The problem was, he didn't just support Copernicus's idea, and he did not stick to teaching it as a theory, as the church allowed him to do. His problem was that he promoted it aggressively as the absolute truth, and that is what put him on a collision course with the Vatican. He was tried for heresy because he was held to be trying to reinterpret The Bible.
Copernicus's theory, as promoted by Galileo, was eventually replaced by Kepler's theory, but the idea of having the Sun at the center was retained. In the 18th century the discovery of the law of gravity and the laws of motion showed that Kepler's model was very close to reality, and it's the model in use today with slight modifications from relativity.
