The odd ones out are the few Christian groups that accept both (a) the dual natures of Jesus Christ, (b) the doctrine of original sin but deny either (c) the immaculate conception or (d) the perpetual virginity of Mary. If you accept both (a) and (b) then either (c) or (d) will defeat the holiness of the mother of God. In the traditional Reformed world, this will get you Calvinists and the like who deny the immaculate conception. In the modern Reformed world, you've got all sorts of groups that reject the perpetual virginity but I have to concede that I don't know how many of these accept the doctrine of original sin.
