A superb, must-read post by Fr. Angelo. To quote:
The Catechism also teaches us that all the baptized participate in the triple office of Christ as priest, prophet and king (783). However, priests, especially bishops who have the fullness of the priesthood and most especially the pope as the Vicar of Christ and Head of the apostolic college, have a mandate to exercise these three offices in a particular way. These offices are the proper functions of the Holy Father and the bishops: the priest sanctifies by offering sacrifice; the prophet teaches by delivering God’s message; and the king governs by shepherding God’s people after the heart of Christ (cf., Jer 3:15).
But I believe there is a different but complimentary distinction that needs to accompany this tripartite distinction of office, and that is the twofold distinction of the Law and the Prophets, roughly corresponding to the dogmatic and pastoral teaching of the pope and the bishops. The Prophetic Office actually encompasses both the teaching of the general principles of the faith (the law/dogma) and its practical application (the prophets/pastorality). The first is protected by the guarantee of infallibility, the second is not. And although clearly pastoral teaching must be subordinated to dogmatic teaching, neither can be dispensed with, and both involve faith, even if in some measure the latter involves human faith.
I think it is particular unhelpful and even “unhealthy” to minimize the legitimate and necessary role of the pope as prophet in the second sense, namely, in the role as Universal Shepherd (Pastor) of the Church. Here I am not criticizing the conscientious objector, or the theologian acting in good faith, and with the urgency and necessity of a well-formed and sincere conscience, when this has to do with non-infallibly taught doctrinal and pastoral teaching that does not seem to be reconcilable with previous magisterial teaching, and when such objections are expressed directly to the magisterium itself. Public dissent from magisterial teaching, on the other hand, causes immediate scandal to the faithful. But the know-it-all zealotry has another deleterious effect: the cultivation of a habit of mind that reduces almost every aspect of faith to a calculation of human judgment. (Read entire post.)
