St Augustine, Bishop and Doctor of the Church (354-430 AD), was once walking along the seashore, meditating on the unfathomable mystery of the Holy Trinity.

A boy was using a shell to pour seawater into a little hole.

When Augustine asked him what he was doing, he replied, “I am emptying the sea into this hole.”

Thus did Augustine understand that man would never penetrate to the depths of the mystery of God.
