Why do we disagree? Ultimately, it comes down to faith. The Christianity Ruse is rejecting is the Christianity of Kierkegaard. Faith demands a leap into the absurd. Reason and evidence backing up the faith commitment would render it inauthentic. Believe without seeing the scars! Hence, for Ruse, given that he thinks this the only authentic Christianity, all attempts to make sense of Christianity are pointless. You are trying to square the circle. Davies is a committed Christian, a Roman Catholic philosopher, and theologian. For him, faith and reason do not clash; they are complementary. Hence, for Davies it is legitimate – demanded – that he bring reason to bear on his faith beliefs, for instance, concerning the Trinity and the Incarnation. In the end, although there is sympathy for the beliefs of the other and much respect, Michael Ruse and Brian Davies are on different tracks, and they do not run in parallel.
