Religious life
De Benneville had a mystical experience and later a near death experience that he described in The Life and Trance of Dr. George De Benneville. These experiences convinced him that Hell was for purification, not punishment, and that, ultimately, all souls would be united with God.
He believed that God is absolutely good and loving and would never condemn any human to eternal damnation. He also believed that each human being has a dualistic nature, and that the outer, flesh-and-blood person, subject to the evils of the world, could choose to do good or to do wrong, while the inner, spirit-like person, crafted by God and perfect, immaculate and holy, could never be damned. As a result, he was convinced that all human beings experienced salvation.
He preached and practiced medicine in France and Germany, but as religious authorities across Europe grew more and more disturbed by the increasing visibility of evangelists, de Benneville and others were sentenced to death more than once. After completing medical training in Europe, he chose to emigrate, and arrived in the American colonies during the mid-eighteenth century with others seeking religious tolerance.
After settling in Pennsylvania, he worked as a physician and apothecary in Oley, Berks County, using his free time to continue his Universalist preaching.
de Benneville also socialized and traded herbal preparations with Native American groups in the area. His beliefs stressed that all people everywhere were loved by God, and that cultures, races, and genders had no bearing on the worth of a human being. He also believed that the physical body was merely one part of a person.
