This first volume of the New Wineskins series introduces the very best of current research and reflection on congregational transformation among Australian Baptists. This volume’s authors share the conviction that Baptist congregations must find new ways of engaging with the increasingly secular context of Australia. Collectively, they take the view that this requires congregations to remain spiritually vital, practically engaged, missionally relevant, and theologically authentic. The New Wineskins Symposium created a platform upon which our authors shared findings, made recommendations, and engaged in lively dialogue. The breadth of proposals and recommendations points to the need for an ongoing conversation. The volume’s editors hope that this series will catalyse a wider conversation and stimulate practical ministries among the many church and agency leaders who were unable to attend the original Symposium. Darren Cronshaw is a mission catalyst and researcher for the Baptist Union of Victoria, Melbourne. Darrell Jackson is the Senior Lecturer in Missiology at Morling College, Sydney. Both Darren and Darrell hold earned doctorates and are ordained Baptist ministers.
