The article examines the terms οὐσία and ὑπόστασις, used in the creed formulated at the Council of Nicaea in 325, and their subsequent fate in the history of Christian doctrine on the Trinity. The formulation that finally became established in the Christian East after all the bloody disputes thanks to Cappadocian theology: μία οὐσία, τρεῖς ὑποστάσεις, was also quite difficult to accept in the West. Jerome would have preferred to speak of a single “hypostasis” or “substance” and three “subsistent persons”. Marius Victorinus used esse or “substance” that “subsists” as trifold. Augustine spoke of a single “essence” and “the three” for whom he actually has no suitable designation and only with great hesitation finally accepts the term “persons”.
