vocation originally applied to a religious calling, a word from God. The modern meaning is the equivalent of a job.
It actually derives from the latin words voice and vocatio - which has a much broader context than a religious calling and refers to any kind of summons or calling. So the notion of a vocation has never exclusively referred to a religious calling, and clearly doesn't now as I suspect most of the vocations people will consider will be secular, for example nursing, medicine or teaching.
So, as so often, you fail to understand the broader context, not being able to see beyond your religious blinkers.
Indeed as I have pointed out you call office in the church a job and inflict secular views of management on it.
While apparently seeking some kind of priesthood for yourself
.......it's more than a job ooooooooooooo.
As you have no real idea of academia, then I suggest we all take anything you say about it with a pinch of salt. But, yes it is more than just a job - hence the academic calling (vocation) and the intellectual calling. People devote their lives to their intellectual academic endeavours in the same manner that no doubt some clergy devote their lives to their religious calling. I suspect there are plenty of other clergy who see their role a job too, albeit one with weird hours (a bit like academia - if you knew anything about it you'd know that it isn't uncommon to find academics working and emailing you in the early hours).
