Perhaps for you that is how it works. For science, no, this is not how it works. It is not true that in science, almost everything we learn comes from authority. In fact, as I mentioned to you, arguing from authority is considered a logical fallacy. And yet you not only rely on this logical fallacy, but insist that relying on authority is the source of almost every thing we know! Almost everything we know is based on what we obtain through a logical fallacy? I don't think so.
While it is true that attempting to argue from authority is a "logical fallacy," in regard to scholars, this kind of argument is really only a fallacy IF the scholars are, all things considered, wrong about their explanations, data, and/or theories. So, to cite a scholar (and do it correctly) is NOT to commit the fallacy of arguing from authority.
In fact, I found it very interesting that Massimo Pigliucci (2015),
an atheist, had this to say about how Skeptics have a tendency to resort to, and overuse, the defense of citing logical fallacies pertaining to the use of authority, and he says:
Indeed, the more we reflect on the nature of the skeptic (and humanist and atheist) community, the more it seems like there is a great potential to do good, but also quite a bit of confusion and misunderstanding on basic issues [such as the fallacy of arguing from authority] ...
...philosophers consider informal fallacies actually fallacious only once the background has been clearly taken into account, since there are instances where those not only are not actually fallacies but represent pretty decent heuristics that are wise to deploy in order to navigate the world pragmatically. For instance, we all rely on one authority or another to back up our claims, because we don't have the time or skills to verify them. It isn't, therefore, a question of authority per se, but of the quality and reliability of such authority. And it is not at all a bad idea to consider the track record of an individual or organization when evaluating their reliability ... (p. 24)
So, Merle, you may want to be a bit more hesitant in telling others that they are committing the fallacy of "argument from authority" if they cite scholars as "having something valid to say on the subject." What might be better is
for you to demand that those with whom you debate properly quote, cite, and/or explain how scholar X's arguments have a bearing upon whatever issue is being discussed. What we can't do is dismiss our debate opponents simply because they mention that "Scholar X says ..." For instance, I don't dismiss your citation of Robert Price's argument about possible interpolations in 1 Cor. 15 as an "argument from authority"; rather, I may simply not agree with his premises.
In fact, I get very, very tired of people using the Consensus Argument, whether they be Christian or Skeptic... that supposedly a majority of scholars believe "such and such," and that because the majority may believe "such and such," we should automatically take their view seriously simply because most of them do, or that we should maybe assume the rightness of whatever basic idea they propose without then launching into at least a moderate investigation to see what validity the supposed preponderance of scholars ACTUALLY has in saying "such and such" about the issue under debate.
As it goes, we often simply see the tired and outworn practice of people claiming that a majority of scholars says "such and such" without also listing just exactly who these scholar ARE in number and in comparative proportion to a like list of other scholars who disagree. (And to those who think that it isn't practical to always list out scholars when referring to "the majority opinion" all I can say is TOUGH...do the work!!! Lay out your 'list' of scholars, something
like this [link]...OR, don't claim a majority vote!!! OR, just don't claim a majority, period, since truth isn't determined by majority affirmation. Personally, I get sick of the "majority argument.")
So, in all of this, I also agree with Pigliucci that all those who debate these issues of the Christian faith while referring to various authorities, whether they be Skeptic or instead Christian advocates of the Bible, need to be willing to do the further "work" of at least trying to understand the contexts of their supposed authorities, as well as the contexts expressed by the opposition.
As far as the "credibility of witnesses" for the resurrection of Jesus is concerned, I'm not even sure why Christians attempt to lay such a high value on whether or not the writers of the four gospels represent "credible" eye-witnesses in and of themselves. It should be enough that the Gospel writers simply be shown to generally (even if not specifically) carry Coherent Articulations about the existence, person, and nature of Jesus the Messiah, along with the accompanying background content they are attempting to convey to the wider public.
On the other hand, if "credibility" of an eye-witness is all that important to the evaluation of the validity of the Christian faith, I would probably contend that Paul is, more or less, a "credible" eyewitness of Jesus as the Risen Lord, with the supposed interpolations within his letters notwithstanding.
