“Every member a minister” is not just a slogan. It states a Biblical truth that has shaped the Presbyterian Church from its earliest days. Out of this understanding of ministry as a part of church membership comes the practice of electing and ordaining officers – pastors, elders and deacons – to carry out particular tasks in the life of the church. Elders are set apart, along with pastors, to lead and govern the church. Deacons are set apart for ministries of compassion and service. Pastors are set apart for the ministry of Word and Sacrament.
The existence of these offices in no way diminishes the importance of the commitment of all members to the total ministry of the church.
