Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 5
Ye are the light of the world. A city that is set on an hill cannot be hid.
Or, men of the world may be figured in the corn-measure as these are empty above, but full beneath, so worldly men are foolish in spiritual things, but wise in earthly things, and therefore like a corn-measure they keep the word of God hid, whenever for any worldly cause he had not dared to proclaim the word openly, and the truth of the faith. The stand for the lamp is the Church which bears the word of life, and all ecclesiastical persons. (vid. Phil. 2:15.)
