Vincent Long Van Nguyen told a royal commission into institutional responses to child sexual abuse on Tuesday the abuse had a "powerful impact" on him.
The Catholic bishop of Parramatta - a suburb of Sydney - said: "I was also a victim of sexual abuse by clergy when I first came to Australia, even though I was an adult."
"That had a powerful impact on me and how I want to ... walk in the shoes of other victims and really endeavour to attain justice and dignity for them."
Bishop Vincent, the first Australian bishop from a Vietnamese background, urged the Church to consider removing priests' honorifics, claiming titles and privileges "breed clerical superiority and elitism".
His speech was listened to by child sexual abuse survivors and their loved ones who applauded his testimony and shed tears.
Bishop Vincent added: "How can I look at these victims in the eyes and say I share your pain, I share your suffering without doing everything in my power to bring about justice, dignity and healing for them."
Investigation institutional abuse in Australia, the royal commission has the power to call witnesses and recommend prosecutions.
Last week, the inquiry heard how the Catholic Church in Australia had paid compensation totalling £170 million (A$276 million) to thousands of child abuse survivors since 1980.
The latest hearing is expected to continue on Wednesday.
The inquiry is due to report back to the Australian government in December.
