What is apostolic succession?
Question 09018
The doctrine of apostolic succession is one of the foundational claims of Roman Catholic, Eastern Orthodox, and some Anglican ecclesiology. It asserts that the authority of the original apostles has been transmitted in an unbroken chain through the laying on of hands from bishop to bishop, from the first century to the present day. The claim carries enormous practical consequences: if valid, it means that churches outside this chain lack legitimate ministry, valid sacraments, and full participation in the Church Christ founded. If invalid, it means that a vast institutional structure rests on a foundation the New Testament does not supply.
What the Claim Involves
Apostolic succession, as understood by Rome and the Orthodox churches, holds that Christ gave authority to the apostles, the apostles passed that authority to bishops through ordination, and those bishops have in turn passed it down through an unbroken line to the present day. This chain of succession is held to guarantee both the validity of the sacraments administered by those bishops and the doctrinal fidelity of the churches they govern. The Pope, as the claimed successor of Peter, stands at the apex of this structure in Catholic theology, with the promise of Matthew 16:18 (“on this rock I will build my church”) interpreted as establishing Peter as the first Bishop of Rome and the foundation of an enduring papal office.
The practical implication is stark. If apostolic succession is necessary for valid ministry, then Protestant churches, which broke from this chain at the Reformation, do not have valid ordinations, valid Eucharists, or, in the fullest sense, valid churches. This is not a theoretical point; it is the official position of Rome. The Second Vatican Council’s Unitatis Redintegratio (1964) acknowledged Protestant communities as “ecclesial communities” but withheld the designation “church” in the full theological sense precisely because they lack apostolic succession.
What the New Testament Actually Shows
The apostles held a unique, unrepeatable office. They were eyewitnesses of the risen Christ (Acts 1:21-22; 1 Corinthians 9:1), personally commissioned by Him, and endowed with authority to lay the foundation of the Church (Ephesians 2:20). Paul’s apostleship, though it came later, met the same criteria: he had seen the risen Lord (1 Corinthians 15:8) and was directly called by Him (Galatians 1:1). The foundation-laying function of the apostles is, by definition, unrepeatable. A foundation is laid once; it is not re-laid in every generation.
The New Testament shows the apostles appointing elders and overseers in the churches they planted (Acts 14:23; Titus 1:5), and it prescribes qualifications for those offices (1 Timothy 3:1-7; Titus 1:5-9). What it does not show is a formal ceremony of apostolic succession in which the unique authority of the apostles was transferred to their successors. Timothy and Titus received authority from Paul, but neither is called an apostle, and the authority they exercised was derived from Paul’s apostolic instruction, not from an office equal to Paul’s that they would then transmit to others. The Pastoral Epistles instruct Timothy and Titus to appoint qualified leaders, not to pass on apostolic authority in a chain.
The claim that Peter was the first Bishop of Rome, and that the papal office is the continuation of his apostolic authority, faces significant historical difficulties. Peter was undoubtedly a prominent figure in the early church and was present in Rome at some point during his ministry. The claim that he served as “bishop” of Rome in the later institutional sense, however, imports a later ecclesiastical structure back into the first century. The letter Paul wrote to the Romans makes no mention of Peter’s presence or authority there. The earliest Roman church leadership appears to have been a plurality of elders, consistent with the pattern visible throughout the New Testament, rather than a single monarchical bishop. The monarchical episcopate developed gradually during the second century, and it is this later development that the doctrine of apostolic succession reads back into the apostolic period.
Where the Real Succession Lies
The New Testament is emphatic about what must be preserved and transmitted across generations, and it is not an institutional chain of ordination. It is the apostolic teaching. Paul’s charge to Timothy is, “What you have heard from me in the presence of many witnesses entrust to faithful men, who will be able to teach others also” (2 Timothy 2:2). The four-generation chain Paul describes (Paul to Timothy to faithful men to others) is a chain of doctrine, not of office. The test of a church’s legitimacy is whether it holds and teaches the apostolic gospel, not whether its ministers can trace an unbroken line of ordination back to the first century.
This is precisely where the Reformation’s insistence on sola Scriptura becomes decisive. If the apostolic teaching is preserved in the New Testament, then fidelity to Scripture is the true mark of apostolic succession. A church that teaches the gospel faithfully stands in genuine continuity with the apostles, regardless of its organisational lineage. A church that has an unbroken institutional chain but teaches doctrines the apostles never taught, doctrines like purgatory, the treasury of merit, the Immaculate Conception, and papal infallibility, has the form of succession without its substance.
So, now what?
The doctrine of apostolic succession invests enormous authority in an institutional structure that the New Testament does not establish. What the apostles left behind was not an office to be inherited but a deposit of truth to be guarded and proclaimed. The believer’s confidence rests not in the unbroken chain of bishops but in the unbroken Word of God, which has been “once for all delivered to the saints” (Jude 3) and needs no institutional supplement to retain its authority. The church that holds fast to the apostolic gospel, teaches the Scriptures faithfully, and worships Christ alone is the church that genuinely continues what the apostles began.
“So then, brothers, stand firm and hold to the traditions that you were taught by us, either by our spoken word or by our letter.” 2 Thessalonians 2:15 (ESV)
