The famous Doctor of the Church, Saint Augustine, wrote about many subjects of the Catholic Faith, one of these being the mystery of the Blessed Trinity. One day, St. Augustine was walking along the seashore, while thinking about how he would endeavor to explain and comprehend this mystery of the Faith.

His silent thoughts were suddenly, but gently, interrupted at the sweet sight of a child playing along the same beach. St. Augustine merrily watched the little boy hurry over to the sea with an empty bucket in his hand. The boy then, having filled it with water, carried his heavy burden back up onto the beach and to a hole he had prepared in the sand. The bishop watched as the child emptied his bucket into the small pit. His curiosity turned to surprise when he saw the little one run off again towards the vast waters, his empty bucket in hand. Once again the boy filled it full, only to return to his little hole and pour all the water out. Having stood by and watched several instances of this interesting, but seemingly pointless, game, the Saint at last asked the child what he was doing.

"I am trying to empty the sea into this little hole," was the earnest reply.

Amused, the Saint gently shook his head.

"Then you are trying to do an impossible thing," he said.

"No more impossible," answered the child, in a tone now serious as well as patient, "than for you to understand or explain the mystery of the Blessed Trinity."

And saying these words the boy disappeared.
