At its core, McGraths work is an attempt to take a logical structure to the deeply rooted mysteries of the bible. His purpose is to draw conclusions regarding the nature of Christian Theology through the application of scientifically derived, systematic logical constructs. Does he succeed? In some ways yes, he does expose the complexities-or contradictory-ideals that have persisted since the dawn of the philosophy. McGrath is very adept at drawing parallels that can cause an individual to question the very nature of Christian Theology.
Ultimately, however, in my opinion, McGrath takes full advantage of his analysis to not simply lay open the main theories of Christianity to be picked at and over analyzed but rather, through analogy makes the supposition and the case-quite persuasively-that Christians think the way they do because of an unrelenting, unwavering trust or “faith” in a divine presence they cannot.
