I disagree; if you remove creation, you undermine God’s authority over creation and you are left with no sound explanation for the origin of anything.
Interpreting the creation accounts as figurative doesn't remove creation, nor does it undermine God's authority (as far as I can tell?). The processes, mechanisms and timeframes would be figurative, but not the concept that we are literally God's creation. If we look at the book of Job, we see that Job was created by God and also naturally born. A God-guided evolution would be exactly that: each individual was created by God through the means of natural processes. We see God working miracles through Paul in the NT: despite the appearance to bystanders that Paul was performing great miracles on his own whims, we see that God can work through things to make things happen. The concept of evolution would be no different. It wouldn't be a random process as whenever the dice fall God determines the outcome. We see this concept in scripture with the casting of lots to determine God's will.
I don't see how a God-guided evolution interpretation would undermine God's authority. But I am curious why you think that is the case?
