In essence, the prosperity of the Church hinges on the faithful application of the gospel and the acknowledgment of it as our only hope. This perspective cultivates a vision of Christ's sovereignty that extends over the entire earth. It also naturally leads to the distribution of spiritual gifts among individuals, who then contribute to the church’s mission as a result of this singular focus on Christ and His authority. Both the Old and New Testaments affirm Christ's position as the head of the Church, a role that embodies absolute authority. This understanding is vital because the genuine cohesion and operation of the Church transcend human efforts and capabilities. As individuals, we do not possess the power to enhance or improve Christ's effectiveness. Any attempt to orchestrate success through our own initiatives is ultimately shortsighted. The crux of achieving success within the Church lies in redirecting our focus away from our own importance and allowing God to work through us. In exploring the principles of shepherding found in the Old Testament, we come across the important notion of dual headship, which sheds light on the nature and extent of authority within the church. This idea is also closely linked to the way we understand the second use of the law. Within this framework, Christ is not merely seen as the leader of a congregation; rather, He is recognized as the supreme ruler over the entire earth. I argue that when we create a clear separation between doctrine and practice—often described as two-line theology—we risk undermining the full scope of Christ's sovereignty. By viewing our ecclesiastical structure as a society founded on delegated authority, we may inadvertently lower our ambitions and our vision for what the church can achieve. The foundation of authority in the church is grounded in relationships, and it becomes more robust when there is a shared understanding of doctrinal beliefs. Nevertheless, it is crucial to note that these elements do not constitute the essence of our unity; instead, they act as a fundamental starting point that fosters trust among us. This leads us to a profound question about our unity as the body of Christ: how do we effectively apply the teachings of Scripture in our lives? I assert that the way we put these teachings into practice serves as a true reflection of our theological agreement.
