Thomas Erastus, Swiss physician and theologian (born 1524)

Thomas Erastus was a Swiss physician and Calvinist theologian. He wrote 100 theses in which he argued that the sins committed by Christians should be punished by the State, and that the Church should not withhold sacraments as a form of punishment. They were published in 1589, after his death, with the title Explicatio gravissimae quaestionis. His name was later applied to Erastianism.
