Sin City found God on Friday ... 'cause a Las Vegas Golden Knights fan delivered a custom jersey to Pope Francis -- and the holiest guy on earth LOVED it!!!!
Unclear why a man came to the Vatican bearing the NHL gift ... but when he did -- and the pictures became public -- the Knights were thrilled, tweeting of the moment, "OMG!"
The jersey is awesome ... it's a custom sweater featuring the name "Pope Francis" on the back.
Of course, the Knights are officially done this season -- the Sharks took care of them in the first round of the Stanley Cup Playoffs in a super controversial, down-to-the-wire Game 7 finish.
