P.423 - §1 Numerous avenues of advancing service are open to cherubim and sanobim leading to an enhancement of status, which may be still further augmented by the embrace of the Divine Minister. There are three great classes of cherubim and sanobim with regard to evolutionary potential:
P.423 - §2 1. Ascension Candidates. These beings are by nature candidates for seraphic status. Cherubim and sanobim of this order are brilliant, though not by inherent endowment equal to the seraphim; but by application and experience it is possible for them to attain full seraphic standing.
P.423 - §3 2. Mid-phase Cherubim. All cherubim and sanobim are not equal in ascension potential, and these are the inherently limited beings of the angelic creations. Most of them will remain cherubim and sanobim, although the more gifted individuals may achieve limited seraphic service.
P.423 - §4 3. Morontia Cherubim. These "fourth creatures" of the angelic orders always retain their quasi-material characteristics. They will continue on as cherubim and sanobim, together with a majority of their mid-phase brethren, pending the completed factualization of the Supreme Being.
Ascension candidates
P.550 - §3 These deserted assistants of the ministering seraphim are often summoned to universe headquarters, where they pass into the intimate embrace of the Universe Mother Spirit and then go forth to the system training spheres as Mansion World Teachers. These teachers often visit the material worlds and function from the lowest mansion worlds on up to the highest of the educational spheres connected with the universe headquarters. Upon their own motion they may return to their former associative work with the ministering seraphim.
Ascension candidates
P.423 - §6 When, as Mansion World Teachers, the once-embraced
cherubim and sanobim have long served on the morontia spheres, from the
lowest to the highest, and when their corps on Salvington is overrecruited,
the Bright and Morning Star summons these faithful servants of the creatures
of time to appear in his presence. The oath of personality transformation
is administered; and thereupon, in groups of seven thousand, these advanced
and senior cherubim and sanobim are re-embraced by the Universe Mother
Spirit. From this second embrace they emerge as full-fledged seraphim.
Henceforth, the full and complete career of a seraphim, with all of its
Paradise possibilities, is open to such reborn cherubim and sanobim. Such
angels may be assigned as guardians of destiny to
P.424 - §0 some mortal being, and if the mortal ward attains survival,
then do they become eligible for advancement to Seraphington and the seven
circles of seraphic attainment, even to Paradise and the Corps of the
Finality.
