The ball and the cross - G K Chesterton

Evan MacIan is a passionate and fiery young Catholic. He is outraged one day by an editorial he reads in 'The Atheist' and vents his anger by smashing the window of the paper's office. He then challenges the editor, Turnbull, to a duel. The feuding men are thwarted at every turn in their attempt to find a suitable place for their fight. While the search goes on they continue their theological debate. They eventually arrive at a position of acceptance and mutual understanding before the story reaches its powerful conclusion.
