Christianity is often accused of believing in a "God of the Gaps." What her detractors often accuse the Church of is justifying belief in God by pointing to the "gaps" in human knowledge. Gaps which they - as good children of the enlightenment - know will inevitably be filled in by the March of Human Progress™.
Certainly we know this is a false accusation. Our belief does not rest in gaps, but rather in encounter. As to knowledge, in many ways the more profoundly we understand the natural world, the more profoundly we meet its maker. But I think they may be on to something with this "God in the Gaps" concept.
