In closer possession of religious truths than the Pope himself

The reference to the Holy Father was not, actually, very opportune: Carolina was one of those Catholics who consider themselves to be in closer possession of religious truths than the Pope himself; and a few moderate declarations of Pius X, the abolition of some secondary feast days in particular, had already exasperated her."This Pope would do better to mind his own business." Then she began to wonder if she hand't gone too far, crossed herself and muttered a Gloria Patri.
