Beginning with the wisdom tradition of the Hebrew scriptures, Jesus the Wisdom of God explores what it means to recover the notion that Sophia-Wisdom became incarnate in Jesus of Nazareth, and shows how the universe is altered by this Incarnation. Wisdom Christology then opens out into a view of the trinitarian God at work in ongoing creation. Edwards considers the implications of the trinitarian theology of Richard of St. Victor and St. Bonaventure, centering on the insight that every creature - including humankind - is the free self-expression of the trinitarian God. In this context humanity is revealed as integrally related to all of creation, a part of a single cosmic story. While at one with creation in evolutionary history, humanity is, at the same time, creation come to self-awareness. This train of insights leads to principles for an ecological praxis that affirms human value while insisting that humanity is a part of nature. The whole reinforces commitment to sustainability and a Franciscan attitude of reverence toward God's creation.
