The Ball and the Cross is a novel by G. K. Chesterton. The title refers to a more worldly and rationalist worldview, represented by a ball or sphere, and the cross representing Christianity. The first chapters of the book were serialized from 1905 to 1906 with the completed work published in 1909. The novel's beginning involves debates about rationalism and religion between a Professor Lucifer and a monk named Michael. A part of this section was quoted in Pope John Paul I's Illustrissimi letter to G. K. Chesterton. Much of the rest of the book concerns the dueling, figurative and somewhat more literal, of a Jacobite Catholic named Evan Maclan and an atheist Socialist named James Turnbull. Lynette Hunter has argued that the novel is more sympathetic to Maclan, but does indicate Maclan is also presented as in some ways too extreme.
