Matthew 13:44

This treasure is indeed found without cost; for the Gospel preaching is open to all, but to use and possess the treasure with its field we may not without price, for heavenly riches are not obtained without the loss of this world.

"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.

That he hides it, does not proceed of envy towards others, but as one that treasures up what he would not lose, he hides in his heart that which he prizes above his former possessions. Or, That treasure in which are hid all the treasures of wisdom and knowledge (Col. 2:3.), is either God the Word, who seems hid in Christ's flesh, or the Holy Scriptures, in which are laid up the knowledge of the Saviour.

(Quæst. in Ev. i. 13.) Or, He speaks of the two testaments in the Church, which, when any hath attained to a partial understanding of, he perceives how great things lie hid there, and goeth and selleth all that he hath, and buyeth that; that is, by despising temporal things he purchases to himself peace, that he may be rich in the knowledge of God.

(Hom. in Ev. xi. 1.) Otherwise; The treasure hidden in the field is the desire of heaven; the field in which the treasure is hidden is the discipline of heavenly learning; this, when a man finds, he hides, in order that he may preserve it; for zeal and affections heavenward it is not enough that we protect from evil spirits, if we do not protect from human praises. For in this present life we are in the way which leads to our country, and evil spirits as robbers beset us in our journey. Those therefore who carry their treasure openly, they seek to plunder in the way. When I say this, I do not mean that our neighbours should not see our works, but that in what we do, we should not seek praise from without. The kingdom of heaven is therefore compared to things of earth, that the mind may rise from things familiar to things unknown, and may learn to love the unknown by that which it knows is loved when known. It follows, And for joy thereof he goeth and selleth all that he hath, and buyeth that field. He it is that selleth all he hath and buyeth the field, who, renouncing fleshly delights, tramples upon all his worldly desires in his anxiety for the heavenly discipline.
