"Teilhard de Chardin noted over fifty years ago that Christianity is a religion of evolution. The very claim that God becomes something other than God points to change within God. This may surprise us, but from a Christian perspective could God become a human person without change? Could the resurrection of Jesus Christ really bring about new creation without changing the relationship of human life to God? The problem of God “changing” arises when we consider God as unified and hence inert substance – the problem of being. However, scripture states that “God is love” (1Jn. 4:8), and love by its very nature is dynamic and relational. Love is energy and spirit. Change, therefore, cannot be extrinsic to God; rather, if God is love, then God is change."
