1. The "original Christians" were all dead by the early Second Century.
So did they succeed or fail at discipling the Faith to the next generation?
2. There was NO denomination for 300 years....
None of the Apostolic Churches are denominations... The Church at Rome, the Church at Constantinople, the Church at Alexandria, the Church at Ephesis... One Church... Fully and wholly existent in many geographic locations... When disputes arose, Churches withdrew Communion until the issue was resolved, IF it was large enough for that drastic of an action...
Among the Apostolic Churches, the Church(es) of the West has gone farthest from the Church(es) of the East than those Churches of the East with whom we are not in Communion... Yet if you look at the actual practice of the Faith in all of them, it is virtually identical...
not the RCC, not the EOC, not the OOC, not the LDS.
Lumping Apostolic Churches with the LDS destroys honest credibility...
All those denominations CLAIM to have been founded directly and personally by Jesus but it's simply a historical fact that there were no denominations at all for 300 years. The first denomination was established by the Roman Empire for the Roman Empire and Jesus didn't found it.
You might want to consider studying the History of the Church... The Church at Antioch, the Church in Ephesis, the Church in Rome, Church in Lebanon, the Church in Greece, the Church in every geographic location and especially the Church in Jerusalem, IS the Apostolic Church... Jesus ONLY founded the Church in Jerusalem, and yet he founded ALL the Apostolic Churches because of the Obedience of the Apostles to His Commandment that they all GO and DISCIPLE ALL the Nations, remember??
So are all those Churches established by Christ?
Or are they founded by men?
And the answer is YES!
The God-man discipled Godded men to disciple the Nations...
Denominations are OUR creation, PEOPLE formed them - I think wisely, but nonetheless, something BELIEVERS did (not Jesus).
Thank-you for your confession that men and not God founded YOUR DENOMINATION...
Christ Himself founded ours...
3. There was LIKELY the "oral message" (in theology, this is called "the Kyergma") that preceded the verbal inspiration of the abiding WRITTEN words of God (God's inscripturated words) - Scripture (roughly 45-70 AD).
False...
It actually began at the first Pentecost, 33AD, and continues to this day and hour -
The Written is a PART of that Praxis...
Eye witnesses had their verbal testimony - a testimony that died with them. But it is only POSSIBLE to know what this kyergma was if it was written down.
Another False...
All one needs to do is look at and compare what is the SAME in ALL the Apostolic Church practices and Services...
It's absurd for Mormons and others to insist that Jesus taught all kinds of dogmas that were "oral" but we have absoluttely no record of for CENTURIES - nothing to remotely substantiate that.
Another False - See above re Apostolic Witness world-wide... And you keep shooting your integrity in the foot by lumping the witness of the world-wide Apostolic Church with a 19th century American Protestant sect-event...
We DO know what was written and affirmed as the words of God and canonical....
Given Canonicity by the Apostolic Church, indeed - You problem is you refuse to go to that Church to be instructed in what those words mean, which is why the Reformation itself disintegrated into so many additional denominations... And is still disintegrating...
and that is found in 27 books, all in our NT. We have those objective, written, historic WORDS and we know the eye-witnesses affirmed those books and embraced them as authoritative because of the Author.
Yes, you have your self-understood words from our Bible...
We have the Faith Christ discipled to the Apostles...
To the issue: Protestants believe that Jesus is the Savior. Period. Anything that undermines that is to be rejected. Anything that lifts high self rather than the Cross is to be rejected. Anything that makes Jesus just an inspiration or teacher or possibility-maker or door-opener or helper is to be boldly, loudly rejected and repudiated. The devil uses all his strength and cunning to try to make all this as complicated and complex as he can - all to make Jesus small and self big, all to get attention off the Cross and on the mirror, to get people to say "Jesus is the Savior but to be saved YOU gotta........." which is a repudiation of Christianity, the Gospel, the Christ.
Pulling out ear-plugs and closing lips is a good thing for overcoming life-long obsessions...
Hearing is healing...
Talking is prolongation of error...
Saying the same thing over and over and over...
Expecting different results...
And then never ever getting them...
Is a CLUE...
