Many Christian church bodies in the United States have presidents or bishops that function as administrative heads or public faces of that particular church. But none of these quite matches up to the role of the Roman Catholic Pope—the Bishop of Rome. Does not having a single, strong authority open the door for theological and practical innovations in a church? This has not turned out, in practice, to be the case; single, powerful leaders have not historically been able to protect the church from error. The alternative, however—complete autonomy for all individuals—has also been fruitless. The solution is the Bible’s vision of the Body of Christ. Jesus has poured out his Holy Spirit and gifted his whole church with his Word, and God promises that his Spirit will lead and guide his Church into truth through the careful, communal study of the Bible, guided by trained leaders.
