Correct. And Einstein believed in neither. "My position concerning God," he said, "is that of an agnostic."
I suggest you go do a little research about different religions before you start disputing them.
And I'd suggest you know perhaps a little less about this topic than you think.
I happen to believe in God; my faith in God isn't shaken because I recognize that Einstein wasn't a believer. There are things that I believe in that Einstein didn't, with quantum theory somewhat near the top of the list; there are also things that Einstein believed in (like socialism) that I have little use for.
Closer to correct...he was a gnostic. Spinozism is the pantheistic philosophical system of Baruch Spinoza which defines God as a singular self-subsistent substance, and both matter and thought as attributes of such. Spinoza claimed that the third kind of knowledge, intuition, is the highest kind attainable. This is in keeping with the thinking of the illuminate....which believes the upper level of human intelligence is essentially fluent with God and the Universe.
