How does the にして work here?

Question

学園付きの聖職者にして、委員会の顧問、xから、呼び出しのメールが来たのは今朝のこと

I read that

adj + にして + adj

or

noun + にして + noun

That in this case the にして has the meaning of "and / also"

In that case does this mean

It was this morning that I received a mail that called me out from X who is the advisor of the committee and the clergy of the school

Answer 1

にして can be used to combine two nouns and it means "and". Unlike "also", it puts the equal weight on both sides. It doesn't work with adjectives, ant it has a pinch of formality in it. It's usually not used in speaking Japanese.
