The cursus honorum proposed in this passage seems strange for several reasons. The reference to the "guardian of the martyrs", as the special clerical grade established for the cult of the saints is unique. On the other side, the grade of ostiarius is not mentioned here. The lengths of various offices are incomprehensible, in particular the thirty years of being a lector and thirty days - an exorcist. The sum adds to an improbable sixty years of ecclesiastical service before becoming a bishop. We know from the Liber Pontificalis itself, that at least at Rome deacons tended to be elected as bishops much more frequently than presbyters, both in the fourth and the sixth century (when John II was the only presbyter to become a pope).
There are some differences in the first edition, the most important is the addition of the lay faithful as the possible source of opposition to someone's ordination: "nullum omnino clerico vel fidele in contra dicentem" (Duchesne 1886: 76).
