Sports officials now hope clergymen from 50 nations can bring back faith to soccer as they take to the pitch for the first time in a tournament for priests and seminarians kicking off on Saturday.

The Clericus Cup will run through June and most games will be played at a Vatican soccer pitch in Rome. The matches will last one hour and rules will differ from regular club football. Teams will be allowed one time-out and the referee will brandish a blue card, which will send off errant players for a five-minute suspension.
