Michael, are you suggesting that the
scope and
magnitude of disagreement on doctrine(1) among those submitting to the Catholic Church as their supreme authority is similar to that among those that submit to Scipture(2), reasonably interpreted, as their supreme authority(3)?
- Doctrine that relates to that which is essential to salvation.
- Groups that make a reasonable attempt to properly interpret Scripture (not simply any person without any assistance). This will include the main Protestant denominations, but exclude any fringe groups that make no reasonable attempt to study Scripture.
- In both cases I also exclude from analysis those that make no attempt to be properly informed.
I would have thought that there would be no shame in a Protestant acknowledging that Protestantism produces various, sometimes contradictory, doctrines, but that they believe that it is an unfortunate, but necessary, consequence of what they see as the true Christian faith.
I imagine an objective, non-religious observer would claim that Catholics sacrifice liberty for uniformity and Protestants, uniformity for liberty. If I can admit that the scope a Catholic has for interpreting Scripture is narrower than that of a Protestant, can’t you grant that, by and large, Catholic doctrine is more consistent than that of Protestants?
Protestants have greater scope in interpreting the Bible than do Catholics (although of course, it’s not absolute). Scripture is far more ambiguous and difficult to understand than the Magisterial teachings on, for example, Catholic salvation are. One is clearly going to produce various views whereas the other is going to produce far fewer - in fact, on that which relates to the salvation of Catholics, there can be no reasonable disagreement.
I don’t know why anyone would spend much time on arguing that
sola scriptura could ever come close to the uniformity that an authoritative church is capable of providing. It doesn’t ‘prove’ or ‘disprove’ the legitimacy of Protestant beliefs anyway.
