"For the gifts and callings of God are irrevocable” (Romans 11:2a, NRSV). Often this text is used (and not entirely improperly) to support doctrine about the permanent nature of spiritual gifts, baptism, and ordination. Once the Spirit has acted, what the Spirit has done cannot be undone, we say. But in context in Romans 11, in the wider context of the whole letter, and, as N.T. Wright argues in his book, Justification, in the context of God’s plan to save the whole world through the promises begun with Abraham and his descendants, something much bigger is at stake. And it calls us, as Christians, to step toward rather than away from persons of other religious who are also Abraham’s descendants.
