Seventh-day Adventists
The adventist movement was founded by William Miller in the mid-1800s. He made a prediction of the second coming that failed. Not long after, a woman by the name of Ellen G. White said that the prophecy was indeed accurate but happened in the heavens, when Christ took his seat at God's right hand. She became the founder of the Seventh-day Adventist Church. All other adventist organizations in the United States can be traced back to either Miller or White, including the Jehovah's Witnesses, the Sacred Name groups, and the Worldwide Church of God.
The Seventh-day Adventist Church has an extensive worldwide missionary effort. Adventist World Radio broadcasts in some neat languages. I list many of them in my language skeds (please see home page). I also list the entire AWR sked separately.
They also host a popular program called the The Voice of Prophecy.
Worldwide Church of God
Watch America is sponsored by the Congregation of God Seventh Day, which can be traced back to the Worldwide Church of God, founded by Herbert Armstrong. He believed in celebrating the Old Testament feast days. It was a secretive church that didn't advertise.
The WCG hardly exists as such anymore. It became a member of the National Association of Evangelicals, thereby losing its distinctive doctrines. There are up to several hundred successor churches, although the churches described here splintered before the NAE membership.
The Church of God (O'Beirn) is also derived from the Worldwide Church of God. It's founder is Carl O'Beirn. His program is simply called Bible Commentary and can be heard on WINB.
Sacred Name
The Sacred Name movement began with the publication of The Faith magazine, which eventually moved to Eaton Rapids, MI. The magazine is affiliated with a local assembly there.
WMLK is sponsored by the Assembly of Yahweh in Bethel, PA. They believe that Yahweh is the proper name of God and Yahshua the proper name of Jesus. They use these names exclusively. They believe that the New Testament was originally written in Hebrew.
Yahwah Ministries is a Sacred Name Group that can be heard on WWCR.
Their homepage specifically says that they are not racist. Racism has plagued the more extreme Sacred Name Groups. (I can't think of a connection between the sacred name and racism.) The Bethel and Eaton Rapids assemblies are not racist.
Bible Students
Charles Taze Russell founded a movement derived from the Seventh Day Adventists. He referred to his followers simple as Bible Students. The largest and most famous Bible Student Group is the Jehovah's Witnesses.
The next largest group is the Dawn Bible Students. They-unlike the Witnesses-publish all six of Russell's books, volumes 1-6, for a cheap price. Russell's theology is difficult. They can be heard on various radio stations as follows:
Church of God Seventh Day
The Merry Street Church of God can be heard on WWCR. They announce themselves as being affiliated with the Church of God Seventh Day. There are, however, several groups that go by this name. All of them have roots in Michigan.
Gilbert Cranmer was a Seventh-day Adventist from Michigan. He founded his own church. This church, plus several others, combined to form the Church of God Seventh Day movement, which has a confusing history of divisions. C.O. Dodd, who founded the Faith magazine, was one of the founders of the Eaton Rapids Assembly of Yahweh. He too, was affiliated with the seventh day COG movement.
I could not find this church listed on the following websites but they're interesting for their theology. They are little known.
Church of God General Conference
Church of God 7th Day
British Israel/Anglo Israel
The British Israel World Federation represents a view called British or Anglo-Israelism. They believe that the people of Great Britain and its former colonies are God's chosen people. The American Encyclopedia of American Religions states that these groups began with a pro-Israel intent. They helped with various pro-Israel, pro-Jewish causes.
Now that has changed. The announcer for the program is calm, but is committed to a more exclusive view of Christianity. There is no explicit mention of exclusion, at least that I've heard, but he's old school.
