Disillusioned JW:
Vanderhove7 (and others): In the verse who or what is the household and what is the food?
If " the faithful and wise servant" "is every Christian to whom Jesus will say, “Well done my good and faithful servant!” at his parousia", then who are the servants whom "the faithful and wise servant" has been in put in charge of? Are the other servants (the ones at the receiving end instead of being the ones in charge) also Christians? If not, who are they?
Is the household each congregation of Christians (in the sense of the people who congregated together) or some congregations of Christians (in the sense of the people who congregated together)?
Is the food scriptural statements (such as explanations of scripture) made to people, whether done vocally or in writing? Is it the reading out loud of the scriptures to others? Is the food literal food which is fed to people hungry for literal food to feed their literal tummies?
No. It's a parable. It isn't necessary that each and every element 'means something'. (Especially in Protestant denominations there is a tedious tendency to insist that every little statement in the Bible has some 'greater meaning'.)
Household 'servants' were responsible for preparing meals. The original audience would understand that it is a typical function of the 'servant' in the parable to prepare meals for the household.
Notice also that the admonition in Matthew 24:49 is about beating fellow slaves (i.e. other Christians) rather than denoting any kind of leadership role over any separate hypothetical 'class' of 'domestics'.
