Neither. As the article linked to above says says, "The Protestant position, and my position, is that all things necessary for salvation and concerning faith and life are taught in the Bible clearly enough for the ordinary believer to find it there and understand."
Which is patent nonsense.
Yes, all truth is in the Bible, either EXplicitly or IMplicitly,
but it is NOT all “clear,” and St. Peter, speaking by the Holy Ghost, said so verbatim. There are many things which the unstable and the untaught distort (wittingly or unwittingly, it doesn’t have to be deliberate distortion).
Luther, the father of Protestantism, was clearly an unstable man. He would flip flop on his interpretations from one issue of TABLE TALK to the next issue.
How clear is it?
Consider the Eucharist: Luther believed that scripture
teaches (and it does, by the way) the literal Real Presence of Jesus in the consecrated bread and wine.
Calvin, by contrast, taught that Jesus was there but ONLY spiritually, not with his glorified body under the appearances of bread and wine.
Zwingli, who also gleaned his doctrine from the “clear” teaching of scripture, denied any real presence, corporeal or spiritual, of Jesus in the Eucharist at all.
Many Protestants today take Zwingli’s position, that the Lords Supper is purely and ONLY symbolic.
What about Eternal Security? Luther said scripture clearly
did NOT teach it. Calvin said scripture DID teach it. Knox agreed with Calvin, from both of whom come the Presbyterian tradition.
What about baptism? Luther held that scripture clearly teaches baptismal regeneration. Calvin denied that, based on his reading of scripture, but still insisted that baptism was somehow a sacrament. For a long time, Luther denied that James, Jude, 2nd Peter, and Revelation were even PART of inspired scripture. Later on, he reversed himself and even wrote commentaries on some of the books he at first and for some time had rejected.
Scripture is not perspicuous. It is difficult. The reformers came along, yelling “Sola Scriptura” and at the same time jettisoning based on whim many of the church’s historic doctrines which are sometimes IMplicit in scripture, not EXplicit. Thus jettisoning the doctrinal tradition of the previous 1500 years, they came up with seriously conflicting theologies which resulted in the multi - denominationalism we see today.
