Until Galileo, the idea that the earth, not the sun, was the center of the universe was highly accepted throughout the world. The first documented theory of a heliocentric universe surfaced around 310 – 230 BCE with Aristarchus of Samos. After this, however, the geocentric theory dominated society for over one thousand years. Ptolemy and Aristotle, both ancient Greek scientists and astronomers, popularized the earth-centered universe. They believed that ten concentric spheres constructed the cosmos, with a fixed and motionless earth at its center.

The Council of Trent, called by Pope Paul III, took place from 1545 to 1563. This meeting of cardinals, archbishops, abbots, bishops, and theologians met in Trent to discuss how to best combat Protestantism. The largest argument between these church leaders consisted of whether to compromise their doctrines to encourage the return of Protestants to the Church, or to reiterate traditional teachings in strong opposition to the Protestants. The latter group’s position won out, and the Council of Trent created a strict body of doctrine for Catholics that unified Christendom and reaffirmed traditional
