This lecture will introduce some of the principles of the Oxford Movement and the thought of Dr Pusey, John Keble, and the young John Henry Newman. We will see how the doctrine of the Incarnation shaped Pusey’s understanding of the Church, the Bible, and the Sacraments in a radical and controversial way, and how their approach addresses both the spiritual needs and theological questions of the present day. The great mosaics of San Clemente, Rome, and Monreale, will illustrate Pusey’s approach. We will also see how Pusey’s radical Incarnationalism led to radical engagement with the social problems and challenges of his time.
