At no time did he believe in a personal God and in 1950, 5 years before his death was an agnostic.
In 1954 he wrote that lies about his religious convictions were systematically repeated.
1929
On 24 April 1929, Einstein cabled Rabbi Herbert S. Goldstein in German: "I believe in Spinoza's God, who reveals himself in the harmony of all that exists, not in a God who concerns himself with the fate and the doings of mankind."[15] He expanded on this in written answers he gave to a Japanese scholar on his views on science and religion, which appeared as a limited edition publication, on the occasion of Einstein's 50th birthday:
Scientific research can reduce superstition by encouraging people to think and view things in terms of cause and effect. Certain it is that a conviction, akin to religious feeling, of the rationality and intelligibility of the world lies behind all scientific work of a higher order... This firm belief, a belief bound up with a deep feeling, in a superior mind that reveals itself in the world of experience, represents my conception of God. In common parlance this may be described as "pantheistic" (Spinoza).[16]
Pantheism is the belief that the universe (or nature as the totality of everything) is identical with divinity
1930
Einstein had previously explored the belief that man could not understand the nature of God. In an interview published in 1930 in G. S. Viereck's book Glimpses of the Great, Einstein, in response to a question about whether or not he believed in God, explained:
Your question [about God] is the most difficult in the world. It is not a question I can answer simply with yes or no. I am not an Atheist. I do not know if I can define myself as a Pantheist. The problem involved is too vast for our limited minds. May I not reply with a parable? The human mind, no matter how highly trained, cannot grasp the universe. We are in the position of a little child, entering a huge library whose walls are covered to the ceiling with books in many different tongues. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written.
1950
In a 1950 letter to M. Berkowitz, Einstein stated that "My position concerning God is that of an agnostic. I am convinced that a vivid consciousness of the primary importance of moral principles for the betterment and ennoblement of life does not need the idea of a law-giver, especially a law-giver who works on the basis of reward and punishment."[21]
1954
On 22 March 1954 Einstein received a letter from Joseph Dispentiere, an Italian immigrant who had worked as an experimental machinist in New Jersey. Dispentiere had declared himself an atheist and was disappointed by a news report which had cast Einstein as conventionally religious. Einstein replied on 24 March 1954:
It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.[9]
