From one Successor of Peter, to every-man-his-own-pope. There are as many infallible and varied interpretations of Scripture here as there are non-Catholics.
No Christian or church can claim assured formulaic infallibility, which is what Rome has done, having infallibly declared she is and will be perpetually infallible whenever she speaks in accordance with her infallibly defined (scope and subject-based) formula, which renders her declaration that she is infallible, to be infallible, as well as all else she accordingly declares.
And yet within the parameters of which RCs have great liberty to adopt varied interpretations of Scripture in seeking to support Rome and her traditions, and we have seen many such extrapolations here.
Moreover, while private interpretation is condemned (erroneously invoking 2 Pt. 1:20 as teaching that) due to the fallibility of human reasoning, this is what RC converts must use in deciding to submit to Rome as infallible, and must continue to rely on it in discerning what level a magisterial teaching falls under, and thus what level of submission is required, and to some degree the meaning of such teachings.
Nor did the church begin upon the premise of an office of perpetual assured infallibility as per Rome, but souls came to believe in the light of Scriptural substantiation, in word and in power, (2Cor. 4:2; 6:4-10) and assurance that one has eternal life is provided thereby. (1Jn. 5:13)
While a reasonable man can concur with the advantage of a supreme court to adjudicate issues, to present Rome as being like the apostles is a grievous presumption.
The kingdom is indeed divided, part of that being necessary, but it is what it is, and yet God has worked to rescue multitudes of souls from Rome and institutionalized Protestantism through the historic evangelical gospel of grace, and thus expanded the kingdom of God, even though it is those Rome attacks, not her institutionalized Protestants.
The infallible church's results:
Pope Stephen VI (896–897), who had his predecessor Pope Formosus exhumed, tried, de-fingered, briefly reburied, and thrown in the Tiber.[1]
Pope John XII (955–964), who gave land to a mistress, murdered several people, and was killed by a man who caught him in bed with his wife.
Pope Benedict IX (1032–1044, 1045, 1047–1048), who "sold" the Papacy
Pope Boniface VIII (1294–1303), who is lampooned in Dante's Divine Comedy
Pope Urban VI (1378–1389), who complained that he did not hear enough screaming when Cardinals who had conspired against him were tortured.[2]
Pope Alexander VI (1492–1503), a Borgia, who was guilty of nepotism and whose unattended corpse swelled until it could barely fit in a coffin.[3]
Pope Leo X (1513–1521), a spendthrift member of the Medici family who once spent 1/7 of his predecessors' reserves on a single ceremony[4]
Pope Clement VII (1523–1534), also a Medici, whose power-politicking with France, Spain, and Germany got Rome sacked.
