“By 'God', I understand, a substance which is infinite, independent, supremely intelligent, supremely powerful, and which created both myself and everything else […] that exists. All these attributes are such that, the more carefully I concentrate on them, the less possible it seems that they could have originated from me alone. So, from what has been said it must be concluded that God necessarily exists”

“If God did not exist, He would have to be invented. But all nature cries aloud that he does exist: that there is a supreme intelligence, an immense power, an admirable order, and everything teaches us our own dependence on it.”

“From my own being, and from the dependency I find in myself and my ideas, I do, by an act of reason, necessarily infer the existence of a God, and of all created things in the mind of God.”

“Perhaps I am even envious of Stendhal? He robbed me of the best atheist joke which precisely I could have made: 'God's only excuse is that he does not exist'...I myself have said somewhere: what hitherto been the greatest objection to existence? God...”

“God is the supreme uncreated light of which Wisdom is born, but there was never a time when God's Wisdom did not exist.”

“For all works and things, which are either commanded or forbidden by God and thus have been instituted by the supreme Majesty, are 'musts.' Nevertheless, no one should be dragged to them or away from them by the hair, for I can drive no man to heaven or beat him into it with a club.”
