If I tell my boss I will be doing something unless otherwise directed and give him ample time to respond, a lack of response indicates approval of the proposed action. Also, Job 42:11 refers to “the evil God visited upon Job” and throughout the book Satan continually seeks permission to visit more and more woes upon Job, culminating in receiving permission from God to directly effect Job’s health. How then, is “God permitting Satan to tempt” not an indication that God wanted the temptation to occur, thus God’s work?
Given that the majority of my limited scholarly study of Scripture happened while I was at a Wesleyan college, Job is a very old book, predating most of Genesis if I recall correctly (in terms of when it was written by man, not when it happened, though the currency in Job is referred to only in Genesis 33 or by reference - meaning when a different Book recounts part of Job). The Hebrew word for Satan is also rarely used, and is prefixed by an indicator of official title, similar to an agent of a royal court. I’m not an expert on Jewish theology, but my understanding is that the way the Hebrew words for Satan changes throughout the Tanakh may be interpreted as Satan transitioning from an agent of God towards the fallen creature as per current Christian understanding. If the Catholic understanding of when Satan’s fall occurred is definitively pre-Jobian, please let me know - a source for this is greatly appreciated.
