"Is not “Christendom” the most colossal attempt at serving God, not by following Christ, as He required, and suffering for the doctrine, but instead of that, by “building the sepulchers of the prophets and garnishing the tombs of the righteous.” ... In comparison with the Christianity of the New Testament, it is playing Christianity. ... Artists in dramatic costumes make their appearance in artistic buildings. ... The teacher is a royal functionary. ... He lectures about renunciation, but he himself is being steadily promoted; he teaches all that about despising worldly titles and rank, but he himself is making a career. ... Christ calls it (O give heed!), He calls it “hypocrisy.” And not only that, but He says (now shudder!), He says that this guilt of hypocrisy is as great, precisely as great a crime as that of killing the prophets. ... This then is the judgment, Christ's judgment upon "Christendom." Shudder; for if you do not, you are implicated in it."
