And Beren would've been in deep, deep, deep trouble if his ancestors had had
not sworn themselves as vassals to the King of Nargothrond, if his father had
not fulfilled those oaths so spectacularly that Finrod had made a reciprocal
oath of friendship and aid to his vassal's house over and above the obligations
of a feudal lord, and if he had fulfilled that oath by aiding Beren.
You may interpret the bible however your religion obliges you. But
*Tolkien*'s religion regarded oaths as serious responsibilities that shouldn't
be taken lightly, not blasphemies that should never be taken at all, and his
fiction reflects
that.
