Editing Karl Rahner (section)

===Economic and immanent Trinity===
Among the most important of his essays was ''The Trinity'', in which he argues that "the economic [[Trinity]] is the [[Immanence|immanent]] Trinity, and the immanent Trinity is the economic Trinity" (sometimes called 'Rahner's rule'). That is to say, God communicates Himself to humanity ("economic" Trinity) as He really is in the divine Life ("immanent" Trinity).

Rahner was emphatic that the identity between "economic" Trinity and "immanent" Trinity does not lead to [[Modalism]], because God could not communicate Himself to humanity as threefold ({{langx|de|dreifaltig|label=none}}) unless He were threefold in reality. Nonetheless, some theologians and Christian philosophers (e.g., [[Jürgen Moltmann]]) have found his teaching to tend strongly in a Modalist direction.{{sfn|Moltmann|1993|p=144}}
