Was Athanasius a Trinitarian?

In his recent book on the Arian Controversy (Nicaea and its legacy, 2004), Ayres refers to “Athanasius' own strongly unitarian account” (Ayres, p. 435). He says: > “Studer’s account here follows the increasingly prominent > scholarly position that Athanasius’ theology offers a strongly > unitarian Trinitarian theology whose account of personal > differentiation is underdeveloped” (Ayres, p. 238).
