At the United Methodist Church's General Board of Discipleship site, you can find a PowerPoint developed by Safiyah Fosua, about the Revsied Common Lectionary. This presentation can help folks understand the organization of the lectionary and how the 3 year cycle of readings is laid out. The link is to a .ppt file, so you'll need either PowerPoint or the PowerPoint Viewer on your machine in order to see it. I've gotten many of requests for information like this from clergy and lay people both. Check it out!
