Paul says the church is “built on the foundation of the apostles and the prophets” (Eph. 2:20). I conclude that all we need to know for salvation and sanctification has been given to us through the teaching of the apostles and prophets, and that this teaching is now found in the Scriptures. Now that God has spoken in the last days through His Son (Heb. 1:2), we don’t need further words from Him to explain what Jesus Christ has accomplished in His ministry, death, and resurrection. Instead, we are “to contend for the faith that was delivered to the saints once for all” through the apostles and prophets (Jude 3).
