Why did the church support the geocentric theory

The Geocentric theory or model proposed that the Earth was the center of the universe and the Sun rotated around it. Religion played a big role throughout history in trying to perpetuate this scientifically erroneous idea, which started appearing as a biblical perspective pointing towards specific passages in the holy book. A classic one would be Psalms 93:1, in which Earth is described as a static place "established, firm and secured". The church's support of geocentrism can be traced back to literal intepretations of the bible and a refusal to lose credibility and power as science proved them wrong.

Hope this helps!
