In Psalm 23, the Lord is described as a shepherd who cares for his sheep completely, leading them to green pastures and still waters (physical care) and restoring their souls and leading in righteous paths (spiritual care).  Being Presbyterian means a church that is led by representative elders and deacons.  Elders, pastors and men elected by the congregation, are responsible for the spiritual care of the members of the church.  Deacons are men from the congregation who have been chosen to lead in the physical care of the church, both people and property.  Together, the elders and deacons represent the full care of Christ who cares for his church in body and soul.
