Resumen:
Gregory of Nyssa's theology is profoundly Christocentric. This article delves into Gregory's understanding of Christ's mediation by analyzing some of his writings. Christ's mediation is a key notion in the distinction between theologia and oikonomia. It also turns out to be essential in Gregory's arguments concerning the Word's divinity and the perfect humanity assumed in the Incarnation. Furthermore, the theology of mediation constitutes a key principle of Gregory's spiritual doctrine and eschatology.
