The World Without a Magisterium: "An everlasting pile of conundrums."

"It seems strange so many Christians think the Apostles fulfilled their commission by writing the New Testament, leaving behind them no successors, nor any need for successors, with the authority Our Lord had given themselves. It seems strange, for one reason, that it would mean only five of the Twelve had obeyed their Master…
It would seem strange for another reason- that the Church Christ founded would have been a teaching church only for a half-century or so, in all the centuries since merely a library.
Circumstances change and someone must have the authority to apply the teachings to the new circumstances; otherwise they end up as frustrations rather than teachings. Even in the doctrines themselves there are depths which the believing mind can explore, with all the danger of error but all the rich possibilities of development. With every operation of the unstagnant mind of man upon the truth, the question must arise, “What did Christ mean?” So it has proved. There is not a word uttered by Christ which has not met a number of diverse interpretations, some of them intelligent, some immensely attractive, but contradicting each other. How are we to know? It is not enough to have Our Lord’s words; the words themselves can only be a kind of talisman without the meaning. Without a teacher- to tell us, beyond the possibility of error, which of the various meanings is Christ’s- we should have no revelation but only an everlasting pile of conundrums." ~Frank Sheed, "Theology for Beginners"
