To hear tell, geocentrism, the ancient doctrine that the earth is fixed motionless at the center of the universe, died over four centuries ago. At that time Nicolaus Copernicus (picture below), a Polish canon who dabbled in astrology, claimed that the sun and not the earth was at the center of the universe. His idea is known as heliocentrism. It took a hundred years for heliocentrism to become the dominant opinion, and it did so with a complete lack of evidence in its favor.

Copernicus Yet the victory of heliocentrism has been less than total. Over the years geocentrism has had its spokesmen. Among scientists who adhered to the centrality of the earth were three generations of Cassinis: a family of astronomers who dominated French astronomy from the late seventeenth to the early nineteenth centuries. Astronomers, pastors, and educators in the Missouri Synod of the Lutheran Church maintained the geocentric truths well into the twentieth century. They, with the reformers such as Luther, saw that the embracing of heliocentrism would weaken not only science, but also the authority of the Bible.
