This dissertation aims to extend trinitarian theology in the wake of the scientific concept of emergent complexity. Emergence involves the growth of higher-level complex systems that cannot be reduced to their lower-level properties. Most significantly, the perichoresis that unites the Father, Son, and Holy Spirit within the external or economic Trinity will affect the internal or immanent Trinity. Emergent complexity within creation will affect the internal divine life. This dissertation augments Karl Barth’s theological method by explicating our primary revelatory experience in light of this scientific phenomenon.
