CoroUniting is a member of the ACC (Assembly of Confessing Congregations) movement within the Uniting Church. In a mainline denomination such as the Uniting Church there are many different understandings of the Christian faith, some of which have moved away from the heart of it. The overriding purpose of the ACC is to uphold the faith of the one, holy, catholic and apostolic church, as described in the Uniting Church’s Basis of Union.

ACC is a national body holding an annual conference and working on issues of theology, discipleship, relations with other churches as well as marriage and sexuality. It produces a nation-wide magazine, ACCatalyst.
