51:0.1 During the dispensation of a Planetary Prince, primitive man reaches the limit of natural evolutionary development, and this biologic attainment signals the System Sovereign to dispatch to such a world the second order of sonship, the biologic uplifters. These Sons, for there are two of them—the Material Son and Daughter—are usually known on a planet as Adam and Eve. The original Material Son of Satania is Adam, and those who go to the system worlds as biologic uplifters always carry the name of this first and original Son of their unique order.
51:0.2 These Sons are the material gift of the Creator Son to the inhabited worlds. Together with the Planetary Prince, they remain on their planet of assignment throughout the evolutionary course of such a sphere. Such an adventure on a world having a Planetary Prince is not much of a hazard, but on an apostate planet, a realm without a spiritual ruler and deprived of interplanetary communication, such a mission is fraught with grave danger.
51:0.3 Although you cannot hope to know all about the work of these Sons on all the worlds of Satania and other systems, other papers depict more fully the life and experiences of the interesting pair, Adam and Eve, who came from the corps of the biologic uplifters of Jerusem to upstep the Urantia races. While there was a miscarriage of the ideal plans for improving your native races, still, Adam's mission was not in vain; Urantia has profited immeasurably from the gift of Adam and Eve, and among their fellows and in the councils on high their work is not reckoned as a total loss.
