To the victor go the spoils!It's the opposite actually. Let's see if we can agree on the history of the christian church.
There were many new ideas, as you put it, circulating even while the Apostles were still alive,,,John wrote about the gnostics - or, at least, he referred to them I should say in 1 John 2:19....they went from us because they were not of us.
He was talking about the gnostics.
The heresies circulated for decades and finally it was decided to have councils. At this time the church would officially agree on the doctrines that were to be accepted and followed and those that were to be discarded.
The most famous one of all was Arianism which was handled at the Council of Nicea in 325AD.
The canon of the bible was decided upon at the Council of Carthage in about 390AD.
This is because there were other writings circulating that some were using as if it were scripture and the church (the CC) wanted an official NT bible that every individual church would usse.
For instance, some of these writings included: The Didache, The Shepherd of Hermes and the letters of Ignatius of Antioch who learned from both John and Peter directly.
Scripture was codefied as my above explains.
Trent was in opposition to Protestantism and is an entirely different discourse.
Rome was important because Peter was the bishop of Rome (thus he is called the first "pope" of Rome) and when there was uncertainty as to a teaching, Peter was consulted b ecause he was one of the Apostles.
It was continued.
Read the Early Church Fathers.
What exactly do you believe was not continued??
Christ and his church conquered the pagan Roman Empire!
Dan 2: 44 And in the days of these kings (Roman Caesars) shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
Isaiah 2:2
And it shall come to pass in the last days, that the mountain of the Lord's house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.
Micah 4:1
But in the last days it shall come to pass, that the mountain of the house of the Lord shall be established in the top of the mountains, and it shall be exalted above the hills; and people shall flow unto it.
