Origen

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.
