Cornerstone Church is an elder-led congregational church. That is, we have a church led by men who submit to the body of Christ (Ephesians 5:21; 1 Timothy 5:17-20), and we have a church body that submits to its appointed leaders (Hebrews 13:7, 17).  The biblical term “elder” is used interchangeably with other words like pastor, overseer, and shepherd throughout Scripture. Though we call our vocational elders “pastors” because they are supported financially to fulfill the role of elder, ultimately all elders are pastors and all pastors are elders (Acts 20:13-37; 1 Timothy 3:1-7; Titus 1:5-9; 1 Peter 5:1-4).

Matt Proctor serves as our teaching pastor. He met his wife Carrie at Iowa State University. They have 3 boys and a girl. Matt is a native Iowan who loves people, sports, and books (see his recommended reading list here). Matt serves as a volunteer chaplain for the Marion Police Department, board member for Serve the City, and as a steering team member for the The Gospel Coalition Iowa.
