Hilary carried the Nicene fight into the Latin West. Exiled from Gaul to Asia Minor for opposing Arianising politics, he used exile to learn the Greek arguments at their source and translate them into Latin theological categories. His On the Trinity became the first major Latin treatment of Nicene doctrine before Augustine. He matters because Athanasius was not fighting alone in Greek; the West also had to learn how to say why the Son is truly God.
