The present debate that is going on at the frontiers about the nature of theology has for most people yet to be distilled and passed on. There is a severe and crucial change taking place that has been given a noticeable liberation through the climate of dialogue created by the Second Vatican Council.

Indeed the very life of theology itself depends upon this extension to the creative centres of contemporary culture, with a response to the fully historical situation. Furthermore, theology requires to be done by laymen, contributing to it in their capacity as expert witnesses. The experience of adult members of the Church working in specific situations needs to be seen as the raw material of creative theology, and Christian and non-Christian experience will be at once equally valid and applicable.
