If, then, one were to explore carefully the whole circuit of the writings of Moses and his successors, one would find it included exhortation and teaching of duty to the God of the Universe, Who is the Creator of all things, and the knowledge and divine teaching relating to the highest secondary Cause, and prohibition of all polytheistic error, (208) and then the memorial of the godly men of old days who began the said religion, and predictions and proclamations of those who would live in after days, as they themselves had lived, through the appearance and presence of God among men, I mean of the secondary Lord and God after the Supreme Father, Who Himself would become the Teacher of the same religion, and be revealed as Saviour (b) of the life of men, through Whom they foretold that the ideals of the ancient godly Hebrews would be handed on to all nations. This was the Gospel that Moses foretold, as well as the sons of the other prophets, who all spake as with one mouth. And this was the reason of the descent of the Holy Spirit to men, to teach men the knowledge of God, and the loftiest theology of the Father and the Son, to train them in every form of true religion, to give a record of those who lived well long ago, and those who afterwards fell away from the religion of their forefathers, and to exhibit the case against them at great length: and then (c) to prophesy the coming of the Saviour and Teacher of the whole race of mankind, and to herald the sharing of the religion of the ancient Hebrews by all nations.
