Perhaps rephrasing will help. To be sure, tradition has usually affirmed 5-7, but the level of dependency on 5-7 for specific theologies has varied wildly. Just because two different theologians affirm 5-7 doesn’t mean that their respective doctrinal positions have the same degree of dependence on 5-7. For example, there are views of original sin which absolutely require a historical Fall, and there are views of original sin which are not based on a historical Fall at all.
