Most people nowadays do not realize at all how materialistic they are in themselves and their thought. They may be zealous in prayer and confession and have the word "God" for ever on their lips, they may even be priests by calling and conviction, and yet be materialists. Christian morality is, like every morality, renunciation and nothing else. Those who do not feel it to be so are materialists.
-- Oswald Spengler, 1933
So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
-- Luke 14:33
