Paolo Gabriele's sentence was originally three years but was reduced, partly because he was aware of "betraying the Holy Father's trust."
Catholics who participate in events connected with the 2012-2013 Year of Faith can receive a special indulgence, the Vatican said.
The 49-year-old Italian climbed the dome Tuesday to protest Italy's economic policies.
Vatican police officers who searched Paolo Gabriele's apartment testified they found "an infinite amount" of documents and news clippings.
Paolo Gabriele said he was innocent of charges of aggravated theft, but "I feel guilty for having betrayed the trust the Holy Father placed in me."
Catholics should rejoice, and not be jealous, when other Christians succeed in doing the work of the Lord, Pope Benedict XVI said.
"God can do good and even amazing things outside the circle" of the Catholic church, the pope said Sunday, commenting on the day's Gospel reading during his midday Angelus address.
A Vatican tribunal determined the two suspects indicted for their parts in the VatiLeaks' scandal should be tried separately.
VATICAN CITY -- Choosing men and women from every part of the world and from a wide variety of professions, Pope Benedict XVI nominated 45 experts and 49 observers for the upcoming world assembly of bishops.
The Oct. 7-28 gathering will include the largest bloc of women -- 10 experts and 19 observers -- ever to participate in a world Synod of Bishops. The special Synod of Bishops for Africa in 2009 had 10 experts and 20 observers who were women.
CASTEL GANDOLFO, Italy -- Defending traditional marriage is not an expression of backward thinking, said Pope Benedict XVI, but of values essential to the future of humanity.
"Marriage and the family are institutions that must be promoted and defended from every possible misrepresentation of their true nature, since whatever is injurious to them is injurious to society itself," he said.
VATICAN CITY -- An Italian startup is launching a web advertising platform that aims to provide Catholic websites with Catholic-approved advertisements.
The platform, called AdEthic, will be presented Thursday at a press conference in Rome, as part of a wider Catholic project to engage in social media.
According to Andrea Salvati, a manager at Google Italy who will take the role of CEO at AdEthic in October, the platform wants to tap into the vast Catholic online market that has so far been unable or unwilling to use advertisements.
Many Catholic webmasters are "scared" that inappropriate advertisements, such as sexually related content or messages from "bogus religious groups," will be displayed on their pages by context-sensitive automatic ad generators such as Google's AdSense, said Fr. Paolo Padrini, an Internet-savvy priest.
Padrini, who launched the iBreviary prayer app for iPhone last year, will head the ethics committee that will ensure the Catholic values of the platform's ad partners.
"We want to offer highly selected, high-quality, controlled advertisement to the Catholic online world," he said.
