No man, when he has lighted a lamp, puts it in a secret place, neither under a bushel, but on a lampstand, that they who come in may see the light.
All Commentaries on Luke 11:33 Go To Luke 11
Cyril of Alexandria
AD 444
He says that a lamp is always elevated and put on a stand to be of use to those who see. Let us consider the inference that follows from this. Before the coming of our Savior, the father of darkness, Satan, made the world dark and blackened all things with an intellectual gloom. In this state of affairs, the Father gave us the Son to be a lamp to the world, to illumine us with divine light and to rescue us from satanic darkness. Since you blame the lamp because it is not hidden but on the contrary is being set high on a stand and gives its light to those who see, then blame Christ for not wishing to be concealed. On the contrary, he wishes to be seen by all, illuminating those in darkness and shedding on them the light of the true knowledge of God. He did not fulfill his miracles so much in order to be wondered at or to become famous. He did miracles so we might believe that although he is God by nature, yet he became man for our sakes, but without ceasing to be what he was. The holy church is like a lampstand, shining by the doctrine he proclaims. He gives light to the minds of all by filling them with divine knowledge. Commentary on Luke, Homily
