I never understand the idea that Spinoza was an atheist. Sure his ideas of God were not Judeo-Christian but he did believe in the super-natural that we see in action through nature. Spinoza was 100% a theist and wrote about God and advocated for the evidence of a God. I almost laugh when agnostics try to use him as their champion. They are ramming their own beliefs into this Philosopher that it is not respectful to Spignoza's writing. My example is since he saved Ethics to be released on his death why wasn't he clear on the rejection of God or place more on Deist statements?

Prop. 28

"The mind's highest good is the knowledge of God, and the mind's highest virtue is to know God. ...The mind is not capable of understanding anything higher than God, that is, than a Being absolutely infinite, and without which nothing can either be or be conceived; therefore, the mind's highest utility or good is the knowledge of God. Again, the mind is active, only in so far as it understands, and only to the same extent can it be said absolutely to act virtuously. The mind's absolute virtue is therefore to understand."
