Does anyone know of any foreign DL graduate theology degrees in Anglican Studies, either in Great Britain or elsewhere?
Right off hand, I don't know of any British Anglican institution offering coursework-based or modular-based master's degrees by DL. However, institutions like Trinity College in Bristol, Oak Hill Theological College in London, and St. John's College, Nottingham (and a few others) are quite willing to allow students to conduct MPhil research in a largely non-resident capacity. By the way, St. John's, though affiliated with Nottingham University, only makes research degrees available to non-resident students by way of a degree-granting agreement with Open University.
