I think this is the relevant basis.
What? Over 1,000 words of Scripture does not tell me what you understand all this to support.
And that this is essential for the conveyance, determination, assurance and preservation of Truth, and with authenticity being assured by historical descent?
There should be an unbroken chain of apostolic succession in the choice of bishops; there must always be a seed that held to the traditional teaching of the Jewish Apostles, guaranteed by the grace and truth of Jesus our Messiah who prophesied the gates of hell would not prevail against the church he built and builds;
So are you answering yes, that an assured infallible magisterium is essential for the conveyance, determination, assurance and preservation of Truth, and that being the historical instruments and stewards of Divine revelation means that such possesses assured infallibility?
Well if you don't like my Scriptures, you probably will not like these verses either, as certain also of your own poets have said
That David played and it pleased the Lord
But you don't really care for music, do you?
O children
Lift up your voice, lift up your voice
Children
Rejoice, rejoice
Hey little train! We're all jumping on
The train that goes to the Kingdom
We're happy, Ma, we're having fun
And the train ain't even left the station
Hey, little train! Wait for me
I once was blind but now I see
Have you left a seat for me
Is that such a stretch of the imagination
Hey little train! Wait for me!
I was held in chains but now I'm free
I'm hanging in there, don't you see
In this process of elimination
Hey little train! We're all jumping on
The train that goes to the Kingdom
We're happy, Ma, we're having fun
It's beyond my wildest expectation
(Somebody say "Play St. Stephen")
Saint Stephen will remain
All he's lost he shall regain
Seashore washed by the suds and the foam
Been here so long he's got to calling it home
Fortune comes a crawlin, Calliope woman
Spinning that curious sense of your own
Can you answer? Yes I can,
but what would be the answer to the answer man?
So are you answering yes, that an assured infallible magisterium is essential for the conveyance, determination, assurance and preservation of Truth, and that being the historical instruments and stewards of Divine revelation means that such possesses assured infallibility?
It sees to me you are articulate, intelligent, with an astute, agile, and facile command of the Scriptures and Biblical languages. If you are wholly convinced the Catholic Church is erroneous, and the Eastern Orthodox as well, why not be an advocate for an Independent Fundamental Baptist remnant that is the direct descendant of genuine apostolic New Testament churches ? And if not, will you in a sentence name which denomination(s) you deem acceptably authentic New Testament churches ? Is there a kosher alternative to publicly confessing Jesus is LORD and Messiah tomorrow in a local Catholic Church (assembly) ?
