The work of the previous chapters has been to consider how the findings of evolutionary biology fit with key commitments of traditional Christology. Thus far, we think the findings fit quite well. In this final chapter, we widen our scope all the way, asking not whether this finding of biology is problematic for that claim of Christianity but instead asking how biology and its total set of data fit with a Christian worldview compared to a naturalist worldview. Our main concern, then, will be to evaluate Christianity and naturalism in terms of their respective worldview explanations of the very existence of the biological world and the phenomena within it.
