The Catholic Church in Australia has learnt some sharp lessons, Thursday's official submission to the royal commission shows.

The church, often described as the world's last mediaeval monarchy, seems to be coming reluctantly to terms with aspects of 21st century governance, which should not be confused with its unchanging magisterium, the official doctrines. Francis, elected Pope in March, has been promulgating a different attitude, wanting his cardinals to be pastors rather than princes, and the scandal-plagued Vatican bank has just disclosed its annual report for the first time.

This week, Sydney Archbishop George Pell is in Rome as part of the "G8" group of cardinals advising Francis on reforming the Vatican.

Not the least important lesson the Australian church has absorbed was the need to replace Cardinal Pell as its public face on the abuse issue.
