Paul has three terms that he wrote in 2:5-11 that are found nowhere else in the entire Bible. The three words are “nature” (morphe), “something to grasp” (harpagmon), and “exalted…to the highest place” (hyperpsoo). Now, why would Paul only use these words here when he is actually discussing these same ideas just with a different word choice? The answer is because Paul most likely did not compose these verses. It would be like a pastor today quoting the famous hymn “How Fathers Love Us” which contains many verbs, nouns and pronouns that would most likely never be used elsewhere. Pastors rarely use the term scoffers, ruined, or wretched, and Paul similarly used terms in these 6 verses that appear nowhere else in his writings. This is probably the heaviest argument against whether or not Paul himself wrote them
