If scripture was self interpreting, or if the Holy Spirit correctly guides each individual believer to understand the correct interpretation of scripture, we wouldn't have tens of thousands of competing christian sects, each contradicting the other.
No, Yopios simply doesn't work; sola scriptura ain't scriptural.
. 2Tim 3:16,17 16 "All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 17 that the man of God may be complete, thoroughly equipped for every good work."
Christ built a church you say? Define that. Is it only found in Rome (under Romanist authority)?
There were no Romanists in the beginning. The story lines pretending that was factual are a pack of lies, hence the need for "development" or the theory of "unpacking".
As far as singular papacy goes...that took many centuries to "unpack". In 1054 the final press to enact that "development" left the rest of the church not knowing quite how to respond...
Which would leave any honest man, if supporting that idea (of singular "papacy") by default needing also to maintain a position which goes far beyond merely suggesting that ALL of "the church" got it wrong on that score, until the Latin church all on their lonesome discovered that not only should there be a singular personage over all, and a singular portion of the church over and above all others --- but that they themselves should be it!
Talk about Yopios and point fingers at everyone else all you wish, but go back and correct the various Romanist "Yopios" and then we can talk. Until then --- unless there be some personal testimony which may be shared, then I won't hear it, for it is not "the true church" which is talking, but something else instead...
