The fact is that by the time of Ignatius, which was shortly after the writing of the last NT book, not nearly enough time had passed for the development to take place which you imagine. That took another 75 years.
Again not quite. For the first point notice Ignatius doesn't use Bishop and Presbyter interchangeably in his letter to the Smyrnaeans. For the second point we see in his letter a distinction between the two offices.
I greet the Bishop, so worthy of God, and the worthy council of presbyters, and my fellow servants, the deacons, and all of you individually and collectively. - Ignatius letter to the Smyrenaeans 12
Clearly the development I mentioned didn't have to wait another 75 years as you put it.
And what do you mean, "Even in the NT deacon wasn't the same as Bishop or Presbyter."
Maybe I misunderstood you but you seem to say there was no distinction between Bishop, presbyter, and deacon.
In the NT, deacon was never the same as Bishop or Presbyter; deacon was a separate office, one of the only two offices, with bishop/presbyter/overseer/elder/pastor being the other one, these being synonymous terms for one and the same office.
I agree the deaconate was not the same as the Bishop or the presbyters. However, it is clear by the time of Ignatius the churches had grown to the extent where the Bishop's role became distinct from the Presbyter's.
And Ignatius was not using the term "catholic" to refer to the institution
I think you have institution on the brain. Note, not once did I mention "institution". I simply said that Ignatius meant Catholic in the sense of Universal or Universal belief. And it was these same Catholics which when the schism occurred maintained the name Catholic but the word Roman became applied to distinguish between the East and West for the most part. And when modern Catholics read Ignatius they understand him to mean universal.
that became the church of which you are now a part. That is reading back something into his writings and ideas which was not there
Unfortunately, for you, I'm not reading Roman Catholic back into Ignatius writing. I read Catholic meaning universal. It was a time long before the schism separating east and west and additional monikers were not necessary to identify the two groups. But that still doesn't change the fact that Catholics never ceased to call themselves Catholics.
because it also had not developed into what you want to make it. The catholic church of the early church fathers was not the institution that developed later.
As can be seen in Ignatius writings the Church of his day shortly after the Apostles was different than how it was in Acts. The church developed some. As I have shown you with the development with the role regarding the bishops.
It was simply the universal church, or the community of orthodox churches, not what became the Catholic institution.
Well yes to the first part and it did become the modern Catholic and Orthodox churches.
