According to Catholicism, does the depositum fidei include the proper interpretation of scriptures about Jesus?

While walking on a road from Jerusalem to Emmaus, two disciples encountered a man whom they later recognized to be the risen Lord Jesus Christ. The Lord Jesus Christ then, "beginning at Moses and all the prophets, he expounded (διηρμήνευεν ) to them the things about himself in all the scriptures."1 Furthermore, the disciples later said that the Lord Jesus Christ "...opened (διήνοιγεν ) to us the scriptures."2 In addition, it is written that the Lord Jesus Christ "opened (διήνοιξεν ) their understanding, so that they would understand the scriptures."3 According to the doctrine of apostolic succession, the Lord Jesus Christ entrusted and delivered the faith (i.e., the *depositum fidei*) to his apostles whom later entrusted and delivered it to their successors, and so forth. Accordingly, if the Lord Jesus Christ opened the understanding of his disciples (students) by thoroughly expouding the scriptures, wouldn't Jesus' disciples have likewise taught their disciples, and so forth? If so, wouldn't the bishops (apostolic successors to the apostles) in the Catholic Church also possess a thorough understanding of the scriptures about the Lord Jesus Christ in the Old Testament? Would that be part of the *depositum fidei*? **Footnotes** 1 Luke 24:27 2 Luke 24:32 3 Luke 24:45
