Prophecy is a major theme in the Old Testament. Elijah and Elisha are prophets who called Israel to a faithful worship of God. Nathan and Gad served as royal advisors to King David. Scholars refer to the prophets who left us something in writing as canonical prophets. The first of these is Amos. For three crimes of Israel, and for four, I will not revoke my word; Because they sell the just man for silver, and the poor man for a pair of sandals. One definition of a canonical prophet: someone who feels the pain of others. Amos denounced a society which exploits the poor. At our baptism we are anointed as prophets — and, hence, should feel the pain of racism, war, homelessness, hunger, etc.
