Joseph Priestley and Thomas Jefferson both applied scientific principles to Christianity.
Joseph Priestley, a Unitarian minister and a chemist who identified oxygen, advocated a theology that was equal parts religion and science. He believed that any religious thinking that failed to meet scientific muster should be revised. Priestley’s provocative views inspired his friend Thomas Jefferson to create an edited version of the biblical Gospels by cutting and pasting only parts that could be proved through reason or evidence.
