Lena was born in 1875 in Michigan and after a brief spell as a teacher, she turned her attention to nursing. It was then that she met and married William S Sadler and the two pursued their medical careers together, graduating with equal honours at the American Medical Missionary College.
Kellogg had a distinguished career in women’s medicine, but at some unspecified time in the 1920s or 30s, the couple claimed that words of enlightenment had been given to them by a race of super-intelligent extraterrestrial beings called the ‘Revelators’ which was channelled through the medium of a comatose patient.
This became known as The Urantia Book, using the name that these cosmic beings supposedly use for the Earth. It was communicated to them to correct errors of religious thinking and also made pronouncements on subjects ranging from evolution to quantum physics.
It also included an updated biography of Jesus claiming, among other things, that he visited both Rome and Greece in his late twenties to study philosophy, mathematics and art.
Lena Kellogg died in 1939, long before the revelations were made public in 1955 when The Urantia Book was published by her husband. Parts of it make disturbing reading as the Sadlers were enthusiastic proponents of eugenics, a subject still being discussed by their followers today.
The Kelloggs were ardent Seventh Day Adventists and critics of The Urantia Book point out the similarities with Adventist doctrine and even suggest that the words may have been penned by John Harvey Kellogg himself.
