Abstract
This essay argues that Newman’s theology of justification is a true via media between Roman Catholicism and Protestantism because of its Trinitarian character. While conceding that Newman misunderstood Luther’s theology of justification, this essay explores Newman’s theology of justification through Christ’s divine indwelling in the Holy Spirit. The Holy Spirit is the formal cause of the soul’s justice, because through the Spirit, both Christ’s alien righteousness and an actual inherent righteousness are brought to the soul.Accordingly, justification is a Trinitarian action of “the two hands of God.”
