internal or spiritual sense; for all the thought of angels is spiritual, and the thought of man is natural. These thoughts indeed appear diverse; but still they are one, because they correspond. Hence it is that after man removed himself from heaven, and broke the bond, a medium of conjunction of heaven with man by the Word was provided by the Lord. (HH n. 306)
