"They are running still"

Some Chesterton brilliance from "The Everlasting Man":

It came on the world with a wind and rush of running messengers proclaiming that apocalyptic portent, and it is not unduly fanciful to say that they are running still. What puzzles the world, and its wise philosophers and fanciful pagan poets, about the priests and people of the Catholic Church is that they still behave as if they were messengers. A messenger does not dream about what his message might be, or argue about what it probably would be; he delivers it as it is. It is not a theory or a fancy but a fact.... All that is condemned in Catholic tradition, authority, and dogmatism and the refusal to retract and modify, are but the natural human attributes of a man with a message relating to a fact.... The religion of the world, in its right proportions, is not divided into fine shades of mysticism or more or less rational forms of mythology. It is divided by the line between the men who are bringing that message and the men who have not yet heard it, or cannot yet believe it.
