Is There a Diseased Branch in Atonement Theories?

i really like what new testament scholar joel b green suggests, and and other scholars do as well. But there's not just one theory that can capture the kaleidoscopic picture of atonement that we get in the biblical witness. And so we need to look at it as a whole. The thing that bothers me is that at one point we have to say, are there some diseased branches that need to be cut out? i'm really been thinking and studying and wondering if p s a isn't one of those, you know, diseased branches. I don't know yet.
