“The enduring authority of Christ’s commands should compel Christians to study the Bible’s teaching on the church. Wrong ecclesial teaching and practices obscure the gospel while right ecclesial teaching and practices clarify it. To put it another way, Christian proclamation might make the gospel audible, but Christians living together in local congregations make the gospel visible (see John 13:34–35). The church is the gospel made visible.”
