In another post, I stated that Dantes thought himself to be the hand of providence. In the case of the book, Edmond feels that he is guided by God.
In chapter 26 "The Inn of Pont du Gard":
"I pledge you my sacred word, madame," said the abbe, "that my intentions are free from all thoughts of harm or injury to you or yours; and that your husband can incur no risk, provided he answers me candidly."
Then later at the begining of chapter 27 "The Tale"...
"First," said Caderousse, "sir, you must make me a promise."
"What is that?" inquired the abbe.
"Why, if you ever make use of the details I am about to give you, that you will never let anyone know that it was I who supplied them, for the persons of whom I am about to talk are rich and powerful, and if they only laid the tips of their fingers on me, I should break to pieces like glass."
"Make yourself easy, my friend," replied the abbe; "I am a priest, and confessions die in my breast... I am an Italian, and not a Frenchman..."
If acting for God, is it possible to lie?
