Pope Benedict's former butler Paolo Gabriele has been ordered to stand trial on charges of aggravated theft for leaking documents alleging corruption in the Vatican.
In a 35-page document on the case, the Vatican also charged a computer expert who worked in the Vatican bureaucracy with involvement in the case.
The layman, named as Claudio Sciarpelletti, has been ordered to stand trial, although on lesser charges of aiding and abetting a crime.
The Vatican said it was not clear when the trial would be held but it would not be before the end of September.
Vatican spokesman Father Federico Lombardi said the Pope, as the sovereign head of Vatican City, could intervene at any time to stop the trial or pardon Mr Gabriele.
Mr Gabriele worked in the Pope's private apartments serving him meals and helping him dress.
He could face six years in prison under the laws of the papal state if found guilty.
According to the document, Mr Gabriele told investigators he had acted because he saw "evil and corruption everywhere in the Church".
He said he wanted to help root it out "because the Pope was not sufficiently informed".
In a section that referred to Mr Gabriele's state of mind, he told investigators that after he had started copying documents and leaking them, he "reached the point of no return and could not control myself any more.
"I was sure that a shock, perhaps by using the media, could be a healthy thing to bring the Church back on the right track."
The indictment order also revealed that a cheque made out to the Pope for €100,000, a gold nugget and a 16th century book were found in Mr Gabriele's house in a search, objects which the butler said he intended to give back.
The documents leaked earlier this year alleged corruption in the Vatican's dealings with Italian companies, including the payment of inflated prices for services, and detailed rivalries between cardinals and clashes over the running of the Vatican bank.
