The church's granted indulgences reduce the time Catholics believe they will have to spend in purgatory after they have confessed and been absolved of their sins.
The remissions got a bad name in the Middle Ages because unscrupulous churchmen sold them for large sums of money. But now indulgences are being applied to the 21st century.
But a senior Vatican official warned web-surfing Catholics that indulgences still required a dose of old-fashioned faith, and that paradise was not just a few mouse clicks away.
"You can't obtain indulgences like getting a coffee from a vending machine," Archbishop Claudio Maria Celli, head of the pontifical council for social communication, told the Italian daily Corriere della Sera.
