Matthew 13:44

The foregoing parables of the leaven, and the grain of mustard-seed, are referred to the power of the Gospel preaching, which has subdued the whole world; in order to shew its value and splendour, He now puts forth parables concerning a pearl and a treasure, saying, "The kingdom of heaven is like unto treasure hid in a field." For the Gospel preaching is hidden in this world; and if, you do not sell your all you will not purchase it; and this you ought to do with joy. Wherefore it follows, "which when a man hath found, he hideth it."

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.

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.

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. [margin note: Col 2:3]

Or, That treasure "in which are hid all the treasures of wisdom and knowledge," 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.

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.

1. If any one, therefore, reads the Scriptures with attention, he will find in them an account of Christ, and a foreshadowing of the new calling ( vocationis ). For Christ is the treasure which was hid in the field, that is, in this world (for “the field is the world”); but the treasure hid in the Scriptures is Christ, since He was pointed out by means of types and parables. Hence His human nature could not be understood, prior to the consummation of those things which had been predicted, that is, the advent of Christ. And therefore it was said to Daniel the prophet: “Shut up the words, and seal the book even to the time of consummation, until many learn, and knowledge be completed. …

If now anyone demand of us clear and distinct declarations on these points out of holy Scripture, we must answer that it was the design of the Holy Spirit, in those portions which appear to relate the history of events, rather to cover and conceal the meaning: in those passages, e.g., where they are said to go down into Egypt, or to be carried captive to Baby­lonia, or when in these very countries some are said to be brought to excessive humiliation, and to be placed under bondage to their masters; while others, again, in these very countries of their captivity, were held in honour and esteem, so as to occupy positions of rank and power, and were appointed to the gov­ernment of provinces; all which things, as we have said, are kept hidden and covered in the narratives of holy Scripture, because “the kingdom of heaven is like a treasure hid in a field; which when a man findeth, he hideth …

23. And perhaps as those here, dying according to the death common to all, are, in consequence of the deeds done here, so arranged as to obtain different places according to the proportion of their sins, if they should be deemed worthy of the place called Hades; so those there dying, so to speak, descend into this Hades, being judged deserving of different abodes, better or worse, throughout all this space of earth, and (of being de­scended) from parents of different kinds, so that an Israelite may sometimes fall among Scythians, and an Egyptian de­scend into Judea. And yet the Saviour came to gather together the lost sheep of the house of Israel; but many of the Isra­elites not having yielded to His teaching, those from the Gentiles were called.…And these points, as we suppose, have been concealed in the histories. …

“ Again the kingdom of heaven is like unto a treasure hidden in the field, which a man found and hid. ” The former parables He spoke to the multitudes; but this and the two which follow it, which are not parables but similitudes in relation to the kingdom of heaven, He seems to have spoken to the disciples when in the house. In regard to this and the next two, let him who “gives heed to reading” inquire whether they are parables at all. In the case of the latter the Scripture does not hesitate to attach in each case the name of parable; but in the present case it has not done so; and that naturally. …

[1.] God will not have us listen to the words and sentences contained in the Scriptures carelessly, but with much attention. This is why the blessed David hath prefixed in many places to his Psalms the title “for understanding,” and hath said, “Open Thou mine eyes, that I may behold wondrous things out of Thy Law.” ( Ps. xxxii. 42, &c.; Ps. cxix. 18 .) And after him his son again shows that we ought to “seek out wisdom as silver, and to make merchandise of her rather than of gold.” ( Prov. ii. 4 and iii. 14 [partially quoted]; John v. 39 .) And the Lord when He exhorts the Jews to “search the Scriptures,” the more urges us to the enquiry, for He would not thus have spoken if it were possible to comprehend them immediately at the first reading. …

8. “If thou wilt be perfect,” the Lord says, “go and sell that thou hast and give to the poor.…and come and follow me.” If thou wilt be perfect. Great enterprises are always left to the free choice of those who hear of them. Thus the apostle refrains from making virginity a positive duty, because the Lord in speaking of eunuchs who had made themselves such for the kingdom of heaven’s sake finally said: “He that is able to receive it, let him receive it.” For, to quote the apostle, “it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.” If thou wilt be perfect. There is no compulsion laid upon you: if you are to win the prize it must be by the exercise of your own free will. …

Let us diligently ask for mercy, that we may receive whatsoever is necessary for us. Let us seek His Kingdom and His righteousness, that we may receive increase in the land. Let us think upon the things which are above, on the heavenly things, and meditate on them, where Christ has been lifted up and exalted. But let us forsake the world which is not ours, that we may arrive at the place to which we have been invited. Let us raise up our eyes on high, that we may see the splendour which shall be revealed. Let us lift up our wings as eagles, that we may see the body there where it is. Let us prepare as offerings for the King desirable fruits, fasting and prayer. Let us guard His pledge in purity, that He may trust us over all His treasury. For whosoever deals falsely with His pledge, they suffer him not to enter into the treasure-house. …
