Why would he hide his catholic history. he worked with the catholic church even though he wasnt exactly a fan.
He hated all religion and was a god onto himself as far as he was concerned.
He forged his paperwork to hide something. I suspect coming from a catholic family wouldnt of meant much. Coming from a jewish family would of meant his removal from the Nazi party.
Of course we will never know.....he died in 1945.........possibly....or in South America
