Here is the situation
Person one is given a place to live by person two who owns the home. Person two has a strict diet. Person one eats a varied diet. Person two one day says "If you want to live here, you can no longer put foods that tempt me in the kitchen."
Person one obliges for a time. Time passes and person two of his own volition begins bringing the very foods he told person one not to bring.
Person two sees hypocrisy and resolves to keep his varied diet on hand in the kitchen again, seeing that person two is not abiding by his own rule.
Person two nevertheless insists person one abide by it, and say "If you don't like it find somewhere else to live."
I realize person two is the owner of the home, but eschatologically speaking, does person two have a moral right to make such a demand on those specific terms?
Does person one have a moral obligation to obey person two's hypocritical demand?
Citations from Scripture, the Fathers and especially St. Thomas would be appreciated.
