On the progressive side of the Church, much is made of "prophetic" speech or actions. The progressives are trying to bring the Church into the new truths to which they believe God calling them.
In truth, however, prophets do not bring people to new truths. There are very few (if any) "new truths." If we look at the biblical record, the prophets did not announce or proclaim anything new in terms of our relationship with God. They called people back to the covenant that they made with God.
One of the tasks of a deacon is to interpret to the Church the "needs, concerns, and hopes of the world." I take this to be a prophetic call to the Church to remember its covenant with God. As a deacon, I am to remind the Church of its obligations. I am to call her people back to their covenant.
Our covenant with God is found in the Baptismal Covenant found on pages 304-305 of the Book of Common Prayer. It is in two parts. The first part is our subscription to orthodox belief. It is the Apostles Creed in question and answer form. We state we believe certain things about God.
But the second part is much harder to listen to and to keep. The first question that we are asked (and that we answer affirmatively) is "Will you continue in the Apostles teaching and fellowship, in the breaking of the bread and in the prayers."
By answering "I will with God's help" we promise to eschew heretical belief, heretical practice, and schism. Because I answer this positively, I will not leave the Episcopal Church until I am kicked out. I will stay and be the prophet that God calls me to be. I will continue to call the Church back to her Baptismal Covenant.
