Dear Syag,
Please do not misunderstand me. (I did not write out my thoughts well.) I am not trying to push the envelope. Nor am trying to justify those who do. I just think that the difference in what the title is applied to, is similar to the difference in what they actually do. If there was a way to boil it down to algebraic form, [Which I get is wrong. These debates exist, because there is no absolute way to view these things. So I am using what would be a subjective view of objectivity.] It would be something like X*x = Y*x. As far as I could tell, there is no Rebitzzen who is filling the traditional role of a posek.
My point is that pastoral roles are much smaller among groups that are more broad with who can be in that role. For your example, I’m okay with hiring a doctor with a fake medical degree to put band ages on kids.
I admit to not giving a proper understanding of the roles under discussion. Maybe it is totally wrong to give this title to that role. I do not know. And I am not even one bit hinting that it is productive. And I do not believe that it is same role. Just more similar than the labels would indicate.
In sum, I’m walking back my first statement a bit. It was written with more clarity than it deserved.
