In the Name of the Father and of the Son and of the Holy Spirit. Amen.
“As presumptuous as it sounds, we Christians are the reason that God preserves the world and does not destroy it right now.” One of my seminary professors once struck at the heart of today's Gospel lesson this way, and it is perhaps a worthwhile entry into Jesus' discourse.
Jesus says to His disciples, “You are the salt of the earth.” Oceans of ink have been spilled onto forests of paper debating what this means. You all know what salt is and what it does. It is one of the most necessary compounds on the planet, right up there with water and oxygen. Salt is one of those things that makes the world go round. Wars have been fought and nations built on the salt of the earth.
But, “if the salt becomes foolishness, in what way will it be made salty?” Salt is a preservative. Aeons ago, salt was practically the only preservative known to man. And it still is the most common way to preserve food throughout the world. And so also you are the salt of the earth. You – the Church – are the preservative of the world.
