The Gospel Readings since the end of January have been on Matthew's "Sermon on the Mount," particularly Chapter 5. "The Law and the Prophets" serves as a hermeneutical key when reading these passages.
My Jewish teachers in graduate school taught us that one of the best ways to understand the Hebrew Bible--especially the Law (Genesis to Deuteronomy) and the Prophets (Joshua, Judges, Samuel, Kings, Isaiah, Jeremiah, Ezekiel, and the Twelve [Hosea to Malachi])--is to focus on who speaks for God in these traditions.
In the Law, God speaks through Moses. In the Prophets, God speaks through Elijah (and Elisha, Deborrah, Samuel, and the rest of the prophets). In our lection (and in the gospels), God speaks through Jesus.
My friends, God speaks through anyone God chooses. God especially speaks through those whose lives proclaim good news to the poor, freedom for the prisoners, recovery of sight for the blind, liberation for the oppressed, and God's Jubilee of justice!
Lest we forget: Moses, Elijah, and Jesus are not, and never have been, Christians. Those of us who take pride in calling ourselves Christian should stop thinking that we have exclusive access to God.
