That old man that you brushed aside? The one you called a liberal and a wishy-washy Christian? He spent the last fifty years with his hands and his heart in the pages of that sacred book. He has wept over it and searched for truth in its stories. His unanswered questions have increased every year until finally he knows nothing at all but the love of God and neighbor.
He knows something that you do not know.
This can be translated into Catholic experience by replacing "the Bible" with "Scripture and Tradition."
There are reactions to guard against when you read essays like this: "He's certainly not talking about me." "My, someone's awfully full of himself." "That's very sweet, but in the real world, we have to be realistic." "Preach it, brother! Lay it on them!" (This last is a particularly subtle way of not listening.)
Reactions to foster? "Is it true?" "Is it true of me?"
