According to what we read in history and Bible prophecy, Christianity was loosely organized as it spread out from Palestine after Jesus ascended and as persecution steadily increased - this persecution only served to multiply their numbers, because whenever they'd kill one, ten more would join, until finally Satan had enough and changed his tactics - "if you can't beat 'em, join 'em". Constantine legalized Christianity in 323 A.D.
It was then pagan Rome began to embrace the faith with intention to blend Christianity with paganism as a means to "weld" his already crumbling Empire into a strong multi-faith coalition. "Christian" men who formerly cowered in the shadows watching others die for their faith were then all too eager to push their way forward and accept the favor and position and authority now in Rome over the church that the Empire was willing to bestow - and the paganism that was creeping in and defiling the church since the earliest days (Revelation 1-3) began boldly throwing open the doors of the church and marching in right down the center aisle. Many pagan practices were "baptized" into Christianity at this time as the church began to slide into apostasy. But, true Christianity that was spread abroad over the land continued to keep and contend for "the faith once delivered to the saints".
Finally, after the Roman Empire fell around 476 A.D., the ten barbarian tribes who found themselves standing among the ashes of where the great Roman Empire once stood began fighting among themselves, until finally it was agreed that a leader over them all should be appointed. They chose the "Bishop of Rome". In 538 A.D., the "papacy" was established with the pope as supreme ruler of the land over BOTH spiritual AND secular affairs. And the first thing the papacy did was begin an all out assault against Christians everywhere who resisted the paganized form of Christianity that Papal Rome had established. They continued to keep and contend for that same faith that was once delivered to the saints. More cruel than even Emperor Diocletian during his 10 years of most extreme persecution of the church, the papacy systematically sought to wipe out all "heretics" who refused to submit to the will and doctrines of the papacy.
The church then fled into the wilderness (Revelation 12:1-17) to escape the wrath of Satan channeled through Papal Rome against the true followers of Christ. All throughout the land, true Christians lived and worked under constant threat of oppression, persecution, torture, murder, etc. but they continued to strive to fulfill the Great Commission as Jesus had commandment. They were given many names by the papacy to make them seem disconnected and fragmented - names like the Vaudois, the Waldenses, the Albigensis, the Lollards, the Bogemills, the Hugenots, and many, many others - but they were united with bonds of truth's love that could never be broken. Although the papacy sought to present these Christians as just pockets of resistance here and there, the papacy's own archives candidly reveals that the head inquisitors characterized them as an "infestation". A quote from 5th century historian Socrates Scholasticus:
"“For although almost all churches throughout the world celebrate the sacred mysteries on the (7th day) Sabbath of every week, yet the Christians of Alexandria and at Rome, on account of some ancient tradition (THE TRADITION OF WORSHIPING THE SUN ON THE FIRST DAY OF THE WEEK), have ceased to do this.” Socrates Scholasticus, Church History
As the centuries rolled on, the papacy killed many of these "heretics" but it was not until the time of Martin Luther and the Protestant Reformation that the light of the truth began to shine and the church began to emerge from the obscure darkness of its hidden strongholds.
Sadly, over the course of the last 500 years, many Protestant churches have been making one concession after the next to the papacy and today, the papacy officially recognizes "only one consistent Protestant" church - while mocking the rest of the "Protestant" world as proclaiming "Sola Scriptura" by mouth, but holding the authority of the Catholic church over the authority of the Bible by their actions.
