Robert Oran Miller (February 14, 1935 – June 29, 2009) was an American bishop of the Episcopal Diocese of Alabama from 1988 to 1998.
Between 1967 and 1968 he enrolled in the Anglican studies program at the School of Theology of Sewanee: The University of the South, then a prerequisite for ministers coming into the Episcopal Church from other denominations (he was originally in the Methodist ministry).
He then served as associate minister of First Methodist Church in Anniston, Alabama, from 1963 to 1965, and then as Director of the Wesley Foundation at the Jacksonville State University from 1965 until 1970.
[5] Miller inherited from Stough a strong and vibrant Diocesan infrastructure, along with strong parishes (all congregations in the Alabama diocese are self-supporting, with no "missions" or "vicars" like elsewhere in the Episcopal Church), things that would keep the Diocese of Alabama in good stead as the rest of the Episcopal denomination faced increasingly vicious internecine conflict in the 1990s over matters such as sexual ethics and theology, particularly biblical interpretation.
While the denomination was elsewhere encountering a decided decline in numbers and influence, Alabama kept growing during Miller's episcopate, something that continued well into the 2000s.
