what is Moral Standard???

if you ask me, morality doesn't necessarily come from religion. all that's needed is just plain common sense. if it's effects are beneficial, then it must be good. otherwise, it's not. the holy books you mentioned are just written observations from earlier people. it is found out that it brings about good effects, so eventually, it has become the standard for most religious organizations. you could rely to aesop's fables, brother's grimm, mother goose, the arabian nights, and some common books. you will observe that these books convey a lesson or two. and these MAY be some sources of moral standards.
