Albert Einstein
According to Skeptic, Albert Einstein has already answered this himself, and apparently he said: "he had casually mentioned to some journalist that hardly any German intellectuals except a few churchmen were supporting individual rights and intellectual freedom. He added that this statement had subsequently been drastically exaggerated beyond anything that he could recognize as his own".

Having a long-standing interest in verifying quotations, I turned to The Expanded Quotable Einstein,8 but it does not include this statement. So I wrote to its editor, Alice Calaprice. She was unsure about the statement but kindly referred me to Barbara Wolff at the Einstein Archives in Jerusalem. Ms. Wolff was able to answer my question: It turns out that the Einstein Archives contain an unpublished letter mentioning this topic specifically. Writing to Count Montgelas on March 28, 1947, Einstein explained that early in the Hitler years he had casually mentioned to some journalist that hardly any German intellectuals except a few churchmen were supporting individual rights and intellectual freedom. He added that this statement had subsequently been drastically exaggerated beyond anything that he could recognize as his own
Did Albert Einstein say this about the Catholic Church?
It would appear he does admit to making a statement, but the words were taken out of context and exaggerated to an extent that they were not words that came out of his mouth.
