Hilary of Poitiers on true piety

In his book on the Trinity, Hilary of Pictavis (modern Poitiers) has a very telling statement regarding the Patristic understanding of the heart of piety: “in confessione pietas est”—“in confession there is piety” (De Trinitate 10.70). For theologians of the Ancient Church like Hilary, doctrinal confession was essential to true piety.
