Massimo Bucciantini et al, authors of Galileo’s Telescope (2015) sums up the difficulties that orthodoxy had with Galileo’s findings.
If the Earth is a planet (like Venus) circling the Sun, then the Earth is in the sky. That means that the sky is corruptible like the Earth.
Then how can the sky continue to be the home of angels and saints?.
And how can Hell be at the center of the Earth, when the Earth is in the sky and thus is no longer in the region furthest from heaven?
