Christian Tradition, East and West, has tended to identify Old Testament Wisdom with Christ, on the basis of 1 Corinthians 1:24. There is, however, a minority report from St Irenaeus of Lyons and other early theologians, identifying Wisdom with the Holy Spirit. I re-examine what is ostensibly a less successful early attempt at Trinitarian theology, emphasising the relational, connective role of the Holy Spirit (as the love between the Father and Son). Critiquing strongly substantialist ontologies as a post-lapsarian tendency, I argue via Aquinas' Trinitarian theology of subsistent relations for a dynamic, relational role of the Holy Spirit, uniting God and humanity in the Incarnation. I present this as God's act of creative wisdom which restores the whole cosmos to unity which, like a work of art, is both original and new (cf Ephesians 1, Colossians 1).
