Matthew 13:46

"The Kingdom of Heaven is like unto treasure hid in a field, the which when a man hath found, he hideth, and for joy thereof selleth all that he hath, and buyeth that field. Again, the Kingdom of Heaven is like unto a merchant man seeking goodly pearls, who, when he had found one pearl of great price, went and sold all that he had, and bought it." Much as in the other place, the mustard seed and the leaven have but some little difference from each other, so here also these two parables, that of the treasure and that of the pearl. This being of course signified by both, that we ought to value the gospel above all things. And the former indeed, of the leaven and of the mustard seed, was spoken with a view to the power of the gospel, and to its surely prevailing over the world; but these declare its value, and great price. For as it extends itself like mustard seed, and prevails like leaven, so it is precious like a pearl, and affords full abundance like a treasure. We are then to learn not this only, that we ought to strip ourselves of everything else, and cling to the gospel, but also that we are to do so with joy; and when a man is dispossessing himself of his goods, he is to know that the transaction is gain, and not loss. Seest thou how both the gospel is hid in the world, and the good things in the gospel? Except thou sell all, thou buyest not; except thou have such a soul, anxious and inquiring, thou findest not. Two things therefore are requisite, abstinence from worldly matters, and watchfulness. For He saith "One seeking goodly pearls, who when he had found one of great price, sold all and bought it." For the truth is one, and not in many divisions. And much as he that hath the pearl knows indeed himself that he is rich, but others know not, many times, that he is holding it in his hand (for there is no corporeal bulk); just so also with the gospel, they that have hold of it know that they are rich, but the unbelievers, not knowing of this treasure, are in ignorance also of our wealth.

(Quæst. in Matt. q. 13.) Or, A man seeking goodly pearls has found one pearl of great price; that is, he who is seeking good men with whom he may live profitably, finds one alone, Christ Jesus, without sin; or, seeking precepts of life, by aid of which he may dwell righteously among men, finds love of his neighbour, in which one rule, the Apostle says, (Rom. 13:9.) are comprehended all things; or, seeking good thoughts, he finds that Word in which all things are contained, In the beginning was the Word. (John 1:1.) which is lustrous with the light of truth, stedfast with the strength of eternity, and throughout like to itself with the beauty of divinity, and when we have penetrated the shell of the flesh, will be confessed as God. But whichever of these three it may be, or if there be any thing else that can occur to us, that can be signified under the figure of the one precious pearl, its preciousness is the possession of ourselves, who are not free to possess it unless we despise all things that can be possessed in this world. For having sold our possessions, we receive no other return greater than ourselves, (for while we were involved in such things we were not our own,) that we may again give ourselves for that pearl, not because we are of equal value to that, but because we cannot give any thing more.

(Hom. in Ev. xi. 2.) Or by the pearl of price is to be understood the sweetness of the heavenly kingdom, which, he that hath found it, selleth all and buyeth. For he that, as far as is permitted, has had perfect knowledge of the sweetness of the heavenly life, readily leaves all things that he has loved on earth; all that once pleased him among earthly possessions now appears to have lost its beauty, for the splendour of that precious pearl is alone seen in his mind.
