Christian theologians assume that systematic theology should make use of the language and methodology of natural science wherever possible to set forth contemporary understanding of Christian doctrine. To this end Joseph Bracken employs the notion of open-ended systems of entities in dynamic interrelation as the basis for an evolutionary understanding of the cosmic process within the natural sciences to give a new more socially oriented understanding of three key beliefs: the incarnation of the Second Person of the Trinity in the God-Man, Jesus of Nazareth; the overall God–world relationship; and Christian eschatology.
