102. All spiritual creations arising in consequence of the heat and light of their sun are, viewed in themselves, likewise one, but viewed as emanations from the affections of angels, they are not one, as will be seen in subsequent discussions. When heat and light are united in heaven, the climate to angels is like that in springtime. But when they are not united, the climate is either like that in summer, or like that in winter, though not like winter in the colder zones, but like winter in the warmer zones. For the reception of love and wisdom in equal measure is the essence of what it is to be an angel, and an angel is an angel therefore according to the union of love and wisdom in him. It is the same with a person in the church, if the love and wisdom in him, or charity and faith, are united.
