To climb to the supernal heights of finaliter sonship with God is a masterly achievement for an angel, an accomplishment far transcending your attainment of eternal survival through the plan of the Eternal Son and the ever-present help of the indwelling Adjuster; but the guardian seraphim, and occasionally others, do actually effect such ascensions. 
Bestowal attendants are completion seraphim; they have all traversed the circles of Seraphington and have attained the Seraphic Corps of Completion. Such seraphim have all achieved Paradise and the personal embrace of the Second Source and Center, the Eternal Son. 
Many of the Seraphington graduates, members of the Seraphic Corps of Completion who are associated with these seraphim, engage in teaching in the Salvington schools concerned with the preparation of the creatures of Nebadon for the next universe age.
