Firstborn, in a supreme sense, represents the Lord as to divine celestial love, and also peope who were of the celestial church. The sanctification of the firstborn, as in Exodus 13, signifies faith in the Lord. The firstborn, in the spiritual sense of the Word, is good, for with infants the good of innocence is first infused by the Lord, by virtue of which man first becomes a man. Since good is of love, and man does not reflect upon his own love, but only upon the thoughts of his memory, and since good has not at first a quality, but acquires one when it is formed in truths, and without a quality nothing is perceived, hence it was unknown that good was the primary principle, or firstborn. Good is first conceived from the Lord in man, and is produced by truths, in which good is manifested, in its own form and effigy. Firstborn, as in Psalm 89:28, signifies the Lord's humanity.

Father in the Word means what is most interior, and in those things that are following the Lord's order, it means what is good. In the highest sense Father means the Lord Himself, the creator. In the generation of natural children it is the father who provides the soul or the most interior receptacle of life, and an internal heredity, and the mother who provides all of the substance that the soul uses to form its body, plus an external heredity. In this process the soul comes from the Lord through the father, and not from the father, since all life is from the Lord. The wise person calls the Lord his father and the church his mother because his interior loves come from the Lord, but are given form and actuality through the truths taught by the church. Those things thus brought forth are a person's spiritual "children". In the New Testament, when speaking of Jesus and the Father, what is meant is the outward manifestation with the divine itself as the soul inside. Because Jesus was born from a natural mother, He had a natural body and a natural Jewish heredity. Throughout his life as He was tempted by the hells, He slowly put off all he had from His mother and replaced it with what He had from Himself inside, the Father. In doing this he made himself one with the Father that was His inmost so He could truly say, "I and my Father are one".
