P.245 - §1 Mighty Messengers belong to the ascendant group of the Trinitized Sons. They are a class of perfected mortals who have been rebellion tested or otherwise equally proved as to their personal loyalty; all have passed through some definite test of universe allegiance. At some time in their Paradise ascent they stood firm and loyal in the face of the disloyalty of their superiors, and some did actively and loyally function in the places of such unfaithful leaders.
P.245 - §5 Mighty Messengers are embraced by the Paradise Trinity in classes of seven hundred thousand, one hundred thousand for assignment to each superuniverse. Almost one trillion Mighty Messengers are commissioned on Uversa, and there is every reason to believe that the number serving in each of the seven superuniverses is exactly the same.
