Or perhaps the Lord calls Himself a light shining to all who inhabit the house, that is, the world, since He is by nature God, but by the dispensation made flesh. And so like the light of the lamp He abides in the vessel of the flesh by means of the soul as the light in the vessel of the lamp by means of the flame. But by the candlestick he describes the Church over which the divine word shines, illuminating the house as it were by the rays of truth. But under the similitude of a vessel or bed he referred to the observance of the law, under which the word will not be contained.
