"Diversity" is one of the buzzwords of our age, and those of us in higher education have been vigorous in advocating it. The news that St Mary’s University, Twickenham, will be hosting the pontifical faculty which has, since 1614, been awarding pontifical degrees is a sign that diversity really does incorporate a genuine pluralism. The Mater Ecclesiae College, as it will be known, is an outward and visible sign of two things: the vitality of the Catholic faith in these islands; and St Mary’s return to its Catholic roots.
