The Dogmatization of the Bodily Assumption of Mary and the Appeal to History

If Christianity is the truth, it is not possible that no post-apacolic version of it has ever been correct. Catholicism and Orthodoxy do not believe that the church can undergo this kind of revolution without completely manifesting Christ's mission project in being the light of the world through his church until the end of time. If that is not a criteria of falsification, I don't know what is. Thus, I must conclude that not only is such a scenario not true, but it is also not possible.
