'Terminator' Star: Priest Blesses Harley-Davidson ... Ride On, My Son

Robert Patrick knows the dangers of the road, which is why he took his brand new Harley-Davidson to church to get it blessed.

Patrick -- best known as T-1000 from 'Terminator 2' -- took his hog to St. Thomas, the Apostle church in Hollywood, and got it blessed courtesy of Father Ian Elliott Davies. It's the second bike Patrick's made holy.

As for how it's done ... some words by the good Father, with a sprinkle of holy water before Sunday mass.

Patrick's endgame ... protecting him from harm as he tools down the highway.
