20:8.2
The exact number of Teacher Sons in Nebadon I do not know; there are many thousands of them. Many of the heads of departments in the Melchizedek schools belong to this order, while the combined staff of the regularly constituted University of Salvington embraces over one hundred thousand including these Sons. Large numbers are stationed on the various morontia-training worlds, but they are not wholly occupied with the spiritual and intellectual advancement of mortal creatures; they are equally concerned with the instruction of seraphic beings and other natives of the local creations. Many of their assistants are drawn from the ranks of the creature-trinitized beings.
