Calvin Approves of "Occasionalism"

That Providence, therefore, which we ascribe to God, pertains as much to His operating hands as to His observing eyes. When, therefore, God is said to rule the world by His Providence, we do not merely mean that He maintains and preserves that order of nature which He had originally purposed in Himself, but that He holds and continues a peculiar care of every single creature that He has created. And true and certain is the fact, that as it was the wonderful wisdom of God that originally made the world, and disposed it in its present beautiful order, so, unless the omnipotent power of God, ever present, sustained it thus created and disposed it, it could not continue in its designed order and form one hour.  -- John Calvin
