In other words, you don’t want to see how they make saints any more than you want to observe the making of sausage. Consider, for instance, Francis Oakley’s review of a new book on canonization:
During much of the first millennium of Christian history, when it came to the recognition of sanctity, spontaneity seems to have been the order of the day. That is to say, the initiative was usually taken at the popular local level in Christian communities where cults of martyrs, confessors, and other saintly individuals had welled up and found expression in rituals and offerings at the tombs of the deceased or pilgrimages to reputedly holy sites. Official ecclesiastical sanction for such cultic practices was at first no more than sporadic. In the latter part of that era, however, local ordinaries increasingly undertook to exercise at least a supervisory role in relation to such saintly cults. And in a third phase, the one on which Prudlo focuses in this book, the high medieval quickening of papal centralization led to the growing papal domination of the process of saintly canonization, culminating in the fourteenth century with what almost amounted to papal monopolization of the whole business. “Almost” because, as Prudlo prudently concedes, that development may not have been “fully completed” until Urban VIII in 1634 definitively reserved to the papacy the prerogative of canonization.
The church that Jesus founded? Hardly.
The implications of this process for papal infallibility are also intruiguing:
the accumulating discourse pertaining to infallibility in canonization provided a new vocabulary and a new lexicon with which to carry on development of the infallibility discussion into the Counter-Reformation and beyond. It is true that when the First Vatican Council came finally to define the dogma of papal infallibility it made no mention of infallibility in canonization and focused exclusively on the broader issue of ex cathedra papal doctrinal definitions on matters of faith and morals. But recondite though the canonization-infallibility nexus may be, Prudlo’s findings are directly and significantly pertinent to the ongoing debate about the historical origins of the infallibility dogma and any historians working henceforth in that conflicted field will certainly have to take those findings into account.
In other words, papal infallibility is bound up with the debatable practice of recognizing saints.
Notice too that the doctrine of infallibility was originally designed to restrict, not enhance, papal authority:
the doctrine had been advanced with the goal not of enhancing papal power but of limiting it via the insistence that popes were bound by the inerrant, irreformable teachings of their predecessors. It is not surprising, then, that Pope John XXII (1316–34), no theologian but a canonist of distinction, seeing the insistence on papal infallibility as an infringement upon the pope’s sovereignty, described it as a “pestiferous doctrine” and treated it accordingly as some sort of dangerous novelty.
Meanwhile, everyone should have known that if Paul could refer to the Corinthians as saints, such hoops and hurdles were hardly necessary or very sanctified.
