Prior to a We Hold these Truths vigil at a Christian Zionist church or event, a letter is sent to the pastors to let them know we're coming and why we are coming.  In preparation for the second vigil at a Washington, DC, Christian Zionist, mega-church, McLean Bible Church, Chuck Carlson sent a letter to the pastor, Lon Solomon and copied his staff.  This is a very insightful look at the disciples of Christian Zionism.
