Yes, and that body is manifest in the three churches that derived from the apostles and their appointees, namely the Catholic Church, the Orthodox Church, and the Anglican Church. Churches that had been separated from those three because of time and distance joined either the Catholic or Orthodox churches once communication and transportation was re-established.Protestants contend that the Apostolic Church was the Church of the Apostles. Whatever names adopted the post Apostolic church adopted are the names they adopted. The body of Christ is both visible and invisible, depending upon who is looking.
The mark of the early church was not who had which scriptures but was whether their local churches were part of the "one body", as Paul repeatedly called it, that came from the apostles and their appointees. One can see that process at play in the book of Acts. The Protestant churches simply do not qualify, which is not to say that somehow Protestants cannot be "saved", however.
And it was the Catholic Church under Constantine's order that led to the selection of the canon that you use. Also, there's the issue of church "tradition" since the apostles told their flock to follow the traditions that they set for them as it even shows up in the N.T.
BTW, if you ever see a copy of "Tradition In the Early Church" by Dr. Hanson (Anglican), buy it-- it's worth its weight in gold as it's very informative and heavily documented-- the best I've seen thus far even though it's out of print the last time I checked. Maybe check your local library.
