The Daughter of Babylon, the True History of the Worldwide Church of God by Bruce Renehan documents the lies of Herbert Armstrong through thorough research, showing why the Worldwide Church of God was not the true church and could never be anything but a failure.
Particularly pertinent is the expose of the outright lie that the Waldensians were Sabbath keepers and held annual festivals. Mr. Renehan went straight to the source and inquired directly to the people who were competent to know the truth -- the Waldensians themselves.
