John 1:10
Knowing therefore this, remove yourselves from the world, and tear yourselves as much as possible from carnal things, for the loss which comes to you from these lies not in common matters, but in what is the chief of goods. For it is not possible for the man who clings strongly to the things of the present life really to lay hold on those in heaven, but he who is earnest about the one must needs lose the other. “You cannot,” He says, “serve God and Mammon”, for you must hold to the one and hate the other.
And this too the very experience of the things proclaims aloud. Those, for instance, who deride the lust of money, are especially the persons who love God as they ought, just as those who respect that sovereignty (of Mammon), are the men who above all others have the slackest love for Him. For the soul when made captive once for all by covetousness, will not easily or readily refuse doing or saying any of the things which anger God, as being the slave of another master, and one who gives all his commands in direct opposition to God.
Return then at length to your sober senses, and rouse yourselves, and calling to mind whose servants we are, let us love His kingdom only; let us weep, let us wail for the times past in which we were servants of Mammon; let us cast off once for all his yoke so intolerable, so heavy, and continue to bear the light and easy yoke of Christ. For He lays no such commands upon us as Mammon does. Mammon bids us be enemies to all men, but Christ, on the contrary, to embrace and to love all.
The one having nailed us to the clay and the brickmaking, (for gold is this,) allows us not even at night to take breath a little; the other releases us from this excessive and insensate care, and bids us gather treasures in heaven, not by injustice towards others, but by our own righteousness. The one after our many toils and sufferings is not able to assist us when we are punished in that place and suffer because of his laws, nay, he increases the flame; the other, though He command us to give but a cup of cold water, never allows us to lose our reward and recompense even for this, but repays us with great abundance.
How then is it not extremest folly to slight a rule so mild, so full of all good things, and to serve a thankless, ungrateful tyrant, and one who neither in this world nor in the world to come is able to help those who obey and give heed to him. Nor is this the only dreadful thing, nor is this only the penalty, that he does not defend them when they are being punished; but that besides this, he, as I before said, surrounds those who obey him with ten thousand evils. For of those who are punished in that place, one may see that the greater part are punished for this cause, that they were slaves to money, that they loved gold, and would not assist those who needed.
That we be not in this case, let us scatter, let us give to the poor, let us deliver our souls from hurtful cares in this world, and from the vengeance, which because of these things is appointed for us in that place. Let us store up righteousness in the heavens. Instead of riches upon earth, let us collect treasures impregnable, treasures which can accompany us on our journey to heaven, which can assist us in our peril, and make the Judge propitious at that hour. Whom may we all have gracious unto us, both now and at that day, and enjoy with much confidence the good things prepared in the heavens for those who love Him as they ought, through the grace and lovingkindness of our Lord Jesus Christ, with whom, to the Father and the Holy Ghost, be glory, now and ever, and world without end.
Amen.
