Gilbert Keith Chesterton - Ecclesiastes

There is one sin: to call a green leaf gray,
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.

Gilbert Keith Chesterton
