Revelation can be made credible as 'the true' and as 'the good.' But in the Bible and tradition is appears not primarily as a teaching (the true) nor even as man's salvation (the good ) but as the manifestation of the glory of God's love. The remaining chapters unfold theology from this biblical centre: the Glory of God's love is the perspective in which the whole of theology must be seen if it is to be made credible without invoking a criterion established by man.
