The congregation, under the direction of Scripture, is the final authority in our church life. When Jesus and Paul appealed to the authority of the congregation in matters of discipline, they were showing that ultimate authority in a body of regenerate believers rests with the entire congregation. We are a self-governing church, captive only to the word of God (Matthew 18; 1 Cor. 5). Accordingly, the congregation votes on its leadership, welcomes and dismisses members, and stands accountable to God for its public teaching and preaching.
...the household of God, which is the church of the living God, a pillar and buttress of truth. 1 Tim 3:15 esv
Trinity uses a leadership structure prescribed by the New Testament. We are a congregational church led by elders. These are qualified men who provide spiritual guidance to the congregation. One of our elders is employed by the church. He is commonly called the pastor, however, all of the elders are pastors of the congregation (1 Peter 5.1-5). The qualifications for this office are laid out in 1 Timothy 3 and Titus 1. The elders are the church's leaders who care for the spiritual needs of the congregation.
Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers,
to care for the church of God, which he obtained with his own blood. Acts 20:28 esv
Trinity's deacons support and minister to the church body. The qualifications for this office (given in 1 Timothy 3) show that Deacons must be godly men with hearts to minister and serve God's people . Deacons minister and serve the congregation in a multitude of ways in order to free up the elders to provide spiritual oversight to the body.
. . . those who serve well as deacons gain a good standing for themselves and also great confidence
in the faith that is in Christ Jesus. 1 Timothy 3.13 esv
