you see hankarin, i'm genuinely impressed, because you are JUST RIGHT THERE! i mean you're on the absolute verge of "getting it" entirely or you're already there. most people that start with the position you're starting from simply can't, or it would seem.
you could absolutely call "midrash," "the spirit of the law..." except it applies to all scripture, not just law, and it's not the spirit of it , so much as the process of connecting with the spirit of it.
and you're not entirely incorrect either, that one could technically decide "anything goes." i don't think "anything goes," without a god, i believe there is still some kind of morality that says: "some things are wrong." i have to argue that "some things are wrong." is much different than "anything goes."
on the other hand, if- (if!) you have a very black and white or concrete idea of right and wrong already, another person's/church's/religion's version of "some things are wrong." may seem very much like "anything goes to you," but that would be where you and i disagree (hypothetically?) i don't think, i'll say again, i don't think that "anything goes" no matter what you believe.
the issue here is "the spirit of the law" after all, or just "the spirit of the word itself" which is often different than the letter. and midrash is simply being open to that spirit. the problem is, the words are concrete where the spirit has no such restriction. it's not "anything goes," it's "in the spirit" of things.
it's a matter of balance, after all, not falling headlong into concrete restriction nor empty chaos. but the fact remains, one man's midrash may sound overly lenient or even sinful to you. it's up to the person making the connection to be honest with himself, you can't do it for him, but you can reject his interpretation if you think it best. i prefer to learn, when possible. midrash is part of it.
it's "mee drosh" by the way, not quite like the song
but i'll treasure thatas long as i remember it. i'm not talking about changing "one jot or tittle"
of the law, only talking about how it is received, how it is seen. the law doesn't change, god doesn't change, but we can grow closer or farther from meaning. that's all midrash is, it doesn't connotate one direction or the other, that's up to the individual- but it's not concrete at all.
