It appears to me that you know little about how lecturers tutor and teach at college. No professor in any field or sphere pretends or purports to be an expert in every area of a discipline.
In seminary, there are always various disciplines, OT, NT, church history, languages, pastoral care, preaching, hermeneutics, systematic theology, Pauline epistles, gospels, poetry, wisdom, apocalyptic, evangelism, Confession, Reformation and Renaissance church history, world history, religions, etc etc.
NOONE is an expert on all of it. And no pretends to be. Well except for you.
And this of course is how it is in any other discipline - be it science, medicine, law, economics, business. No one pretends or purports to be an expert on every subject.
I don't.
Nor do I have a desire to pretend to be - and to answer every question you put to me. There are lots of people on this site - who are able to attempt to answer it for you.
Again, glad to have you back. Now stop with the moaning and get with the program.
