Romans 8:33 shows that Calvinism and classical theology do not always know the right answer. Bible commentary.
"Who will bring any charge against God’s elect? It is God who justifies." (Romans 8:33, NRSV)
Sarah Ruden, PhD, poet, recent translator of the Confessions of Augustine thinks that Romans 8:33 is not about the notion of “election” (chosen from before the Creation to be saved or to be reprobate) in the Calvinist (or in the wider, classical theistic) sense, but more like this: once people are elected by God to be saved at a point in time, they can rest assured that God's will is stronger than any human attempt to change it. And this idea is wrapped in a rhetoric wordplay of Paul with the Greek words. Beautiful.
