One of the Catholic Church's most outspoken and loved leaders has encouraged his fellow clergy to keep the pressure on the Vatican to reform, as he prepares to retire.
Father Pat Power has resigned after more than 25 years as the bishop of Canberra and Goulburn.
He has become known as one of the church's more progressive leaders, questioning the need for priests to be celibate and for women to be excluded from senior roles.
Father Power says the sexual abuse scandals have diminished the authority of the church and warns that unless there is reform, parishes will continue to shrink.
"There's been the whole question of sexual abuse, which has brought a terrible stain on the life of the church," he said.
"But I think there's wider reform that's needed there and my great sadness is the fact that the second Vatican Council gave us the pathway, I think, for the church to be more accommodated to bring the message of Christ to the modern world."
Clergy shortage
He says the Catholic Church is in a "critical position" in Australia and may other parts of the world in terms of shortage of clergy.
"While we persist in this disciplinary world that Catholic priests in the Latin rite are not able to marry, there are just less and less young people coming into the priesthood," Father Power said.
"We're in a situation in our diocese, for instance, where we're just desperately short.
"I wrote to the Pope in 2010, talking about the situation in Wilcannia-Forbes and suggesting that in each of those parishes, good married men... after some training, could be ordained and serve the church there and I said what's happening there is progressively going to happen across the rest of Australia."
He says it was a message the Vatican did not want to hear.
"I think that's sad and I think a lot of times bishops are reluctant to speak as strongly as I have about it for fear that they're being disloyal to Rome," he said.
"But I think that it's important that we look at the life of the whole church.
I think as local bishops, we've got a responsibility to enable the Pope and his advisers to see what the real state of affairs is on the ground."
But while the 70-year-old says the hierarchy is deaf to concerns like his - he says he draws strength from the activities of the church's grassroots.
"I've just been to three of our Catholic schools here, high schools here in Canberra in the last little while, and just to see the good things that are happening on the ground there," he said.
"The life of the spirit is very much present in those situations and I think it's important that those grassroots manifestations of healthy church life can be brought to bear on the whole church."
