52. That marriages in the heavens are without prolification, in place whereof is spiritual prolification which is the prolification of love and wisdom, is because, with those who are in the spiritual world, the third thing, which is the natural, is lacking. This is the containant of spiritual things, and without their containant, spiritual things are not set as are those which are procreated in the natural world. Regarded in themselves, spiritual things relate to love and wisdom. It is these, therefore, that are born of their marriages. It is said that they are born, because conjugial love perfects an angel, so uniting him with his consort that he becomes more and more a man; for, as said above [no. 50], two partners in heaven are not two but one angel. Therefore, by conjugial unition they fill themselves with the human, which consists in willing to become wise, and in loving that which pertains to wisdom.
