Duane Alexander Miller was born in Montana and grew up in Colorado and Puebla (in Mexico). He completed a BA in philosophy at the University of Texas at San Antonio (UTSA) and then an MA in theology at St Mary's University (also in San Antonio). Later life took him to Jordan where he and his wife studied Arabic, to Israel where he helped found a seminary, and to Scotland for doctoral work, among other places. He now lives in Madrid where he teaches and ministers, interested in the interactions of Islam, Christianity and secularism in modern contexts. His main areas of research for his PhD in divinity were religious conversion from Islam to Christianity, contextual theology, and the shari'a's treatment of apostates. He has also published research on global Anglicanism and the history of Anglican mission in the Ottoman Empire and had the pleasure of teaching in many places over the years: from Costa Rica to Turkey, and Kenya to Tunisia. He is Associate Professor at the Protestant Faculty of Theology at Madrid (UEBE) and priest at the Anglican Cathedral of the Redeemer in Madrid, Spain.
