In the early morning of religious thought among those Semites it was universally believed that the members of a family or tribe, united by blood-relationship to each other, were also related in the same way to their God. He was their father, the invisible head and source of their community, on whom they had a claim so long as they pleased him. His interest in them was secured by the sacrificial meal which he was invited and believed to share with them. If he had been offended, the sacrificial offering was the means of recovering his favour; and communion with him in those meals and sacrifices was the inheritance of all who claimed the kinship of that clan or tribe. With the clearing of spiritual vision this belief took a new form in the minds of the more thoughtful. The idea of communion remained and the necessity of it to the life of the worshipper was felt even more strongly when the kinship of the God with his subject family was, for the few at least, no longer an affair of physical descent and blood-relationship, but of spiritual origin and attachment. And when faith rose from the tribal god to the idea of the Heaven-Father, the one Creator and King, communion with Him was felt to be in the highest sense a vital necessity. Here is found the religion of Job. A main element of it was communion with Eloah, an ethical kinship with Him, no arbitrary or merely physical relation, but of the spirit. That is to say, Job has at the heart of his creed the truth as to man's origin and nature. The author of the book is a Hebrew; his own faith is that of the people from whom we have the Book of Genesis; but he treats here of man's relation to God from the ethnic side, such as may be taken now by a reasoner treating of spiritual evolution.
