Howard Mowll was the enterprising and indefatigable Archbishop of Sydney from 1934 to 1958. At once robustly Anglican and evangelical in outlook and policy, he set the diocese of Sydney on the course it has followed to the present day. Originating in the Moore College Library Day of 2021, the essays in this book cover previously overlooked and neglected aspects of Mowll's leadership and administration as well as providing new insights into and fresh perspectives on his life and work in Sydney. They also give due attention to the equally remarkable contribution of Mowll's wife, Dorothy. Based on extensive archival research, and paying attention to the context of mid-twentieth century Australia, these essays begin the task of historical assessment by both extending and qualifying the biography provided by Marcus Loane in the immediate aftermath of Mowll's death. Was Mowll one of the two truly great Bishops/Archbishops of Sydney, as Peter Jensen suggests in the Introduction? This book both invites and enables readers to decide for themselves.
