Since the Council of Constantinople (AD 381), the Christian church has confessed creedally four attributes of the true church, that she is “one, holy, catholic and apostolic.” Ephesians 2:20 teaches the church’s apostolicity, for the church is “built upon the foundation of the apostles and prophets.”
Thus the apostolicity of the church is biblical and creedal, but what does it mean? On the day of Pentecost, the beginning of the New Testament age, the church was gathered through the preaching of the apostles, and the church “continued steadfastly in the apostles’ doctrine” (Acts 2:42). Today, apostolic doctrine is contained in the New Testament which is the completion and fulfilment of the Old Testament. Therefore that church is apostolic which is wholly characterised by the truth taught by the apostles in sacred Scripture, and Christian ministers are successors to the apostles if they preach apostolic doctrine.
Ephesians 2:20 teaches that apostolicity is the foundation of the church, for the church is “built upon the foundation of the apostles and prophets.” The holiness of the church is its beauty (Eph. 5:26-27); not its foundation. The catholicity of the church is its universal extent including all nations, languages, age groups etc. (Rev. 7:9); not its foundation. The unity of the church is its spiritual and numerical oneness; not its foundation. As the “foundation” of the church, apostolicity is the basis for the church’s holiness, catholicity and unity. The true church possesses apostolic holiness, apostolic catholicity and apostolic unity. Thus ecumenical relations between congregations and denominations must begin with doctrinal discussions: Do we agree together on the apostolic faith?
Moreover, there is only one foundation of the church; not two or more. The basis of the church is not apostolicity andunity or holiness or catholicity. Nor is the church based upon apostolicity and man’s free will or modern science or church tradition. The church’s sole foundation is the apostolic truth of the Holy Scriptures that reveal Jesus Christ crucified, risen and reigning, for He personally is the foundation of the church (I Cor. 3:11).
Foundations, of course, are laid once, and the foundation of the church can never be re-laid. The apostolic faith “was once [for all] delivered to the saints” (Jude 3). As a wise builder, God’s foundation is strong enough to support the whole church of all ages. Thus departing from apostolic doctrine—the truth about the Triune God, Scripture, creation, sovereign grace etc.—is tampering with the foundation of the church and results in the fall of a congregation or denomination. People may still attend, but spiritually the congregation is degenerating and on the way to becoming a false church. Churches with apostles and prophets today not only fail to understand the nature of these temporary, extraordinary offices, but they also add to and thereby undermine the foundation of the church: the biblical, New Testament “apostles and prophets” (Eph. 2:20; cf. 3:5). The claim that there are apostles and prophets today necessary involves their receiving direct, verbal revelation from God (other than that in the 66 God-breathed books of Holy Scripture). This denies the all-sufficient Word of God (Ps. 19:7-11; II Tim. 3:16-17) and the all-sufficient foundation of the church (Eph. 2:20).
Foundations also determine the length and breadth, and thus the shape, of a building. False doctrines in a church not only tear up the foundation; they also lay an additional foundation. All that claims to be church but is not built on the apostolic foundation is under the judgment of God.
The best way to demolish a building is not to smash its windows or its chimney or even its walls but to destroy the foundation that supports the whole edifice. Likewise, the most effective way to overthrow a church is to undermine its foundation: apostolic doctrine. Thus, openly or subtly, false teachers attack total depravity, justification by faith alone, unconditional election and reprobation etc.; and undermine the Reformed creeds that summarise apostolic truth.
All this enables us to test instituted churches by the light of God’s Word. The key question is this: Is this congregation or denomination apostolic in all things? Is this or that church wholly characterised by apostolic teaching so that it is a “pillar and ground of the truth” (I Tim. 3:15) holding up the truth of Jesus Christ in a truth-hating world? Are the three marks of the church present: apostolic preaching, apostolic sacraments and apostolic church discipline? Is the congregation apostolic in its worship, prayers, church polity, offices (minister, elder and deacon), instruction of covenant children, evangelism etc.?
Membership in an apostolic church is honouring Jesus Christ who is present where apostolic truth is preached, believed, loved, confessed, defended and suffered for. Such churches are places where its members “grow in grace” through “the knowledge of our Lord and Saviour Jesus Christ” (II Peter 3:18), the one set forth in all His riches in apostolic teaching.
