Cardinal George Pell has denied claims he tried to bribe the nephew of paedophile priest Gerald Ridsdale to stay quiet about the sexual abuse he suffered at the hands of his uncle.

David Ridsdale told the Royal Commission into Institutional Responses to Child Sexual Abuse yesterday that in 1993 after being informed of the abuse Cardinal Pell asked him what it would take for him to stay quiet.

"George then began to talk about my growing family and my need to take care of their needs. He mentioned how I would soon have to buy a car or house for my family," Mr Ridsdale said.

"I want to know what it will take to keep you quiet," Mr Ridsdale quoted Cardinal Pell as saying.

In a statement released late on Wednesday, Cardinal Pell again denied those allegations.

"At no time did I attempt to bribe David Ridsdale or his family or offer any financial inducements for him to be silent," the statement said.

"At the time of our discussion the police were already aware of allegations against Gerald Ridsdale and were investigating. Then, and now, I supported these police investigations."

Cardinal Pell said he regretted the "misunderstanding" between him and David Ridsdale.

"I was and remain extremely sympathetic to David Ridsdale, who because of his uncle suffered horrible abuse," he said.

"I continue to regret the misunderstanding between us."

In the statement, Cardinal Pell also denied ever moving Gerald Ridsdale out of Mortlake Parish.

"I never moved him anywhere. I would never have condoned or participated in a decision to transfer Gerard Ridsdale in the knowledge that he had abused children, and I did not do so," he said.

Pell denies conversation with Ballarat victim

Cardinal Pell also repeated his claims that he has no recollection of a conversation with survivor Timothy Green in 1974, regarding Brother Edward Dowlan.

Mr Green told the inquiry that the cardinal was dismissive when he reported that Brother Dowlan was abusing boys at St Patricks College in Ballarat.

"He just dismissed it and walked out. His reaction gave me the impression that he knew about Brother Dowlan, but couldn't or wouldn't do anything about it," Mr Green said.

But Cardinal Pell said he stood by his statements to previous inquiries.

"As I have stated previously, I have no recollection of a conversation with Mr Green in 1974, more than 40 years ago," the statement said.

"To the best of my belief, this conversation did not happen."

In his statement Cardinal Pell condemned the "profoundly evil" abuse by clergy in the Church and said "suicide of so many victims is an enormous tragedy".

The royal commission said it would request a further statement from Cardinal Pell in response to the allegations.

"I am committed to complete cooperation with the Royal Commission," Cardinal Pell said.

"I will address in full all matters it wishes to raise in any statement requested from me before I make any further comment."
