G. K. Chesterton once wrote, “Catholic doctrine
and discipline may be walls; but they are the walls of a playground. We might
fancy some children playing on the flat grassy top of some tall island in the
sea. So long as there was a wall round the cliff’s edge they could fling
themselves into every frantic game and make the place the noisiest of
nurseries. But the walls were knocked down, leaving the naked peril of the
precipice. They did not fall over; but when their friends returned to them they
were all huddled in terror in the centre of the island; and their song had
ceased.” Orthodoxy Ch. 9
