Arnold Schwarzenegger -- The One-Finger Statement to Maria Shriver

Arnold Schwarzenegger rocked his wedding ring out in public during the holidays -- another sign that his marriage to Maria Shriver ain't as dead as it once seemed.

TMZ broke the story ... Maria has been having second thoughts about pulling the plug on the marriage -- despite Arnie knocking up the family maid -- because of her deeply held religious views.

Arnold hadn't been photographed in his wedding band in months, but over the past few days -- Arnold dusted off the ol' ring and reminded the world he's STILL a married man.
