I’m afarid that it is the Catholic church that has added additional layers of authority that are not biblical - bishops, arc-bishop, cardinals, etc

Here is a passage from the Didache…if you have not heard this…this is the earliest written form of the teaching of the Apostles.
Chapter 15. Bishops and Deacons; Christian Reproof. Appoint, therefore, for yourselves, bishops and deacons worthy of the Lord, men meek, and not lovers of money, and truthful and proved; for they also render to you the service of prophets and teachers. Therefore do not despise them, for they are your honored ones, together with the prophets and teachers. And reprove one another, not in anger, but in peace, as you have it in the Gospel. But to anyone that acts amiss against another, let no one speak, nor let him hear anything from you until he repents. But your prayers and alms and all your deeds so do, as you have it in the Gospel of our Lord.

And here is another one, from Clement of Rome, a disciple of St. Peter, writing of the instructions he received:
CHAPTER 42 – THE ORDER OF MINISTERS IN THE CHURCH.
The apostles have preached the Gospel to us from the Lord Jesus Christ; Jesus Christ [has done sol from God. Christ therefore was sent forth by God, and the apostles by Christ. Both these appointments, then, were made in an orderly way, according to the will of God. Having therefore received their orders, and being fully assured by the resurrection of our Lord Jesus Christ, and established in the word of God, with full assurance of the Holy Ghost, they went forth proclaiming that the kingdom of God was at hand. And thus preaching through countries and cities, they appointed the first-fruits [of their labours], having first proved them by the Spirit, to be bishops and deacons of those who should afterwards believe. Nor was this any new thing, since indeed many ages before it was written concerning bishops and deacons. For thus says the Scripture a certain place, “I will appoint their bishops s in righteousness, and their deacons in faith.”
CHAPTER 44 – THE ORDINANCES OF THE APOSTLES, THAT THERE MIGHT BE NO CONTENTION RESPECTING THE PRIESTLY OFFICE.
Our apostles also knew, through our Lord Jesus Christ, and there would be strife on account of the office of the episcopate. For this reason, therefore, inasmuch as they had obtained a perfect fore-knowledge of this, they appointed those [ministers] already mentioned, and afterwards gave instructions, that when these should fall asleep, other approved men should succeed them in their ministry.
What you will notice is that this follows the Biblical model of St Paul as recounted in Acts 13.
