↑"It seems that Paul creates a new word in 1 Thessalonians 4:9 to celebrate the inauguration of God’s new covenant. He commends these new believers for their sincere love for one another. What is perhaps more astonishing is that he attributes this to the fact that “you yourselves are God-taught (theodidaktoi) to love one another” (4:9). There is no evidence that this word existed in Greek before Paul wrote this letter. He creates this word to mark the astonishing change that salvation in Jesus has brought to these people."
