Furthermore, Paul's instruction in the following verses all the way through the rest of the chapter (vv. 3–21) and, really, to the end of the Letter (chapters 13-16), are all about church, specifically the gathered-church. So . . . let's read Romans 12:1–2 as church . . . the church is not to be conformed to this world, but be transformed . . .
The translators who translate "your mind" in v. 2b (by the renewal of your mind) don't help interpretive matters, for there is no "your" in Paul's original text, which allows a different read from the text (". . . but by the renewing of perception, imagination, thinking . . .") with the church as a gathered group sitting in dinning rooms throughout Rome, gathered as church for instruction, worship, and fellowship. Of course individuals need to apply this, but the context is the church, so it is a call to the gathered-church, together: true mark's of the gathered-church are forthcoming in Romans 12:9-21.
