So this is another example, to me, of a pastoral correction that has, in it's particulars, more than a little anachronism, which is not a bad thing necessarily. Wesley is imagining a very particular kind of household when he's writing this, one with a Man at the head, his wife and children, perhaps their servants. There are decisions like "should we send the girls to boarding school or hire a governess to teach them at home?" and things of that kind. In short, the kind of household we'd call "upper middle class" today. If I'm trying to peel back the anachronistic advice to the heart of the matter, I think the admonition to those in authority over their households, perhaps even their workplaces, have a duty of 1) excellence in leadership as an example of christ-like leadership and 2) the instruction/coaching of those in their care towards the things of God. That responsibility has it's constraints, which even Wesley acknowledges (you can kick out a visitor, but you must endure your wife), which I think would become more constrained the more professional your context is. The nut of it holds true, though.
