Dr Williams is acknowledged internationally as an outstanding theological writer, scholar and teacher. He has been involved in many theological, ecumenical and educational commissions. He has written extensively across a very wide range of related fields of professional study – philosophy, theology (especially early and patristic Christianity), spirituality and religious aesthetics – as evidenced by his bibliography. He has also written throughout his career on moral, ethical and social topics and, since becoming archbishop, has turned his attention increasingly on contemporary cultural and interfaith issues.
As Archbishop of Canterbury his principal responsibilities are however pastoral – leading the life and witness of the Church of England in general and his own diocese in particular by his teaching and oversight, and promoting and guiding the communion of the world-wide Anglican Church by the globally recognized ministry of unity that attaches to the office of bishop of the see of Canterbury.
