Yet it was from the Renaissance that modern Secular Humanism grew, with the development of an important split between reason and religion. This occurred as the church's complacent authority was exposed in two vital areas. In science, Galileo's support of the Copernican revolution upset the church's adherence to the theories of Aristotle, exposing them as false. In theology, the Dutch scholar Erasmus with his new Greek text showed that the Roman Catholic adherence to Jerome's Vulgate was frequently in error. A tiny wedge was thus forced between reason and authority, as both of them were then understood.
