The Logos of History
We can get so distracted by irrelevant information that's often delivered to us in the guise of objectivity about the beliefs of our supposed brothers and sisters in Christ across the ages.
I was just reading an article by a scholar who demonstrated pretty convincingly that Pelagius didn't hold nearly any of the views Augustine attributed to him—that the latter was probably motivated by the will to power, and so on. The subtext a reader might glean from this would be that we can't know which of our beliefs are anything more than the invented pretexts for power grabs by the powerful in our all too human history.
Everything physical and the whole cosmos in its functions are subservient to the Word and therefore to the story at which the human relationship with the triune God is central. The universe is not too vast or too old; the biblical story is not too simple; the details we're given in Scripture are not too sparse; and your brothers and sisters are not too primitive, violent, or stupid for this to be true.
We should let it be of some comfort to know that all Christians of every time and place, no matter the circumstances they've lived through, and no matter the written record they left for us, have also experienced their sin being revealed to them and the peace of Christ overcoming it.
