The Bible and WELS Lutherans teach that the true unity of the church is evident when Christians agree in their confession to the doctrine revealed in Scripture. It is not necessary that all agree in matters of church ritual and organization. The New Testament gives no commands about such matters. Those united in faith and doctrine will express their unity by joining in worship, prayer, and church work. We cannot engage in expressions of unity with those whose confession reveals that error is allowed, taught or defended.
