Discussing
15 years after The Office, is there still purpose in selling paper?

Even after a decade and a half, The Office's take on vocation is both relevant and deeply spiritual.

vocation - or as Martin Luther (the original and first Reformer of note) said: the priesthood of all believers. (shame you could only allude to him, "the Reformers", and not give him due credit for espousing this doctrine

Your quote from Smith shows that there is nothing that isn't spiritual. And I think that's true even for those who think nothing is ever spiritual.
