Revealed truth was threatened with extinction during the millenniums which followed the miscarriage of the Adamic mission on Urantia. Though making progress intellectually, the human races were slowly losing ground spiritually. About 3000 B.C. the concept of God had grown very hazy in the minds of men.
The twelve Melchizedek receivers knew of Michael’s impending bestowal on their planet, but they did not know how soon it would occur; therefore they convened in solemn council and petitioned the Most Highs of Edentia that some provision be made for maintaining the light of truth on Urantia. This plea was dismissed with the mandate that “the conduct of affairs on 606 of Satania is fully in the hands of the Melchizedek custodians.” The receivers then appealed to the Father Melchizedek for help but only received word that they should continue to uphold truth in the manner of their own election “until the arrival of a bestowal Son,” who “would rescue the planetary titles from forfeiture and uncertainty.”
And it was in consequence of having been thrown so completely on their own resources that Machiventa Melchizedek, one of the twelve planetary receivers, volunteered to do that which had been done only six times in all the history of Nebadon: to personalize on earth as a temporary man of the realm, to bestow himself as an emergency Son of world ministry. Permission was granted for this adventure by the Salvington authorities, and the actual incarnation of Machiventa Melchizedek was consummated near what was to become the city of Salem, in Palestine. The entire transaction of the materialization of this Melchizedek Son was completed by the planetary receivers with the co-operation of the Life Carriers, certain of the Master Physical Controllers, and other celestial personalities resident on Urantia.
