Starting from this general notion of what the prophet sought, we can see, in the next place, that his attention must be mainly concentrated on matters belonging to public worship and ritual. Worship is the direct expression in word and act of man’s attitude to God, and no public religion can maintain a higher level of spirituality than the symbolism which gives it a place in the life of the people. That fact had been abundantly illustrated by the experience of centuries before the Exile. The popular worship had always been a stronghold of false religion in Israel. The high places were the nurseries of all the corruptions against which the prophets had to contend, not simply because of the immoral elements that mingled with their worship, but because the worship itself was regulated by conceptions of the deity which were opposed to the religion of revelation. Now the idea of using ritual as a vehicle of the highest spiritual truth is certainly not peculiar to Ezekiel’s vision. But it is there carried through with a thoroughness which has no parallel elsewhere except in the priestly legislation of the Pentateuch. And this bears witness to a clear perception on the part of the prophet of the value of that whole side of things for the future development of religion in Israel. No one was more deeply impressed with the evils that had flowed from a corrupt ritual in the past, and he conceives the final form of the kingdom of God to be one in which the blessings of salvation are safeguarded by a carefully regulated system of religious ordinances. It will become manifest as we proceed that he regards the Temple ritual as the very centre of theocratic life, and the highest function of the community of the true religion.
