Why would the HCM or its (unspecified) fruits have that effect
? It is not clear how denial of something that can be known only by faith could be caused by a method based on the use of historical & literary arguments. That’s like expecting the scientific analysis of the spectrum of colours to affect aesthetic judgements about a work of art. The judgement that the use of blue in a portrait is brilliantly executed, is not affected by scientific analyses of how the various shades of blue & green & the rest are related.
There may be theological topics which have helped to cause more schisms, errors, & heresies than Christology - but none comes to mind. Why not throw out Christology ? It has had 19 centuries to show its fruits, & many of them have (by your test) been utterly disastrous. Men have been exiled, imprisoned, even killed, for having the wrong Christological belief - how many have suffered any of that for their views on the HCM & allied methods ?
I believe the reason why the Historical-Critical Method has such a deleterious affect on the faithful is a result two main issues.
Who is employing it and then the consequence of the method itself.
HCM removes the faith aspect from scripture study. The student tries to learn to context in which the author lived, how the author of a particular passage grew up, what was the political situation, how did the person employ language and so on. So by learning about the author and the times, we can learn about the motivation for the writing and even about word choice. Or so scholars who favor this method say.
There are some things, however, that are often ignored. Such as the
fact that scripture is inspired by God and the authors were moved by the Holy Spirit to write what they did. This is critical. and it is completely ignored by HCM. Instead HCM scholars busy themselves trying to come up elaborate and sometimes fantastic theories about why scriptures agree and do not contradict. The “Q” gospel is an example of this.
Additionally, miracles are sometimes explained-away as “literary devices” or a misunderstanding about places (e.g. explaining the parting of the Red Sea by claiming they actually crossed a marsh
they named the “Sea of Reeds”. And claimimg that it was the Egyption chariots that got stuck in the mire. It does not explain how the foot soldiers drown or how the Israelites heavily loaded carts did not get stuck but the lighter Chariots did.)
By isolating Holy Scripture from faith and trying to interpret it as some type of historical record, the student can get lost in the details and forget the reason for study to begin with. Or even God’s primary purpose in giving us Holy Scripture.
There is also an undercurrent of “We are smarter than people were then.” attitude the infiltrates all of HCM. This grossly inaccurate premise is not generally helpful either.
We can see how using this method can hide the Glory of God in details. As for the
who I mentioned at the beginning? Well, there are always people who want to deny scripture. By provide mundane explanations to miraculous events, little by little, they tear down scripture and do great harm to the faith of many.
Enemies of the Church
love HCM. Why? It gives them the ability to attack the Church indirectly by giving them a basis for alternate explanations or outright denials that certain events even occurred. And they can do under the guise of “scholarly research”.
I am not saying that HCM is all bad. Not at all. It can help us understand what is really happening at the time and why certain things are important. However, to try to apply it to miraculous events, moments of Divine intervention, and the like, then it is being misapplied. Using HCM as the primary or sole method of Scripture study and exegesis, is a misapplication of it as well.
