Miguel Serveto, AKA Michael Servetus, was a Spanish-born medical physician, astronomer, and Christian theologian from the 16th century who is mostly famous for expressing a radical view of the Father-Son-Spirit trinity, in a way that could be considered a derivation of the Arianist doctrine from Late Antiquity. He was also an Unitarian, arguing that church organizations were tainted by the profane matters of state. He was arrested by the inquisition at Lyon around 1552 and sentenced to death, but managed to escape to Geneva. There, Servetus met the Protestant leader John Calvin, who, unfortunately, also had contemptuous opinions towards his ideology. Calvin sentenced Servetus to burning at the stake, an act which drew serious criticism upon him by the local Protestant community. The spaniard's teachings would leave a small legacy in the form of the Unitarian movement. So, my question is... how can we make it so that Servetus becomes as influential as Luther or at least Calvin in the grand scheme of the 16th century Reformation? Who could his ideology appeal to?
