I don't have Eusebius in front of me but I recall reading that he notes one of the biggest reasons the Epistle to the Hebrews was not universally accepted is because it was not written by Paul. The idea that something was not written by Paul, and then discredited to a degree, was already in place at the time of Eusebius (and we would have to figure earlier).
Well, the issue really isn't so much that it "wasn't written by Paul" but that it wasn't written by an apostle or someone with apostolic connections--indeed, it was anonymous. That was the criteria for determining canonicity: a way to argue apostolicity.
Right, my point was it seems there was already a standard for what was, and what was not, written by Paul. I think modern scholarship thinks itself too original sometimes.
But the standard was not only, "because Paul said he wrote it." There is "The Apocalypse of Paul" that didn't make the cut. Many of the writings that were left out are attributed to apostolic sources. These are the names of the writings Eusebius says are rejected: note the many apostolic names:
Gospel of Peter
Acts of Peter
Preaching of Peter
Revelation of Peter
Acts of Paul
Shepherd of Hermes
2 Clement
Epistle of Barnabas
Teaching of the Apostles
Gospel of Thomas
Gospel of Matthias
Gospel of the Hebrews
Acts of Andrew
Acts of John
There had to be other criteria beyond the writing saying that it was written by an apostle.
There were other criteria, all implicit in the process and never fully and explicitly articulated by anyone in the ancient church. (I discuss these criteria in my book on fundamental theology.) Beyond "apostolicity" (the claim to have been written by an apostle or someone very close to an apostle), they included the antiquity of a document (the older, the better), the catholicity of a document (the more widely used, the better), and the orthodoxy of a document (largely determined by what was considered "orthodox doctrine" taught by the principal patriarchs/bishops [Jerusalem, Antioch, Alexandria, Constantinople, and Rome]). There are seven documents in the NT that ran afoul of one or more of these criteria: Hebrews, James, 2 Peter, 2 John, 3 John, Jude, and Revelation. It is possible that the Pastorals were ultimately included in the canon because they were produced by the person who wrote Luke-Acts, and that individual, though not an apostle, was viewed as being in close proximity to the Apostle Paul. This hypothesis has been discussed among scholars over the past couple of decades.
Peter Ochs' way of bridging the academy and the synagogue is admirable, but it is not the only way to have one foot in each community. Many modern Christian theologians have tried to do the same, starting with Schleiermacher himself and extending into several other "mediating" theologians. Each of the figures treated in the recent books on nineteenth- and twentieth-century Lutheran theologians, in his own way, attempted to do the same, that is, to bridge "Athens" and "Jerusalem."
Addendum: Most, if not all, of the scholars who have judged the Pastorals to have been written by someone after the death of Paul, did their scholarship from within the church and in service to the church. Check the list of names in my earlier post (Jeremias, Dibelius, Kelly, et al.). That is, they, too lived within both communities. Their status as church scholars of the Bible is no different from that of church scholars in the early church. Their judgments should be weighed alongside those of Origen, Jerome, and other ancient scholars. Just as no one individual Bible scholar or bishop in the ancient church spoke on behalf of "the whole church," so no one scholar today (or group of scholars) could ever speak on behalf of "the whole Ecumene." The fact that individual Bible scholars in the ancient church spoke against the seven documents led to their being considered "antilegomena," "spoken against" by one or more Bible scholars in the ancient church. That Bible scholars today, from within the church, speak against the Pauline authorship of the Pastorals, leads to the conclusion that today the Pastorals are also "spoken against."
