Question:
Answer:
You refer to the late Herbert W. Armstrong, who started the Worldwide Church of God.
Armstrong spuriously claimed that the British are the true descendants of the 10 tribes of the northern kingdom of Israel, which Assyria conquered and dispersed in captivity around 722 B.C. Armstrong claims without foundation that the descendants of these tribes migrated to the British Isles.
In addition, Armstrong also supported Saturday Sabbath worship, and he also didn’t believe in the Holy Trinity. After his death, the leaders of his Church accepted the Trinity and rejected “British Israelism.” Many of their congregations still worship on Saturdays, for example, but they no longer regard keeping the Jewish Sabbath and feasts as points of doctrine.
Unfortunately, there are still advocates of British Israelism (including some groups that split off from the Worldwide Church of God when it underwent its doctrinal renewal), and, though the book has been out of print, Armstrong’s The United States and Britain in Prophecy continues to circulate.
