Papers presented at the Tenth International Conference on Patristic Studies held in Oxford 1987 (see also Studia Patristica 20, 21, 22 and 23). The successive sets of Studia Patristica contain papers delivered at the International Conferences on Patristic Studies, which meet for a week once every four years in Oxford; they are held under the aegis of the Theology Faculty of the University. Members of these conferences come from all over the world and most offer papers. These range over the whole field, both East and West, from the second century to a section on the Nachleben of the Fathers. The majority are short papers dealing with some small and manageable point; they raise and sometimes resolve questions about the authenticity of documents, dates of events, and such like, and some unveil new texts. The smaller number of longer papers put such matters into context and indicate wider trends. The whole reflects the state of Patristic scholarship and demonstrates the vigour and popularity of the subject.
