Previous stages which we have been able to recognise in the development of Israel's religion do not carry us on to Amos by so inevitable a movement, that his message could be predicted as the next stage to be reached. When we come fresh from the investigation of the religion held by the leaders of the people in the times of David and Solomon, we recognise the immense strides made when we open the Book of Amos. We can trace a likeness between Elijah and Amos in their denunciation of wrong; but, in the sphere of religion, there is a great gulf between them which no records of the intervening period quite help us to bridge over. We cannot think of Amos taking part in the great vindication of Carmel; it is probable that he would have recognised it as useless. In Samuel, Elijah and Elisha we undoubtedly have the religious ancestors of the Literary Prophets, but while they stood at the head of popular movements which they led in triumph against the intrusion of alien faiths, the Prophets that we are now to study stand in decided antagonism to the popular faith, and the conceptions of Israel's religion which they reiterate with such passion and insistency were never acceptable to the people. Their religion has to make its way against the national religion.
