As discussed earlier, Jesus Christ is the first apostle, the ultimate apostle, and source of all apostleship (Heb. 3:1). The twelve apostles were foundational to the church, unique in their office, and represented the new covenant of Jesus Christ to the world. Paul, Barnabas, James, Apollos, and others beyond the original twelve were apostles as well, demonstrated not only by their apostolic teaching but by their apostolic witness “in Jerusalem, and in all Judea and Samaria, and to the ends of the earth” (Acts 1:8).
Paul’s words to Timothy communicated the pattern of continuity and connection with the apostles to future generations when he said: “And the things you have heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others.” (2 Tim. 2:2) These words were put into practice in the first centuries as seen in Tertullian’s description in De Praescriptione Haereticorum when he offers examples of church fathers that stood in historic connection and doctrinal continuity with the original twelve apostles. Interestingly, Tertullian not only mentioned the first-century apostles, but spoke in addition of “apostolic men” (apostolicis uiris), namely, those “who continued steadfast with the apostles.”
While the church or household of God is “built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone” (Eph. 2:20), the apostolic nature and mission of the church continued throughout history. As the Nicene Creed states, we believe in the “one, holy, catholic and apostolic church.” This confession applied to the fourth century church as well as the first. To borrow Tertullian’s phrase, there have been “apostolic men” (apostolicis uiris) who have “continued steadfast with the apostles.” As stated earlier, this is not merely in origin and doctrine, but in mission, character, and life in the Spirit. Such “apostolic men” functioned on the order of the twelve apostles of Jesus, even though they did not necessarily fill an office unique to or like that of the original twelve.
Such apostles or apostolic men, gifted by God, were often sent or commissioned with authority to extend the church to some region or segment of society which previously was without a viable witness to the gospel. They were described as apostles because of their pioneering and ground-breaking work to establish churches where no or few Christian communities existed.
While the list of the “Apostles of the Seventy” is rooted in church tradition, it illustrates the idea that there were apostles beyond the original twelve. For example, Hippolytus of Rome (170-236), a disciple of Irenaeus who was a disciple of Polycarp who was a disciple of the Evangelist and Apostle John, produced an early list of seventy apostles. In The Ochtoechos, John of Damascus confirmed that there were “seventy-two lesser apostles.” Such lists were based on the fact that Jesus “appointed and sent seventy disciples ahead of him,” as described in Luke 10:1. Many, if not most of them would have been among the “five hundred brothers” to whom Jesus appeared following his resurrection from the dead (1 Cor. 15:6). Based on such texts and various traditions of church fathers, the Eastern Church names the “Apostles of the Seventy” as:
James the Brother of the Lord, Mark and Luke the Evangelists, Cleopas, Symeon, Barnabas, Justus, Thaddeus, Ananias, Stephen the Protomartyr and Archdeacon, Philip, Prochorus, Nicanor, Timon, Parmenas, Timothy, Titus, Philemon, Onesimus, Epaphras, Archippus, Silas, Silvanus, Crescens, Crispus, Epenetus, Andronicus, Stachys, Amplias, Urban, Narcissus, Apelles, Aristobulus, Herodion, Agabus, Rufus, Asyncritus, Phlegon, Hermes, Patrobus, Hermas, Linus, Gaius, Philologus, Lucius, Jason, Sosipater, Olympas, Tertius, Erastus, Quartus, Euodias, Onesiphorus, Clement, Sosthenes, Apollos, Tychicus, Epaphroditus, Carpus, Quadratus, Mark called John, Zenas, Aristarchus, Pudens, Trophimus, Mark nephew of Barnabas, Artemas, Aquila, Fortunatus, and Achaicus.
The point of this list here is not to say that these were the seventy disciples that Jesus sent (ἀπέστειλεν, aposteilen) ahead of him (Luke 10:1) but that church fathers have described other apostles beyond the original twelve. Such lists were based on the NT, traditions passed down from church fathers, and accounts of early historians. The fact that such lists include two of the Evangelists—Mark, the companion of Peter, and Luke, the companion of Paul—makes it, at least in principle, difficult to refute. They were authors of canonical scriptures, the written form of the apostles’ teaching.
Beyond the seventy, the Eastern, Roman, and Protestant branches of the church have identified historically additional missionaries as apostles, giving further evidence of the church’s apostolic nature. Many of these apostles are:

•Hudson Taylor, Apostle to China, 1832-1905
•Nicholas Kasatkin, Apostle to Japan (1836 – 1912)
The title of apostle given to these pioneering leaders through the church’s history describes them as gifted by God, sent or commissioned with authority to extend the church to an area without a viable witness to the gospel. This list is not to establish that they were necessarily all apostles but that the church historically has identified certain people as such. It can be argued that while their work was built on the foundation of Jesus and the original twelve apostles, many had ministries that were at least equal to if not greater in scope or influence for the gospel than the original twelve apostles of Jesus.
Is the “apostolic church” missional? The traditions of the Eastern, Roman, and Protestant churches argue that it is. Continued.
 Tertullian, De Praescriptione Haereticorum: XXXII, “ex apostolis uel apostolicis uiris, qui tamen cum apostolis perseuerauerit”; “of the apostles or of apostolic men,—a man, moreover, who continued steadfast with the apostles.”
 Hippolytus’s list of the Seventy Apostles was regarded dubious, and thus put in the Appendix of his works in the collection of Early Church Fathers.
 He changed: “The all-praised ten and twain, leading the seventy-two, their rivals in zeal, were manifested as perfect.”
 Some manuscripts say seventy-two.
