The impossibility of predicting the future allows us only to indicate
which theological developments seem to be needed. These developments c
oncern our changing perception of the world, which requires a reversal
in our understanding of God's Creation, from its most imperfect begin
nings to its unforeseeable future. The passing of evolution from the b
iological to the human level has opened moral dimensions that must be
explored. Rather than return to the beginnings of the church, theology
needs to try to understand Christian faith within evolution, no reint
erpret the past in the light of the new. In evolution, no final doctri
ne is possible. The necessity for doctrine creates a constant tension
with the necessity of its revision. New truth must be paid for by suff
ering. The need is for a coherent theological vision of Creation, Rede
mption, and God's action in the world. Teilhard's metaphysics of union
may be the key to it. In this view love becomes the central force of
creation, which in Teilhard's view opens into an eternal future in God
: in its final stage, evolution becomes Christogenesis.
