The recent announcement from the Dicastery for the Causes of Saints that St John Henry Newman will be named a Doctor of the Church has special meaning for converts like me. For many of us, Newman’s Essay on the Development of Christian Doctrine (1845) and the Apologia Pro Vita Sua (1865) are the respective road map and debriefer‑by‑proxy of our journey into the Church. My own conversion was directly related to Newman’s “rediscovery” of the theology of the Apostolic Fathers and his recovery of the historical development of early Christian doctrine.
