John MacArthur and 1 Peter 2:2

I concluded this post with, "Calvinism, of course, does not stand or fall upon a paraphrase of 1 Peter 2:2. It is able to twist any scripture to its ends, and this one need be no exception. So why not just translate it as it stands, and leave its (mis)interpretation up to the theologians?" and I observed an interesting example of this in a sermon by the late John MacArthur that I heard recently on Christian radio. John was exegeting 1 Peter 2 and read the verse in its entirety. Since his favourite Bible version contains the phrase, "with respect to salvation," he read that part too--but then went on to exegete the verse exactly as he would have had it not been present.
