There was no Jewish equivalent of a Magisterium. There were competing Qahals, none of which spoke for all Jews. The closest thing you could say to support your premise is that Jesus replaced a people with a Church, but no Church had existed before it.
"It's really pathetic to see the Catholic church still promulgating the lie that the individual believer is incapable of being led by the Holy Spirit to understand Scripture as Jesus promised we would be."
Please provide me some objective evidence that individual interpretation does not lead to a splintering of Christianity or lead to error because when two denominations disagree on interpretation they both cannot be right. When 30,000+ disagree you have sufficient objective evidence to establish a conclusive proof that is counter to the stated will of God.
Pathetic means having sympathetic sadness and compassion. Your tone suggest anything but sympathy and charity. Disdain, derision, ridicule and condescension are not Fruits of the Holy Spirit. Their predominance in your rebuttals makes whatever point you are attempting as believable and well received as weight loss advice from a 400 lb person over a bucket of chicken and half gallon of Hagen Daas. A more appropriate word than pity would have been schadenfreude.
Peace be with you.
Still trying that tired, old canard, huh? Maybe you didn't read this called, "Unsound Sticks, or, Arguments Catholics Shouldn't Use": http://www.pugiofidei.com/unsound.htm:
This reference lists 8,973 denominations under the heading "Protestant," and 22,146 more under the heading "Independent." Some, but not all, of the "independent" denominations may justly be described as Protestant. Still, these numbers may be inflated similarly to the numbers for Catholics and Orthodox. Suffice it to say that there are thousands of Protestant denominations.
Moreover, even if we could arrive at an accurate tally for Protestant denominations (20,000?), we still could not blame the whole of that number on Sola Scriptura. Some of these churches share substantial unity in faith, even if they are juridically independent (perhaps due to geography). And much of the disunity of faith within Protestantism, at least in the developed world, stems from efforts to subordinate the authority of Scripture (e.g., to various sexual perversions). In reality, if every Protestant denomination were serious and consistent in affirming and applying the rule of Sola Scriptura, the spectrum of Protestant belief would be significantly narrower. It bears emphasizing: the only thing for which we can directly blame Sola Scriptura is the extent to which it fails to provide unity in true faith and morals to those who sincerely adhere to it, e.g., "orthodox" Lutherans, Presbyterians, Baptists, Anglicans, Methodists, Pentecostals, Campbellites, etc.
Though this author is Roman Catholic and biased and it explains his ill-informed view of the unity of the MAJOR doctrines of the Christian faith that DOES exist across many of the mainline Protestant denominations as well as the nondenominational Christians, it is hoped that Catholics who grasp unto this "stick" with which to clobber all those Protestants realize that that same stick hits them on the behind as well.
