A plurality of elders provides the flock of Christ with greater pastoral care. In the Old Testament, a multitude of elders were appointed to assist Moses in caring for the people of God. The Lord gave a portion of the Spirit that was on Moses to seventy elders so that they would help carry this burden (Num. 11:16–17). Likewise, in the new covenant church, elders share the responsibility of pastoral care with the minister. Peter writes: “So I exhort the elders . . . shepherd the flock of God that is among you, exercising oversight” (1 Peter 5:1–2). Elders do this in a variety of practical ways.
Living in Milan, I enjoy taking walks around the perimeter of Sforza Castle. Built in the fifteenth century, this structure was one of the largest citadels in Europe for hundreds of years. Its massive walls, more than a hundred feet high, loom over the outer moat like a towering tsunami of brick, making the castle practically impenetrable. There was a time when these walls extended around the entire city, protecting its inhabitants from invasions and providing them with a sense of security. In the medieval world, a city without walls was almost unimaginable. It would have been defenseless and unlikely to survive.
