I read some time ago he was an atheist until he got older then converted to Christianity. I hope that is true.

Kirk is Jewish.
He was born Jewish, of Russian Ashkenazi immigrant parents. Birth name was Issue Danielovitch, dirt poor son of a ragman. I read his autobiography years ago and he returned late in life to his roots in Conservative Judaism. But politically he was always a New Deal Liberal.
