Guido de Graaff – Director of Studies

Guido joined the staff in 2010 as the Director of Studies. He teaches Christian doctrine and ethics.After studying theology in the Netherlands, he moved to Oxford to do a doctorate in Christian Ethics. His research focused on the political significance of friendship, particularly from the perspective of Christian political ethics and theology.

A revised version of his dissertation was published in 2014 under the title Politics in Friendship: A Theological Account (Bloomsbury / T&T Clark).

Guido lives in central London.

“By the time they begin at St Augustine’s, students have already reflected much on their faith and calling, which they continue to do throughout their studies. Teaching theology to people with such a level of commitment is a great privilege.”
