Hm, haven’t this for a long time. Not sure whether I still have the necessary skills. Lucky they have a Matthias Media(MM) bible study on Galatians, it does help a bit, although I don’t quite agree with the application, it seems that the MM’s first study is about attacking relativism whilst the passage is more the distorted version of gospel. Something that deviated from the gospel, not an entirely a different belief, although in effect it might the case.
I hope I won’t spent too much time on this one..
