The Wild Knight and Other Poems/Ecclesiastes

by Gilbert Keith Chesterton

There is one sin: to call a green leaf grey,
  Whereat the sun in heaven shuddereth.
There is one blasphemy: for death to pray,
  For God alone knoweth the praise of death.

There is one creed: 'neath no world-terror's wing
  Apples forget to grow on apple-trees.
There is one thing is needful - everything -
  The rest is vanity of vanities.
