[Consider these differences:

A versus B:  “Order” versus “Chaos”

A1 versus A2: “Designed Order” versus “Spontaneous Order”

A2A versus A2B: “Spontaneous Order viewed through eyes evolved to see design” versus “Spontaneous Order viewed through the lens of statistics, that is, chance and necessity, devoid of instrumental causes and formal requirements”

What are the options?

To me, Schoonenberg and de Chardin concluded that only the options A1 and A2B could be entertained.  But they bridled at that conclusion.

Suprasovereign Christianity promoted A1. The (infra)sovereign “Believers of Reason” promoted A2B.

My guess is that de Chardin wanted Christians to see that option A2B made sense, hoping that it could be transcended.

My guess is that Schoonenberg would have articulated option A2A if he knew what we know fifty years later.]
