Sometimes Luther didn't recognize his own pirated works

When I see Luther paraphrased for this or that cause within the church--global warming, illegal sanctuary, marriage for gays, radical feminism--in such a way and useage we can't even understand the quote or source, it's good to remember it isn't new--it happened in the 16th century, too.

Greed goes to work and plays this mean trick on the publishers of my books: Others quickly reprint the productions soon after their appearance and in this way use the labor and cost of our men for their own profit. . . they pay little attention to the accuracy or the inaccuracy of their reprints. And so it has often happened to me that, reading the text of the reprinters, I have in many places not recognized my own work and have had to revise it anew. They do things in a hit-and-miss manner; their object is money." What Luther Says, vol II, Concordia (1959) p. 848
