With the passing of a decade, Melchizedek organized his schools at Salem, patterning them on the olden system which had been developed by the early Sethite priests. Even the idea of a tithing system, which as introduced by his later convert Abraham, was also derived from the lingering traditions of the methods of the ancient Sethites.
Melchizedek taught the concept of one God, a universal Deity. The symbol of the three concentric circles, which Melchizedek adopted as the insignia of his bestowal, a majority of the people interpreted as standing for the three kingdoms of men, angels, and God. And they were allowed to continue in that belief; very few of his followers ever knew that these three circles were emblematic of the infinity, eternity, and universality of divine maintenance and direction; even Abraham rather regarded this symbol as standing for the three Most Highs functioning as one.
To the rank and file of his followers he made no effort to present teaching beyond the fact of the rulership of the Most Highs — Gods of Urantia. But to some, Melchizedek taught advanced truth, embracing conduct and organization above such Gods of Urantia.
The members of the family of Katro, with whom Melchizedek lived for more than thirty years, knew many of these higher truths and long perpetuated them in their family, even to the days of their illustrious descendant Moses, who thus had a compelling tradition of the days of Melchizedek handed down to him on this, his father’s side, as well as through other sources of his mother’s side.
Melchizedek taught his followers all they had capacity to receive and assimilate. Even many modern religious ideas about heaven and earth, of man, God, and angels, are not far removed from these teachings of Melchizedek. But this great teacher subordinated everything to the doctrine of one God, a universe Deity, a heavenly Creator, a divine Father.
Melchizedek taught that at some future time another Son of God (Michael, bestowed as Jesus of Nazareth), would come in the flesh as he had come, but that he would be born of a woman; and that is why numerous later teachers held that Jesus was a priest, or minister, “forever after the order of Melchizedek.”
And thus did Melchizedek prepare the way and set the monotheistic stage of world tendency for the bestowal of an actual Paradise Son of the one God, Michael, whom he so vividly portrayed as the Father of all, and whom he represented to Abraham as a God who would accept man on the simple terms of personal faith. And Michael, when he appeared on earth, confirmed all that Melchizedek had taught concerning the Paradise Father.
