For more than a decade, Catholic priest, teacher and vice principal David Edwin Rapson raped and sexually abused a number of Victorian schoolchildren.
Decades after committing the abuse, 60-year-old Rapson has been found guilty of indecently assaulting eight boys.
Rapson, who was defrocked by Pope John Paul II after his first sexual abuse conviction, abused the boys during his time at Salesian College's Lysterfield and Rupertswood campuses between the 1970s and 1990.
He denied the allegations but a jury on Friday found him guilty of all five charges of rape and eight counts of indecent assault.
During his nine-day trial in the Victorian County Court, prosecutor David Cordy said Rapson had abused the boys, sometimes with witnesses around, and thought he could not be held accountable.
"You can imagine just the relative power ... between the parties," Mr Cordy told the jury.
"If anyone said anything, it was just going to be swept under the carpet - that's the way it was back then."
Rapson was a junior priest at Lysterfield in the 1970s, before becoming a teacher and vice principal at Rupertswood.
His barrister Shaun Ginsbourg had told the trial that Rapson gave some children cigarettes and alcohol but denied all of the abuse allegations.
Mr Ginsbourg said the time since the incidents made it difficult to test the evidence against him.
"The lapse of time should make you more careful in accepting that these allegations are true," he told the jury.
However, Mr Cordy said it often took a long time for sexual abuse victims to tell their stories.
"The mills of God grind slow," he said.
Rapson was jailed for two years in 1992 after being convicted of the sexual abuse of a boy at Rupertswood.
He was removed from the priesthood in 2004 after the Australian head of the Salesians travelled to the Vatican to personally ask Pope John Paul II to defrock him.
Rapson showed no emotion as his verdict was read to the court.
He will face a pre-sentence hearing on October 9.
