 Michael Servetus (1511?–1553) stimulated thought in this direction and heavily influenced other reformers both by his writings and by his death at the stake.In 1531 he had published his theological treatise "De Trinitatis Erroribus" (On the Errors About the Trinity), in which he rejected the Nicene dogma of the Trinity and proposed that the Son was the union of the divine Logos with the man Jesus, miraculously born from the Virgin Mary through the intervention of God's spirit.This was generally interpreted as a denial of the Trinitarian dogma (actually Servetus had described the Trinity as a "three-headed Cerberus" and "three ghosts" which only led believers to confusion and error).
