Monsignor Kevin McGinnell discusses with Professor Tom O’Loughlin one of the most remarkable, but least remarked upon, developments among Christian churches working together in recent decades: the appearance of the Revised Common Lectionary for their Sunday worship. They discuss its value for worship and its collateral value of helping Christians appreciate one another’s treasures. To read more about the Revised Common Lectionary, read the Reims Statement which can be found at http://www.jlg.org.uk/Reims.pdf
