Scripture is a book about going to Heaven. It's not a book about how the heavens go.

Nature is relentless and unchangeable, and it is indifferent as to whether its hidden reasons and actions are understandable to man or not.

Holy Scripture could never lie or err...its decrees are of absolute and inviolable truth.

Long experience has taught me this about the status of mankind with regard to matters requiring thought: the less people know and understand about them, the more positively they attempt to argue concerning them, while on the other hand to know and understand a multitude of things renders men cautious in passing judgment upon anything new.

God is known by nature in his works, and by doctrine in his revealed word.

Take note, theologians, that in your desire to make matters of faith out of propositions relating to the fixity of sun and earth you run the risk of eventually having to condemn as heretics those who would declare the earth to stand still and the sun to change position-eventually, I say, at such a time as it might be physically or logically proved that the earth moves and the sun stands still.

Some, merely to contradict what I had said, did not scruple to cast doubt upon things they had seen with their own eyes again and again.
