Arcana Coelestia # 5515
5515. 'The sons of our father' means having the same origin. This is clear from the meaning of 'the sons' as truths, dealt with in 489, 491, 533, 1147, 2623, 3373, and from the meaning of 'father' as good, dealt with in 2803, 3703, 3704. Consequently 'the sons of our father' means truths springing from good, thus truths having the same origin; they are all truths originating in one and the same good.
Sorrow
The woman condemned to 'bring forth sons in sorrow' denotes the anxieties and combats in the production of truths.
