A woman’s personal conviction to begin keeping the seventh-day Sabbath in 1926 would challenge her husband to begin an intensive study to prove her wrong. That study would spawn a new religious movement under Herbert W. Armstrong. A fledgling group would form in 1934, and an audacious media operation would make the Radio Church of God (later re-named the Worldwide Church of God) grow by 30% per year over the next 35 years.
