INo protestant churches existed until the 16th century. If I am wrong please prove it.
Do you understand the differences between Christianity as practised in Parthania, and Christianity as practised in Carthage, and Christianity as practised in Antioch, and Christianity as practised in Constantinople?
Also take a look at the Christianity that developed outside the Parthanian and Roman Empires. Pay very close attention to first and second century Christianity in the Near North. What is now known as Mongolia, China, Japan, Vietnam, Korea.
Catholics in the early church, wrongfully thrown out of the CC, leading to schisms? Examples?
The Holy, Roman, Catholic, And Apostolic Church is an example of a schismatic group. Which schism created it, depends upon which heresy you are an adherent of. Pick your date: 310, 359, 688, 1054, 1520. Which flavour of heretical belief and practice do you adhere to? If your heretical beliefs are not reflected in a date given, then substitute the appropriate date.
by whose authority does any one person, (such as myself) - have the right to start a church and call his/her established church the church founded by Jesus Christ on Pentecost?
Treating Christianity as a revealed religion, the issue is whether it was an Oral or Written Revelation. If Oral, then Tradition is crucial, and everything else is an irrelevant distraction. If Written, then only the writings that are Revelatory are crucial, and everything else is an irrelevant distraction. If it was both an Oral and Written Revelation, then both Tradition, and Revelatory Writings are crucial.
The problem with Christianity as Oral Revelation, is that Tradition has strewn it to the winds. That when it spread, the oral teachings, beliefs, practices, and theology were not equally spread.
The problem with Christianity as Written Revelation, is that there is no definitive corpus.
Judaism claims a Written Revelation witnessed by the entire nation. The difference between Karaite Judaism and Rabbinical Judaism, is whether or not an Oral Revelation was Revealed to the nation when Moses handed down the Written Torah.
There is no Written Revelation witnessed by a group of people for Christianity. There is a death on a cross, and a resurrection from the dead. But nothing in writing from the victim of the crucifixion. Well, there are those letters. Letters that are awkward if rejected, but even more awkward if accepted.
