Augustine and Karl Rahner on the Relationship between the Immanent Trinity and the Economic Trinity

  Karl Rahner developed his influential axiom concerning the identity of the immanent Trinity and the economic Trinity largely as a polemical reaction to their separation in the Western tradition, a tradition heavily shaped by Augustine. An analysis of Augustine's De Trinitate , however, reveals that Augustine was not guilty of most of the charges of which Rahner accuses him. Furthermore, Rahner's outworking of his fundamental axiom leads him into numerous difficulties that he could have avoided had he adhered to Augustine's view of a close but differentiated relationship between the immanent Trinity and the economic Trinity.
