Frank Brennan has been a long time advocate for human rights and social justice in Australia. This collection of essays brings together some of his major addresses and writings on justice in the Catholic Church and in Australian society. Placing the individual’s formed and informed conscience as the centre piece in any work for justice, he surveys recent developments in the Catholic Church including the handling of child sexual abuse claims and the uplifting effect of the papacy of Francis, the first Jesuit pope. He then applies Catholic social teaching and the jurisprudence of human rights to contested issues like the separation of powers and the right of religious freedom, and to the claims of diverse groups including Aborigines, asylum seekers, the dying, and same sex couples. At every step, he is there in the public square amplifying that still, small voice of conscience, especially the voice of those who are marginalised.
