“No one, when he has lit a lamp, puts it in a secret place or under a basket, but on a lampstand, that those who come in may see the light.” Luke 11:33
For a lamp, He says, is always elevated, and put upon a stand, to be of use to those who see. And let us consider the inference which follows from this. Before then the coining of our Saviour, the father of darkness, even Satan, had made the world dark, and blackened all things with an intellectual gloom; but in this state the Father gave us the Son, to be as it were a lamp to the world, to irradiate us with divine light, and rescue us from Satanic darkness. But, O Jew, if you blame the lamp, because it is not hidden, but on the contrary, being set on high on a stand, gives its light to those who see, then blame Christ for not wishing to be concealed, but on the contrary to be seen of all, illuminating those in darkness, and shedding on them the light of the true knowledge of God.
He did not therefore fulfil His miracles so much in order to be wondered at, nor seek by them to become famous, as that we might rather believe, that whereas He is God by nature, yet He became man for our sakes, but without ceasing to be what He was. And upon the holy church as a lamp-stand, shining by the doctrine He proclaims, He gives light to the minds of all by filling them with divine knowledge.
