The Complete Guide to American Denominations and Christian Organizations. Nelson's Guide to Denominations provides essential data on 800+ Protestant and Catholic churches operating in the United States and Canada, plus ecumenical and cooperative associations and parachurch organizations. Every entry reports the name of the group, a brief history, key leaders or a contact person, address, email and/or website, membership stats, unique features, world mission affiliates, and sidebars on special ministry initiatives. The guide also includes a section on trends and prospects for the church in North America and a symposium on the Bible in America.
