What theory did the catholic church believe in?

The Catholic Church historically upheld the theory of the geocentric model, which posited that the Earth was the center of the universe and that all celestial bodies revolved around it. This view was largely influenced by ancient philosophers like Aristotle and Ptolemy. However, during the Renaissance, the heliocentric theory proposed by Copernicus began to challenge this belief, leading to significant theological and scientific debates within the Church. Ultimately, the Church's position evolved, especially after the acceptance of scientific discoveries that supported the heliocentric model.
