My talk in the two posts below about being in a trusted position could be very confusing because the situation vary depending on whether the trusted (the clerk in this case),assuming the religiously valid and invalid parts of the job cannot be religiously accepted as inseparable into two jobs, has the choice not to be in that position or not. In both cases justice simply requires giving that legal marriage right thing to its owners even if we assume there is no religiously valid use for it. The difference is that if the clerk believes giving that right by choice is religiously wrong and the condition above apply positively on him then that wrong will be in accepting being in such position without justification while the giving of that right to its owners which causes that wrong will continue to be not only valid but religiously required. 

What is the job requirement of the clerks who issue the marriage licences regarding application of the law and the legal system? Is it to apply the law as they believe it should be or is it to apply the law as it is? Because if it is the later then even if that same sex legal marriage recognition is as wrong as describing a dinosaur as a cat, those who apply for such license have the right for it to be acknowledge as existing in the legal system as it is.
