Which of the following best reflects the reason for ecumenism in Australia’s current religious landscape? (A) A shared concern for social justice issues (B) Increased awareness of the potential for interfaith dialogue (C) A decline in the number of Christian adherents in the population (D) The beginning of resource sharing including church buildings in rural Australia - HSC - SSCE Studies of Religion - Question 9 - 2009 - Paper 1

This option highlights the growing interest in dialogue among different faiths, which has indeed played a significant role in the ecumenical movement in Australia's diverse religious landscape.

This can contribute to ecumenism as denominations may seek to work together to maintain relevance, but it is more a consequence rather than a primary reason for ecumenism.

While resource sharing does reflect practical aspects of ecumenism, it is a result of the changing religious landscape rather than the fundamental reason behind ecumenical efforts.
