" 14. People should not imagine that just because God and the saints converse amiably with them on many subjects, they will be told their particular faults, for they can come to the knowledge of these through other means. Hence there is no motive for assurance, for we read in the Acts of the Apostles what happened to St. Peter. Though he was a prince of the Church and received immediate instruction from God, he was mistaken about a certain ceremony practiced among the Gentiles. "
