Or five hundred years in Purgatory.

Martin Luther:

[giving a lecture]
When I became a monk I believed the monk's cowl would make me holy. Was I an arrogant fool? Now they have made me a doctor of divinity and I am tempted to believe that this scholar's robe will make me wise. [laughter] Martin Luther:
Well, God once spoke through the mouth of an ass, and... [laughter] Martin Luther:
Perhaps he is about to do so again. But... [leaves his rostrum and starts walking around in the classroom. The students follow him very interested with their eyes] Martin Luther:
I will tell you straight what I think. Who here has been to Rome? [a student raises his hand] Martin Luther:
Did you buy an indulgence? Student:
No. Martin Luther:
I did. For a silver florin, I freed my grandfather from Purgatory. For twice that I could have sprung grandmother and uncle mothers too, but... [laughter] Martin Luther:
I didn't have the funds, so they had to stay in the hot place. As for myself, the priests assured me that by gazing at sacred relics, I could cut down my time in purgatory. Luckily for me, Rome has enough nails from the holy cross to shoe every horse in Saxony. [laughter] Martin Luther:
But there are relics elsewhere in Christendom. Eighteen out of twelve apostles are buried in Spain. [laughter] Martin Luther:
And yet here in Wittenberg we have the pick on the crown. Bread from the last supper, milk from the virgins breast, a thorn that pierced Christ's brow on calvery and nineteen thousand other bits of sacred bone. [laughter] Martin Luther:
All authentic, ancient, sacred relics. Even Johann Tetzel himself, inquisitor of Poland and Saxony, seller of indulgences extraordinary, connoisseur of relics, envies our collection. [laughter] Martin Luther:
To posses them for a single night he would willingly surrender five years of his earthly life... [laughter, returns to his rostrum] Martin Luther:
Or five hundred years in Purgatory. [laughter]
