The apostolic foundation of the church refers to the apostles’ unique role in the overall design of the church: to be the immediate messengers of Jesus to carry out his authority and preach the gospel faithfully.
The church is comprised of various parts and components. Scripture states that Jesus is the chief cornerstone (Eph. 2:20; 1Pet. 2:4, 6-7), which means that the very existence and the purpose of the church depend on and flow out of the person and the work of Jesus Christ. Scripture also states that the apostles are the foundation of the church (Eph. 2:20). The task at hand seeks to understand the nature and the depth of what this statement truly means. Who are the apostles? What is it about them that uniquely positions them to be the foundation of the church? What does this foundation mean for us today? In this assessment of the nature and the implications of the apostolic foundation of the church, what we observe is that Jesus and his message of the gospel sit at the very heart of the identity and the call of the apostles, thereby the foundation of the church.
No architect would claim that a foundation of a building is unimportant or insignificant. In fact, one can easily argue that it is the most fundamental and crucial part of any building. In Ephesians 2:20, Paul uses this building analogy to emphasize the power of unity available for the church in having Jesus as the chief cornerstone and apostles and prophets[i] as the foundation. What did Paul mean by this statement? In particular, who are the apostles and what makes them important enough to be considered the foundation of the church? What are the relevant applications for the church today? The goal of this essay is to accurately assess the nature and the implications of the apostolic office.
The term apostle connotes an ambassador. In the New Testament this term refers primarily to those men who were commissioned by Jesus to represent him to the world and to be his spokesmen. Thus, close proximity to Jesus in his earthly ministry and being an eye-witness of his resurrection was a requirement for the office (Acts 1:21-22). Their total number, for symbolic reasons, was twelve – against the background of Old Testament Israel this served to signify a new beginning for the people of God (cf. Matt. 19:28; Luke 22:29-30). Thus, Matthias was needed to replace Judas (Acts 1:23-26). Paul is an exceptional case, receiving his apostleship by a slightly different means (1Cor. 9:1; Gal.1:1, 11-12).
The term “apostle” can be used in a looser sense in reference to “church messengers” (2Cor. 8:23; Phil. 2:25), but these references do not refer to the apostolic office as such and will not occupy our attention here.
Jesus affirms the foundational role of the apostles in Matthew 16:18, where he says to Peter, “You are Peter, and on this rock I will build my church.” The imagery is plain: Christ, the builder of the church, founds his church on the apostles. This is precisely what Paul affirms in Ephesians 2:20 where he says that the church is “built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone” (cf. Rev. 21:14; also 1Cor. 3:10-11 in context).
In John 13-17 Jesus clarifies the nature of the apostles’ “foundational” role. These men are to be his designated spokesmen. These who have heard him teach will receive his further teaching via the Spirit, and they will, in turn, give the word of Christ to the world (cf. John 14:24-26; 16:12-15; 17:8, 18, 20). That is to say, the apostles in a very real sense give us Christ. Indeed, when they speak they speak for him and with his delegated authority (e.g., 2Thes.3:6; 1Cor.14:37; etc.). Their teaching is the teaching of Christ, the fulness of the revelation come by him, and this apostolic teaching was, in turn, entrusted or “deposited” to the church “once for all” (1Tim.6:20; Jude 3, etc.). All this informs our understanding of their “foundational” role (Eph.2:20; cf. Matt.16:18, also Rev.21:14; also 1Cor.3:10-11 [in context]).
This same thinking is reflected in 1 John 1:1-3.
“That which was from the beginning, which we have heard, which we have seen with our eyes, which we looked upon and have touched with our hands, concerning the word of life – the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us – that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ.
Here the apostle John affirms that the apostles received their teaching and authority from the Lord Jesus himself and that they (the apostles) mediate the Christ-revelation to us. Simply put, the apostolic witness is the only way to Christ.
This understanding the nature of the apostolic foundation of the church has the following implications:
The church today has the great privilege to stand firmly on the unshakeable foundation of the church and pass the truth of the gospel to others as it has been passed down to us. This ought to give us boldness in proclaiming the gospel even in today’s world. The task is not easy. We can always feel like we are fighting uphill battles. What we can hold onto is that the advancement of the kingdom of God through the gospel ultimately stands on the very heart of the apostolic foundation: the person and the work of Jesus Christ. This has already been established. There is no need to further establish this once-and-for-all foundation. It is because of the strength of this final and authoritative revelation that the church today can be encouraged and motivated to further extend the work of gospel proclamation. As D.A. Carson once said, “The best way to preserve the gospel is by giving it away.”[iv] We must engage in the ministry of the Word with hunger and expectancy as we seek to share the gospel with anyone who comes in contact with us. We can do this with courage and resilience because of our great privilege to be an apostolic church that stands on Jesus, our chief cornerstone. Through it all, in this God-honoring work of sharing and spreading the apostolic Gospel, Jesus guarantees his presence to the end of the age (Matt. 28:19-20).
1 Ephesians 2:20 groups apostles and prophets together when describing the foundational role of the church. Who are these “prophets”? Paul is likely referring to the New Testament prophets who also received divine inspiration at the time of the apostles to work alongside and/or assist the work of the apostles.
