The Flexibility of a Christian Worldview

I'm reading The Unintended Reformation with the Monday reading group and will probably post about it regularly for the next month or so.  I came across a good point today that I wanted to emphasize:

"Because the central claims of Christianity were not based or dependent on any philosophy but rather on God's putative actions in history, inherited assumptions and practices provided a framework for the testing, debate, and discriminating assimilation of philosophical ideas compatible with the faith" (39-40).

Brad Gregory is talking about the late Middle Ages here and about how Christian thinkers could appropriate elements from Platonism, Aristotelianism, Stoicism, even Epicureanism without also adopting their clearly non-Christian elements.  It is also true that "inherited assumptions and practices" at that time would have included a good deal of Roman Catholic ritual and tradition.  One of the reasons the Anglican church can house such a diversity of belief (from charismatic to evangelical to Anglo-Catholic to Sea of Faith non-literalists) is because they all share the liturgy in common.

All of that is introduction. What I want to jump on is the "because" part.  The central claims of Christianity are based in God's actions in history, not on a philosophical system.  This fact has historically made it possible--and I believe continues to make it possible--for there to be some flexibility in the philosophical framework within which Christian faith is housed.

Are there some basics to a Christian worldview?  Yes, I believe there are.  For example, a Christian worldview believes in a God that literally exists, created the world, and acts in the world.  But the basics are event-focused and a relatively short list.

What this means is that those who talk extensively in terms of biblical or Christian worldview are really doing what Augustine did with Platonism or Thomas did with Aristotelianism or Luther or Calvin or Van Til have done.  They are not presenting the biblical or Christian worldview but presenting a Christian worldview that places the core events into some philosophical framework that is not actually part of the core.
