Luke 15:8

(lib. de Virgin. c. 12.) Or else; this I suppose is what our Lord sets before us in the search after the lost piece of silver, that no advantage attaches to us from the external virtues which He calls pieces of silver, although all of them be ours, as long as that one is lacking to the widowed soul, by which in truth it obtains the brightness of the Divine image. Wherefore He first bids us light a candle, that is to say, the divine word which brings hidden things to light, or perhaps the torch of repentance. But in his own house, that is, in himself and his own conscience, must a man seek for the lost piece of silver, that is, the royal image, which is not entirely defaced, but is hid under the dirt, which signifies its corruption of the flesh, and this being diligently wiped away, that is, washed out by a well-spent life, that which was sought for shines forth. Therefore ought she who has found it to rejoice, and to call to partake of her joy the neighbours, (that is, the companion virtues,) reason, desire, and anger, and whatever powers are observed round the soul, which she teaches to rejoice in the Lord. Then concluding the parable, He adds, There is joy in the presence of the angels over one sinner that repenteth.

(non occ.) By the preceding parable, in which the race of mankind was spoken of as a wandering sheep, we were shown to be the creatures of the most high God, who has made us, and not we ourselves, and we are the sheep of his pasture. (Ps. 95:7.) But now is added a second parable, in which the race of man is compared to a piece of silver which was lost, by which he shows that we were made according to the royal likeness and image, that is to say, of the most high God. For the piece of silver is a coin having the impress of the king's image, as it is said, Or what woman having ten pieces of silver, if she lose one, &c.

(de Quæst. Ev. lib. 2. qu. 33.) Or by the nine pieces of silver, as by the ninety and nine sheep, He represents those who trusting in themselves, prefer themselves to sinners returning to salvation. For there is one wanting to nine to make it ten, and to ninety-nine to make it a hundred. To one He assigns all who are reconciled by repentance.

(Hom. 34. in Ev.) He who is signified by the shepherd, is also by the woman. For it is God Himself, God and the wisdom of God, but the Lord has formed the nature of angels and men to know Him, and has created them after His likeness. The woman then had ten pieces of silver, because there are nine orders of angels, but that the number of the elect might be filled up, man the tenth was created. (ut sup.) And because there is an image impressed on the piece of silver, the woman lost the piece of silver when man (who was created after the image of God) by sinning departed from the likeness of his Creator. And this is what is added, If she lose one piece, doth she not light a candle. The woman lighted a candle because the wisdom of God appeared in man. For the candle is a light in an earthen vessel, but the light in an earthen vessel is the Godhead in the flesh. But the candle being lit, it follows, And disturbs (evertit) the house. Because verily no sooner had his Divinity shone forth through the flesh, than all our consciences were appalled. Which word of disturbance differs not from that which is read in other manuscripts, sweeps, (everrit) because the corrupt mind if it be not first overthrown through fear, is not cleansed from its habitual faults. But when the house is broken up, the piece of silver is found, for it follows, And seeks diligently till she find it; for truly when the conscience of man is disturbed, the likeness of the Creator is restored in man.
