Orthodoxy - Softcover

“Because children have abounding vitality, because they are in spirit fierce and free, therefore they want things repeated and unchanged. They always say, "Do it again"; and the grown-up person does it again until he is nearly dead. For grown-up people are not strong enough to exult in monotony. But perhaps God is strong enough to exult in monotony. It is possible that God says every morning, "Do it again" to the sun; and every evening, "Do it again" to the moon. It may not be automatic necessity that makes all daisies alike; it may be that God makes every daisy separately, but has never got tired of making them. It may be that He has the eternal appetite of infancy; for we have sinned and grown old, and our Father is younger than we.”
--- G.K. Chesterton, Orthodoxy

Orthodoxy (1908) is a book by G. K. Chesterton that has become a classic of Christian apologetics. Chesterton considered this book a companion to his other work, Heretics. In the book's preface Chesterton states the purpose is to "attempt an explanation, not of whether the Christian faith can be believed, but of how he personally has come to believe it." In it, Chesterton presents an original view of Christian religion. He sees it as the answer to natural human needs, the "answer to a riddle" in his own words, and not simply as an arbitrary truth received from somewhere outside the boundaries of human experience.

The book was written when Chesterton was an Anglican. He converted to Catholicism 14 years later. The title, Orthodoxy, is meant to avoid such sectarian questions.

Gilbert Keith Chesterton, KC*SG (29 May 1874 – 14 June 1936) better known as G. K. Chesterton, was an English writer, lay theologian, poet, philosopher, dramatist, journalist, orator, literary and art critic, biographer, and Christian apologist. Chesterton is often referred to as the "prince of paradox." Time magazine, in a review of a biography of Chesterton, observed of his writing style: "Whenever possible Chesterton made his points with popular sayings, proverbs, allegories—first carefully turning them inside out."

Chesterton is well known for his fictional priest-detective Father Brown, and for his reasoned apologetics. Even some of those who disagree with him have recognized the wide appeal of such works as Orthodoxy and The Everlasting Man. Chesterton, as a political thinker, cast aspersions on both Progressivism and Conservatism, saying, "The whole modern world has divided itself into Conservatives and Progressives. The business of Progressives is to go on making mistakes. The business of the Conservatives is to prevent the mistakes from being corrected." Chesterton routinely referred to himself as an "orthodox" Christian, and came to identify this position more and more with Catholicism, eventually converting to Roman Catholicism from High Church Anglicanism. George Bernard Shaw, Chesterton's "friendly enemy" according to Time, said of him, "He was a man of colossal genius." Biographers have identified him as a successor to such Victorian authors as Matthew Arnold, Thomas Carlyle, Cardinal John Henry Newman, and John Ruskin.
