I had no idea he said these nice things about the Church until I read this article
If the link doesn’t work the time is WWII in Nazi Germany and the quote is as follows
the best tribute to the spirit of Germany’s Christians comes from a Jew and agnostic (TIME, Sept. 23) — the world’s most famous scientist, Albert Einstein. Says he:
“Being a lover of freedom, when the revolution came in Germany, I looked to the universities to defend it, knowing that they had always boasted of their devotion to the cause of truth; but, no, the universities immediately were silenced. Then I looked to the great editors of the newspapers whose flaming editorials in days gone by had proclaimed their love of freedom; but they, like the universities, were silenced in a few short weeks. . . .
“Only the Church stood squarely across the path of Hitler’s campaign for suppressing truth. I never had any special interest in the Church before, but now I feel a great affection and admiration because the Church alone has had the courage and persistence to stand for intellectual truth and moral freedom. I am forced thus to confess that what I once despised I now praise unreservedly.”
