Seraphic tasks may be unremitting, but either of the angelic pair can discharge all ministering responsibilities. Like cherubim, seraphim usually serve in pairs, but unlike their less advanced associates, the seraphim sometimes work singly. In practically all their contacts with human beings they can function as individuals. Both angels are required only for communication and service on the higher circuits of the universes.

Aren’t they all serving spirits, sent out to do service for the sake of those who will inherit salvation?
The cherubim mounted up. This is the living creature that I saw by the river Chebar. When the cherubim went, the wheels went beside them; and when the cherubim lifted up their wings to mount up from the earth, the wheels also didn’t turn from beside them. When they stood, these stood. When they mounted up, these mounted up with them; for the spirit of the living creature was in them.
This is the living creature that I saw under the God of Israel by the river Chebar; and I knew that they were cherubim. Every one had four faces, and every one four wings. The likeness of the hands of a man was under their wings. As for the likeness of their faces, they were the faces which I saw by the river Chebar, their appearances and themselves. They each went straight forward.
