"Luther: The hellish Satan drives you.
Eliza: Why do you say the hellish satan drives me?
Luther: You are like a magician who conjures gulden into the mouths of silly people, but when they open their mouths they have horse dirt in them.
Eliza: Is it because when they open their mouths they have horse dirt in them that you came to me?
Luther: You run against God with the horns of your pride up in the air and thus plunge into the abyss of hell. Woe unto you, Antichrist!
Eliza: I would appreciate it if you would watch your tongue!
Luther: I was frightened and thought I was dreaming, it was such a thunderclap, such a great horrid fart did you let go here! You certainly pressed with great might to let out such a thunderous fart - it is a wonder that it did not tear your hole and belly apart!
Eliza: Does it bother you that it did not tear my hole and belly apart?
Luther: Is not what I said before true, that you have eaten and drunk yourself full of devils, and so spew vainglorious devils out of your hellish gorge?
Eliza: What do you think?
Luther: You reek of nothing but Lucian, and you breathe out on me the vast drunken folly of Epicurus.
Eliza: Perhaps you could try to be less abusive."
I stopped there.
"User 'lutheran_insults' has exceeded the 'max_questions' resource."
In either case, the absurdity shines through.

And no, the man wasn't a saint (something he said himself).
