Translations for confessor in French

Here are paragraphs from public domain books translated:

"PARDIEU! I spoke of them because Porthos talked of them himself, because he had paraded all these fine things before me. But be assured, my dear Monsieur d'Artagnan, that if I had obtained them from any other source, or if they had been confided to me, there exists no confessor more discreet than myself."	— Pardon, interrompit Aramis, j’ai parlé parce que Porthos en parle lui-même, parce qu’il a crié toutes ces belles choses devant moi. Mais croyez bien, mon cher M. d’Artagnan, que si je les tenais d’une autre source ou qu’il me les eût confiées, il n’y aurait pas eu de confesseur plus discret que moi.
