I'm reminded of an interview question I was asked many years ago. The question was: "if two people come to you and say that their projects are really urgent and I need to drop everything else, what do I do?" My answer "ask my boss" helped get me the job.
The point is that when faced by competing demands, "masters", which do you serve because serving one, responding to one's demands, mean you can't serve/respond to the other. Of course this is an extreme case and often in real life we can juggle requests, but the question was put in a binary way - pick one.
In political terms, if a religious person believes in some scripture but is asked/told be someone else to do something opposite to what the scripture says, what does the person do? Follow scripture or what someone else says? This also applies to atheists with a strong humanistic idea of proper behavior or those who have any sort of moral or ethical framework.
