All the communities in the heavens are differentiated according to their forms of service because they are differentiated according to their virtues, as has been noted above (Sections 41–45). Their virtues are virtues in action or acts of thoughtfulness, which are services. There are some communities whose tasks are to take care of babies; there are other communities whose tasks are to teach and lead children while they are growing up; there are other communities that look after young boys and girls who are well disposed because of the way they were raised in this world and have come [straight] to heaven, where they are taught and raised in much the same way. There are some that teach simple people from the Christian world and lead them on the way to heaven, and there are some that do the same for various non-Christian peoples. There are some that protect new spirits, just arrived from the world, from the attacks of evil spirits; and there are some who attend to people in the lower earth. Then there are some who attend to people in the hells and control them so that they do not torture each other beyond set limits. There are also some who tend to people who are being awakened from their death.
Broadly speaking, angels of all communities are assigned to us to protect us, to lead us away from evil feelings and the evil thoughts that these cause and to instill good feelings to the extent that we are freely open to them. These serve to control our deeds or works by removing our evil intentions to the extent that this can be done. When angels are with us they seem to dwell in our affections, near us to the extent that we are engaged in something good because of truth, and distant to the extent that our life is removed from such engagement.
However, all these tasks are things the Lord does by means of angels, since angels do them not on their own but from the Lord. This is why in the deeper meaning of the Word “angels” does not mean angels but something of the Lord; and this is why angels are called gods in the Word.
These are general categories of angels’ activities, but each individual has her or his own specific contribution to make. This is because every general service is made up of countless elements that are called mediate or subservient or supporting services. All of these are arranged and ranked according to the divine design, and taken together they make up and complete an overarching function that is the common good.
