But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus Christ, his Son, cleanses us from all sin.

 (i) Truth is the creator of fellowship. If men are really walking in the light, they have fellowship one with another. No belief can be fully Christian if it separates a man from his fellow-men. No Church can be exclusive and still be the Church of Christ. That which destroys fellowship cannot be true.
