Salt

You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled by men.

St Matthew 5:13

So stay salty!

Salt is good, but if it loses its saltiness, how can you make it salty again? Have salt in yourselves, and be at peace with each other.

- St Mark 9:50

A Salt Cathedral

Via the Creative Minority Report: An amazing Cathedral made of salt.

Just when you think you have seen it all.

New Advent links to a story about an underground cathedral built entirely of salt by devout Polish salt miners.
Simply astounding!!

It may feel like you are in the middle of a Jules Verne adventure as you descend in to the depths of the world. After a one hundred and fifty meter climb down wooden stairs the visitor to the salt mine will see some amazing sites. About the most astounding in terms of its sheer size and audacity is the Chapel of Saint Kinga. The Polish people have for many centuries been devout Catholics and this was more than just a long term hobby to relieve the boredom
of being underground. This was an act of worship.

Amazingly, even the chandeliers are made of salt. An act of worship indeed.
