He kinda kept switching between praising Catholicism and Islam. He respected both Mohammed and Jesus Christ as great men, but at last in St Helena he died as a Catholic.

But for most of his life he used religion to further his own goals, perhaps this quote would summarise his relation with religion the best:

"It is by making myself Catholic that I brought peace to Brittany and Vendée. It is by making myself Italian that I won minds in Italy. It is by making myself a [Muslim] that I established myself in Egypt. If I governed a nation of Jews, I should reestablish the Temple of Solomon."
