Peter Lampe 
New Testament Theology in a Secular World [PDF ebook] 
A Constructivist Work in Philosophical Epistemology and Christian Apologetics

New Testament Theology in a Secular World is an important and original new work in Christian apologetics. It is the first book to apply constructivist theory to biblical studies. 
Biblical Studies scholar Peter Lampe tackles head on such questions as: What do we understand by ‘reality?’ How does this relate to what theology calls the ‘reality of God’ or the ‘reality of resurrection?’ How can we account for the concept of ’revelation’? Lampe argues that in talking about ‘reality’ theologians must make an effort to engage with the concept of ‘reality’ as it is discussed in the fields of philosophical epistemology and sociology of knowledge. However, as Lampe shows, Theology has so far hardly or only reluctantly participated in this dialogue.
