6027. 'And he sent Judah before him to Joseph' means a communication of the good of the Church with the internal celestial. This is clear from the representation of 'Judah' as the good of the Church, dealt with in 5583, 5603, 5782, 5794, 5837; and from the representation of' Joseph' as the internal celestial, dealt with in 5869, 5877. And 'sending before him', it is self-evident, means communicating. The reason why Judah and not anyone else was sent was so that a direct communication of good with good might be denoted, that is, a direct communication of external good, which 'Judah' represents, with internal good, which 'Joseph' represents. For good that is the good of love to the Lord and charity towards the neighbour flows in from Him by way of the internal into the external, the amount of good in the external determining how much is received there. But if merely the truth of faith and no good is present in a person's external, the inflow of good from the Lord by way of the internal cannot be received in the external. For no direct communication with truth can exist there, only an indirect one through good. This is why Judah and not anyone else was sent from Jacob to Joseph.

1394. The perception which angels and spirits have is such that any one of them can know in an instant the nature of the love and faith in another Hence it is that according to their similarity with one another they are joined together into communities, and according to their dissimilarity they are withheld from such associations. And this is so completely the case that not even the smallest difference fails to draw them together or to set them apart. Consequently the communities in heaven are so distinct and separate from one another that it is impossible to envisage anything more distinct, such distinctness being determined by all the differences of love to and faith in the Lord, which are countless. This is how the heavenly form is produced, the nature of which is such that it presents itself as one human being. And this form is constantly being perfected.
