Dorothy L. Sayers Commenting on G. K. Chesteron

I am reading a biography of Dorothy L. Sayers, Dorothy L. Sayers: A Biography Here is a quote about how Sayers views Chesterton, which uses Chesterton's rather colorful figures of speech.

In later years Dorothy wrote to a young theologian, John Wren-Lewis, that she might well have abandoned Christianity altogether at this time had it not been for the vigorous example of G. K. Chesterton, who saw the history of Christendom as "one whirling adventure...[in which] the heavenly chariot flies thundering through the ages, the dull heresies sprawling and prostrate, the wild truth reeling but erect. (p. 35, Brabazon)
