The Commission on Mission engages with the churches in their call to mission and evangelism, relating the Gospel to contemporary society and cultures. It does so with explicit awareness of, and regard to, the Australian Aboriginal and Islander communities, the multicultural churches, the multifaith and secular environment.

Within the context of encouraging the churches to move towards greater visible unity in worship, common life and mission in Christ, the Commission:

contributes to a developing missiology and works with member churches to clarify issues involved in the relationship between the Gospel and cultures within Australia - Indigenous, Western and others.

explores current mythologies of what it means to be 'Australian' and the values supporting current economic, political and social policies, and develops means by which the churches together demonstrate the creating, reconciling and transforming love of God.
