Ancient Christians thought of God as an absolute, unchanging essence, based on the thought of the philosopher Plato. This underpins our concepts of the Trinity and even the salvation story of Jesus's death and resurrection. But with the rise in the Middle Ages of nominalism, a new philosophy that emphasizes language over substance, the ancient view of God began to fall apart. Christianity is still struggling to pick up the pieces. Here David Galston, Ecumenical Chaplain at Brock University and author of Embracing the Human Jesus: A Wisdom Path for Contemporary Christianity, describes this problem in more detail. He explores different attempts to save or defend God against the problems presented by modern thinking, and introduces some ideas for moving forward with the historical Jesus.
David Galston presented the above talk during the Once and Future God Session of the "Early Christianity: Heritage or Heresies?" conference, sponsored by the Westar Institute in October 2013. He refers a couple times to the God Seminar: this is a new project by scholars affiliated with Westar that is still in the planning stages. You can also watch a discussion of the future of Christianity from this same session.
