Had they waited until they saw everything alike, we might not have had our Movement. We have difficulty accepting disagreements among Christians as inevitable. Since the apostles themselves the church has not seen eye to eye on lots of things, some of them rather significant if not essential. It is only a question of how we are going to respond to them. It is love that unites, not doctrinal agreement.
Love perfectly unites that which is divided.
Even if people should reach perfect agreement on all the points of doctrine, this would not mean perfect unity. Only love made for perfect unity, and this when folk may be quite diverse in their interpretation of much of the Bible. Stone and Campbell even differed on the nature of Christ, but they did not allow this to rupture their fellowship in Christ. These standing orders remind us that there is a judge that presides in our hearts, a judge that arbitrates for us in reference to our sisters and brothers. The judge is Peace, and we will capitalize it since it is a presiding judge.
