2 Corinthians 12:10
If then I shall show [somewhat] which he when alive never dreamed of, neither he, nor any other man that ever lived, what other proof of the resurrection will you require? For that while alive one should win battles and victories, being a king and having armies at his disposal, is nothing marvelous, no, nor startling or novel; but that after a Cross and Tomb one should perform such great things throughout every land and sea, this it is which is most especially replete with such amazement, and proclaims His divine and unutterable Power.
And Alexander indeed after his decease never restored again his kingdom which had been rent in pieces and quite abolished: indeed how was it likely he, dead, should do so? But Christ then most of all set up His after He was dead. And why speak I of Christ? Seeing that He granted to His disciples also, after their deaths, to shine? For, tell me, where is the tomb of Alexander? Show it me and tell me the day on which he died. But of the servants of Christ the very tombs are glorious, seeing they have taken possession of the most loyal city; and their days are well known, making festivals for the world.
And his tomb even his own people know not, but this man's the very barbarians know. And the tombs of the servants of the Crucified are more splendid than the palaces of kings; not for the size and beauty of the buildings, (yet even in this they surpass them,) but, what is far more, in the zeal of those who frequent them. For he that wears the purple himself goes to embrace those tombs, and, laying aside his pride, stands begging the saints to be his advocates with God, and he that has the diadem implores the tent-maker and the fisherman, though dead, to be his patrons.
Will you dare then, tell me, to call the Lord of these dead; whose servants even after their decease are the patrons of the kings of the world? And this one may see take place not in Rome only, but in Constantinople also. For there also Constantine the Great, his son considered he should be honoring with great honor, if he buried him in the porch of the fisherman; and what porters are to kings in their palaces, that kings are at the tomb to fisherman. And these indeed as lords of the place occupy the inside, while the others as though but sojourners and neighbors were glad to have the gate of the porch assigned them; showing by what is done in this world, even to the unbelievers, that in the Resurrection the fisherman will be yet more their superiors.
For if here it is so in the burial [of each], much more will it in the resurrection. And their rank is interchanged; kings assume that of servants and ministers, and subjects the dignity of kings, yea rather a brighter still. And that this is no piece of flattery, the truth itself demonstrates; for by those these have become more illustrious. For far greater reverence is paid to these tombs than to the other royal sepulchres; for there indeed is profound solitude, while here there is an immense concourse.
But if you will compare these tombs with the royal palaces, here again the palm remains with them. For there indeed there are many who keep off, but here many who invite and draw to them rich, poor, men, women, bond, free; there, is much fear; here, pleasure unutterable. 'But,' says one, 'it is a sweet sight to look on a king covered with gold and crowned, and standing by his side, generals, commanders, captains of horse and foot, lieutenants.' Well, but this of ours is so much grander and more awful that that must be judged, compared with it, to be stage scenery and child's play.
For the instant you have stepped across the threshold, at once the place sends up your thoughts to heaven, to the King above, to the army of the Angels, to the lofty throne, to the unapproachable glory. And here indeed He has put in the ruler's power, of his subjects to loose one, and bind another; but the bones of the saints possess no such pitiful and mean authority, but that which is far greater. For they summon demons and put them to the torture, and loose from those bitterest of all bonds, them that are bound.
What is more fearful than this tribunal? Though no one is seen, though no one piles the sides of the demon, yet are there cries, and tearings, lashes, tortures, burning tongues, because the demon cannot endure that marvellous power. And they that once wore bodies, are victorious over bodiless powers; [their] dust and bones and ashes rack those invisible natures. And therefore in truth it is that none would ever travel abroad to see the palaces of kings, but many kings and have often traveled to see this spectacle.
For the Martyries of the saints exhibit outlines and symbols of the judgment to come; in that demons are scourged, men chastened and delivered. Do you see the power of saints, even dead? Do you see the weakness of sinners, even living? Flee then wickedness, that you may have power over such; and pursue virtue with all your might. For if the case be thus here, consider what it will be in the world to come. And as being evermore possessed with this love, lay hold on the life eternal; whereunto may we all attain, through the grace and love towards men of our Lord Jesus Christ, with Whom to the Father together with the Holy Ghost, be glory, might, honor, now and ever, and world without end. Amen.
