Gregory the Dialogist

Behold, he who clings to earthly substance more than is right refuses to come to the Lord's supper; he who sweats at the labor of curiosity disdains the prepared nourishments of life; he who serves carnal desires rejects the feasts of the spiritual banquet. Therefore, because the proud refuse to come, the poor are chosen. Why is this? Because, according to Paul's words, God chooses the weak things of the world to confound the strong. But it must be noted how those who are called to the supper and come are described: the poor and the feeble. They are called poor and feeble who in their own judgment are weak in their own eyes. For there are poor who are as if strong, who even when placed in poverty are proud. The blind, indeed, are those who have no light of understanding. The lame also are those who do not have right steps in their conduct. But since vices of character are signified in the weakness of the limbs, it is certainly clear that just as those were sinners who when called refused to come, so also these are sinners who are invited and come. But proud sinners are rejected, so that humble sinners may be chosen.

For this reason the Apostle Paul says: "The time is short: it remains that those who have wives be as though not having them, those who weep as though not weeping, and those who rejoice as though not rejoicing, and those who buy as though not possessing, and those who use this world as though not using it; for the form of this world is passing away." For he has a wife, but as though not having one, who knows how to pay the debts of the flesh in such a way that he is not compelled through her to cling to the world with his whole mind. For when the same excellent preacher says again: "He who has a wife thinks about the things of this world, how he may please his wife," that man has a wife as though not having one who strives to please his spouse in such a way that he nevertheless does not displease his Creator. He also weeps, but as though not weeping, who is so afflicted by temporal losses that he nevertheless always consoles his soul with thoughts of eternal gains. But he rejoices, yet as though not rejoicing, who is so gladdened by temporal goods that he nevertheless always considers the everlasting torments; and in that by which he lifts up his mind with joy, he immediately presses it down with the weight of prudent fear. Moreover, he buys, but as though not possessing, who both prepares earthly things for use, and yet with careful thought foresees that he will soon leave these behind. He also uses the world, but as though not using it, who both outwardly applies all necessary things to the service of his life, and yet does not allow these same things to dominate his mind, so that they serve as subjects externally, and never break the intention of a soul striving toward higher things. Whoever therefore are such, for them indeed all earthly things are present not for desire but for use, because they make use of necessary things indeed, but desire to have nothing with sin. From these very possessions they daily acquire rewards, and they rejoice more in good work than in good possession.
