Mason, Richard. The God of Spinoza: A Philosophical Study. Cambridge: Cambridge University Press, 1999.

From the publisher:

“This book brings together Spinoza’s fundamental philosophical thinking with his conclusions about God and religion. Spinoza was born a Jew but chose to live outside any religious community. He was deeply engaged both in traditional Hebrew learning and in contemporary physical science. He emerges not as a rationalist precursor of the Enlightenment but as a thinker of the highest importance in his own right, both in philosophy and in religion.”
