Eryl Stephen Thomas was a Bishop of Monmouth and a Bishop of Llandaff. An Anglesey man, after education at St John's College, Oxford, Eryl Thomas served curacies in the Diocese of St Asaph before being appointed to a parish in South Wales then as Warden of St Michael's College, Llandaff. He was appointed Dean of Llandaff in 1954., and in this post completed the restoration of the war-damaged cathedral begun under his predecessor Glyn Simon. Stephen Thomas was in many ways a charismatic figure, he was renowned for his pastoral and preaching gifts, but he could also divide opinion. He vigorously exposed an important case of misuse of funds in the Church in Wales, incurring thereby some ill-will, and his sociable manner, coupled with his opposition to the Sunday Closing legislation which closed Welsh public houses on the first day of the week irritated Nonconformist abstentionists. A prominent representative of the Anglo-Catholicschool of theology, he seems however to have avoided the narrowness of outlook of some more conservative Christians and played an important role in Jewish-Christian dialogue in the Cardiff area. There is some suggestion that Thomas was considered as a candidate for episcopal appointments during the 1950s, but was not in the event chosen to head a diocese until 1968 when he was elected and consecrated as Bishop of Monmouth. He was translated to Llandaff in 1970. As bishop of Monmouth he was faced with the problem of redundant rural churches the existence of many of which derived from medieval manorial divisions. He argued unsuccessfully for standard modern Welsh orthography in parish names. He was critical of permissive developments in theatrical writing. In 1975 Thomas was convicted of gross indecency which resulted in a fine, and felt obliged to resign, and he remained outside public ministry for a number of years. Although the content of the case might now be seen as indicating that Thomas was bisexual, he made no public statements concerning his orientation and remained married to and supported by his wife Jean,. His appointment as Assistant Bishop in the diocese of Swansea and Brecon from 1988 saw a return to pastoral and episcopal work in the remaining years of his life.
Politics
Politically Thomas is known to have been on friendly terms with the then British Prime Minister Margaret Thatcher, and a letter, which is in the public domain refers to her gratitude for his encouragement "when times are difficult and criticism is so cruel". It is not clear to what extent his political leanings were towards the Conservative Party, but the content of the letter makes reference to a television interview with Thatcher in an edition of the Thames Television programme "TV Eye" which Thomas had seen. Although Thatcher invites Thomas to "Please write again" it is not known whether any further correspondence survives.
