Bede [Griffiths] was one of the great pioneers in the twentieth century of what can be called interspirituality, the activity and process of exploring other traditions in more than an academic sense. It presupposes an intense personal interest in these other forms of faith and spirituality.
The Fathers of the Church spent the first five centuries absorbing the wisdom of Greece and Rome. This was not a haphazard process but a thoughtful development in which precious resources from these two ancient cultures were incorporated into the Christian tradition and made available to this culture in its theology, canon law, cosmology, and culture.
