ABSTRACT
While the doctrine of the Trinity may be said to occupy in Christian doctrine a place analogous to metaphysics in Greek philosophy, this Christian metaphysic (to which the name theologia is often appropriated from the fourth century onwards) differs radically from any Greek system in breaking the link between being and the intelligible. The God who is identified with being transcends the categories associated with the noetic world, and the three persons of hypostases in which his being is manifested are differentiated not ontologically but by skhêsis or relation.
