" His belief in a Creator was a precondition to his physical theories."
No it wasn't, it was a coincidence. And now you are calling it *belief in a Creator* when before you said it was *Divine Revelation*. That is a very different thing. Name one part of Galileo's theories that relies on supernatural causes (which was the original point of contention). Name one part of Galileo's theories that relies on Divine Revelation.
Coincidence? No, these beliefs were essential to Galileo's thought. If you insist on characterizing God's actions as supernatural causes, then understand my point that Galileo took for granted that God was the FIRST Cause and that HE had provided Galileo with the sand box he was allowed to play in.
