Herbert W. Armstrong was an American minister and founder of the Worldwide Church of God, established in 1934. He is best known for promoting a unique interpretation of Christianity, which included beliefs in the Sabbath, the Holy Days, and the idea of a coming Kingdom of God on Earth. Armstrong's teachings emphasized the importance of biblical prophecy and the need for personal study of the Scriptures. Armstrong was also a prominent figure in the media, using radio and television to spread his message. His program, "The World Tomorrow," reached millions of viewers and listeners. After his death in 1986, the Worldwide Church of God underwent significant changes, moving away from many of his original teachings.
