SERVETUS, MICHAEL (MIGUEL) (15111553)

Michael Servetus was a Spanish physician who questioned the Trinity and believed that God is unitary. In Geneva while in flight from persecution in Italy, Servetus was captured and, on orders of John Calvin,* burned at the stake for heresy.

Servetus trained as a physician in Paris, though his many activities included studying theology and being a jurist. During his many travels throughout Eu­rope, Servetus met many religious reformers in Germany and Switzerland. These contacts fueled Servetus's own theological questionings, the result of which was his bookDe trinitatis erroribus(On the Errors of the Trinity, 1531). This book sparked much expected criticism from both Roman Catholics and Protestants.By questioning the Trinity, Servetus immediately brought upon himself the spec­ter of being a heretic. In 1540 Servetus became the first person to describe the pulmonary transit of blood. In 1553 he returned to his theological pursuits and published his main work,Chrisitianismi restitutio(Restitution of Christianity, 1553). Although the book was published under the pseudonym Michel de Vil­leneuve, it was common knowledge that Servetus was the actual author. Servetus was quickly condemned from all sides for his Antitrinitarian heresies, and in 1553 he was arrested in Geneva and, on orders of John Calvin, burned at the stake for his heretical views.

Servetus is cited as a founding figure within Unitarianism. Although Servetus did not himself establish Unitarianism as a separate sect, Unitarians have largely accepted his criticisms of the Trinity. Moreover, Unitariansm continue to accept a diversity of religious views, and they do so largely because they believe that Servetus was wrongly executed for questioning the dogmas of the day. Unitar­ians, Quakers, and others within the tradition of free, liberal religions find in Servetus a source of inspiration.
