Augustine of Hippo
Catena Aurea · Lukasevangelium 8
No man, when he hath lighted a candle, covereth it with a vessel, or putteth it under a bed; but setteth it on a candlestick, that they which enter in may see the light. For nothing is secret, that shall not be made manifest; neither any thing hid, that shall not be known and come abroad. Take heed therefore how ye hear: for whosoever hath, to him shall be given; and whosoever hath not, from him shall be taken even that which he seemeth to have.
(de Quæst. Ev. lib. ii. q. 12.) Or else in these words He typically sets forth the boldness of preaching, that no one should, through fear of fleshly ills, conceal the light of knowledge. For under the names of vessel and bed, he represents the flesh, but of that of lantern, the word, which whosoever keeps hid through fear of the troubles of the flesh, sets the flesh itself before the manifestation of the truth, and by it he as it were covers the word, who fears to preach it. But he places a candle upon a candlestick who so submits his body to the service of God, that the preaching of the truth stands highest in his estimation, the service of the body lowest.
