They say that thousands of human concepts and statements have been used to facilitate comprehension and communication. The authors also tell us they are rigorously restricted, and are not allowed to anticipate developments in the future. The science and cosmology of the book, we are told, are not revelatory, and will soon be in need of revision. Knowledge must be achieved by evolutionary discovery, but it is integrated and given spiritual value orientation by revelation. This saves much time in eliminating the errors and distortions of evolution.
Revelation is never too far removed from the thought process of the age in which it is given.
It is rooted solidly in evolutionary foundations. It can only be validated by experience, and is never complete until we meet the Universal Father on Paradise. The Christian conception of Deity is centered in the doctrine of the Trinity. We have had problems understanding how three persons can exist and function as a monotheistic entity. The Urantia Book clarifies the concept by describing the unique functions of each person of the Trinity as well as affirming their absolute unity.
