Creative Spirit constitute the permanent population of the constellation headquarters worlds. They are nonreproducing beings existing on a plane of life about halfway between the semimaterial status of the Material Sons domiciled on the system headquarters and the more definitely spiritual plane of the Spirit-fused mortals and the susatia of Salvington; but the univitatia are not morontia beings. They accomplish for ascending mortals during the traversal of the constellation spheres what the Havona natives contribute to the pilgrim spirits passing through the central creation.
The Material Sons of God. When a creative liaison between the Creator Son and the universe representative of the Infinite Spirit, the Universe Mother Spirit, has completed its cycle, when no more offspring of the combined nature are forthcoming, then does the Creator Son personalize in dual form his last concept of being, thus finally confirming his own and original dual origin. In and of himself he then creates the beautiful and superb Sons and Daughters of the material order of universe sonship. This is the origin of the original Adam and Eve of each local system of Nebadon. They are a reproducing order of sonship, being created male and female. Their progeny function as the relatively permanent citizens of a system capital, though some are commissioned as Planetary Adams.
On a planetary mission the Material Son and Daughter are commissioned to found the Adamic race of that world, a race designed eventually to amalgamate with the mortal inhabitants of that sphere. Planetary Adams are both descending and ascending Sons, but we ordinarily class them as ascending.
The Midway Creatures. In the early days of most inhabited worlds, certain superhuman but materialized beings are of assignment, but they usually retire upon the arrival of the Planetary Adams. The transactions of such beings and the efforts of the Material Sons to improve the evolutionary races often result in the appearance of a limited number of creatures who are difficult to classify. These unique beings are often midway between the Material Sons and the evolutionary creatures; hence their designation, midway creatures. In a comparative sense these midwayers are the permanent citizens of the evolutionary worlds. From the early days of the arrival of a Planetary Prince to the far-distant time of the settling of the planet in light and life, they are the only group of intelligent beings to remain continuously on the sphere. On Urantia the midway ministers are in reality the actual custodians of the planet; they are, practically speaking, the citizens of Urantia. Mortals are indeed the physical and material inhabitants of an evolutionary world, but you are all so short-lived; you tarry on your nativity planet such a short time. You are born, live, die, and pass on to other worlds of evolutionary progression. Even the superhuman beings who serve on the planets as celestial ministers are of transient assignment; few of them are long attached to a given sphere. The midway creatures, however, provide continuity of planetary administration in the face of ever-changing celestial ministries and constantly shifting mortal inhabitants. Throughout all of this never-ceasing changing and shifting, the midway creatures remain on the planet uninterruptedly carrying on their work.
In like manner, all divisions of the administrative organization of the local universes and superuniverses have their more or less permanent populations, inhabitants of citizenship status. As Urantia has its midwayers, Jerusem, your system capital, has the Material Sons and Daughters; Edentia, your constella-
