Members should never criticize another's opinions. Just assume that each is doing his or her best and that they are the property and responsibility of Christ. Spend all your energy assisting the member you feel is weak. Then you, yourself, will be above criticism. Dedication to congregational peace is the work of maturity, and will be accompanied by great personal tranquility.
Unity is the responsibility of the strong.
If the weak are offered strength, peace and congregational health will result. People of all backgrounds and conditions should find a generous welcome in the assembly. I think you understand. I am thrilled to state this revolutionary idea of spiritual democracy. I know it is God's will.
