Raised in the Guadalupe community of San Antonio, Texas, Gabriel Radle moved to Rome at eighteen to pursue an education in philosophy and theology. The tangibility of history in that city's monuments persuaded him toward specialized work on Church history, and Christian art and architecture, subjects he also taught at the American University of Rome. Ultimately, his interests in the history of lived theology and the sacred arts intersected through a doctorate in comparative liturgical studies completed in 2013. Since then, Radle has held fellowships at Yale University's Institute of Sacred Music, Harvard University's Dumbarton Oaks Research Library, the Hebrew University of Jerusalem, and Princeton University.
Radle has published widely on the history of liturgy in both West and East. His publications include studies on Christian rites of passage, early Byzantine eucharistic texts, Mt Sinai liturgy, Hellenophone Christian migrations to Italy during the Arab conquest, liturgical posture in the medieval West, and monastic scribal trends in the late Middle Ages. He has also co-edited three volumes on liturgical studies.
