The Vision of St. Augustine
St. Augustine was walking by the seashore one day contemplating the mystery of the Holy Trinity when he saw a little child running back and forth from the water to a spot on the seashore. The boy was using a shell to carry water from the large ocean and pour it into a small pit that he had made in the sand.
Augustine came up to him and asked him what he was doing.
“I’m going to pour the entire ocean into this hole,” the boy replied.
“What?” said Augustine. “That is impossible, my dear child, the sea is so great and the shell and the hole are so little.”
“That is true,” the boy said. “It would be easier and quicker to draw all the water out of the sea and fit it into this hole than for you to fit the mystery of the Trinity and His Divinity into your little intellect; for the Mystery of the Trinity is greater and larger in comparison with your intelligence than is this vast ocean in comparison with this little hole.”
And then the child vanished.
