Marion is more worked up about this issue than if I had blasphemed or been promoting heresy. Why should you care so much?
Everyone knows that the so-called "Copernican Revolution" destroyed the Faith of the Church. Now you come up with flat earthism, claiming that Gallilei was wrong and the Church was wrong.
Your lack of general knowledge doesn't seem to allow you to grasp the consequences of your flat error. The "Copernican Revolution" destroyed all sane philosophy. It turned philosophy of God, being, and reality into philosophy of humans not able to grasp reality, not able to grasp the essence of a single thing. The tent-nail of realism was pulled, and relativism, liberalism, modernism is the result.
Flat-earthism is when the tent was flattened after the tent-nail was removed.
