You don't say "no" to The Church. Especially in seventeenth-century Catholic Spain.
"I, " he said in his disagreeable voice, "am Fray Emilio Bocanegra, president of the Holy Tribunal of the Inquisition."
"With those words, an icy wind seemed to blow across the room. The priest made clear to Diego Alatriste and the Italian, succinctly, menacingly, that he did not need a mask to hide his identity, or come to them like a thief in the night, because the power God had placed in his hands was sufficient to annihilate any enemy of the Holy Mother Church or His Catholic Majesty, the King of all the Spains. That said, while his listeners swallowed nervously, he paused to assess the effect of his words, then continued in the same threatening tone."
"Yours are sinful, mercenary hands, stained with blood like your swords and consciences. But the Omnipotent Heavenly Father writes straight with crooked lines."
--Captain Alatriste, by Arturo Perez-Reverte
(I wonder what just rewards await Fray Bocanegra in heaven...apparently only good ones for his "deeds" according to him.)
