Most of the inhabited worlds of Nebadon harbor one or more groups of unique beings existing on a life-functioning level about midway between those of the mortals of the realms and of the angelic orders; hence are they called midway creatures. They appear to be an accident of time, but they occur so widespreadly and are so valuable as helpers that we have all long since accepted them as one of the essential orders of our combined planetary ministry.

On Urantia there function two distinct orders of midwayers: the primary or senior corps, who came into being back in the days of Dalamatia, and the secondary or younger group, whose origin dates from the times of Adam.

The primary midwayers have their genesis in a unique interassociation of the material and the spiritual on Urantia. We know of the existence of similar creatures on other worlds and in other systems, but they originated by dissimilar techniques.

It is well always to bear in mind that the successive bestowals of the Sons of God on an evolving planet produce marked changes in the spiritual economy of the realm and sometimes so modify the workings of the interassociation of spiritual and material agencies on a planet as to create situations indeed difficult of understanding. The status of the one hundred corporeal members of Prince Caligastia's staff illustrates just such a unique interassociation: As ascendant morontia citizens of Jerusem they were supermaterial creatures without reproductive prerogatives. As descendant planetary ministers on Urantia they were material sex creatures capable of procreating material offspring (as some of them later did). What we cannot satisfactorily explain is how these one hundred could function in the parental role on a supermaterial level, but that is exactly what happened. A supermaterial (nonsexual) liaison of a male and a female member of the corporeal staff resulted in the appearance of the first-born of the primary midwayers.

It was immediately discovered that a creature of this order, midway between the mortal and angelic levels, would be of great service in carrying on the affairs of the Prince's headquarters, and each couple of the corporeal staff was accordingly granted permission to produce a similar being. This effort resulted in the first group of fifty midway creatures.

After a year of observing the work of this unique group, the Planetary Prince authorized the reproduction of midwayers without restriction. This plan was carried out as long as the power to create continued, and the original corps of 50,000 was accordingly brought into being.
