Origen
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.
But he who would adapt his lantern to the more perfect disciples of Christ, must persuade us by those things which were spoken of John, for he was a burning and a shining light. (John 5:35.) It becomes not him then who lights the light of reason in his soul to hide it under a bed where men sleep, nor under any vessel, for he who does this provides not for those who enter the house for whom the candle is prepared, but they must set it upon a candlestick, that is, the whole Church.
