Sparks may fly this week with the first testimony in the Vatican's controversial trial over leaks of confidential documents that revealed waste, mismanagement and greed in the Catholic Church's hierarchy.

Two journalists face up to eight years in prison if convicted of putting pressure on a Vatican monsignor to obtain the documents and publish them. The monsignor and two other people affiliated with a papal reform commission are also on trial, accused of giving the journalists the information.

The trial resumes Monday after a three-month delay to give the defense time to prepare and experts time to go through text message and other evidence. Earlier, the Vatican had come under sharp criticism that it was rushing the trial and that the defendants weren't getting a fair shake.
