The internet has many places where personal letters to many different people by Einstein have been posted.
Those letters reveal that the scientist could not really be characterized as even a deist.
Max Jammer, author of "Einstein and Religion", was Professor Emeritus of Physics, a colleague and friend of Einstein, author of a number of treatises on the foundations of physics (including one which Albert Einstein had written a preface), and his "Philosphy of Quantum Mechanics" was reviewed in draft by paul Dirac and Werner Heisenberg.
In writing "Einstein and Religion" Jammer used the Einstein Archive at the National and University Library in Jerusalem, and the library of the Union Theological Seminary in new York.
If you place more credibility on isolated quotes found on the internet over the scholarly and comprehensive work of a world reknowned philosopher and scientist that is certainly your prerogative.
Jammer says Einstein believed in an impersonal God. My studies on Einstein are consistent with that conclusion.
If you have credible information that contradicts then feel free to post it. I have posted my data and sources supporting my position. I will keep an open mind, but the bar for credible data is set high.
