Abstract

The author shows that Aquinas’s treatise on the Trinity can be viewed in two ways. According to the first, now prevailing opinion, the thoughts of the Angelic Doctor are too speculative and in essence they harm our personal relationship with God. He aims to show that the main source of inspiration for this approach are those currents in modern and contemporary philosophy according to which any metaphysics is impossible. Adherents of the other view do not reject metaphysics, and so they are also sympathetic towards Aquinas’s connecting speculation with the Trinity doctrine. They see a great advantage in this connexion, as it allows us to understand more deeply the mysteries of faith and so to demonstrate the uniqueness of the Christian message. The author aims to show that both approaches are justified and one should not be sacrificed for the other. He believes that a philosophical framework allowing the old and the new Trinitarian theologies to coexist is provided by Wittgenstein’s conception of speech games.
