After the sentences were read out, Bisceglie, a flamboyant figure in the Calabrian city of Cosenza, yelled out in court that the verdict was "shameful".
"You have sullied the reputation of an honest priest. This is the most painful chapter even written by magistrates in Cosenza," Bisceglie shouted.
He has been in prison since January 2006 for gang-raping the nun five times after drugging her, according to the prosecution.
Bisceglie`s lawyer Franz Caruso said he would wait for the court to issue its reasoning behind Wednesday`s sentences before commenting on the verdict.
"We need to see how the court overcame the many contradictions in the evidence it was presented with during the trial," he said.
Bisceglie founded a centre to the help the poor in Cosenza, was an avid fan of the city`s football team and was famous locally for having helped a porn star find religion.
