Acts 15 and the Council of Florence: What It Settled
Short answer: The Council of Florence was a fifteenth-century assembly held mainly at Ferrara and then Florence, beginning in 1438, aimed at reuniting the Eastern Orthodox and Western Catholic churches. It reached reunion decrees that were soon rejected by most of the Orthodox world. The New Testament parallel is the Jerusalem council of Acts 15, where the apostles settled whether Gentile believers must be circumcised to be saved. Acts 15:1 records the dispute plainly: some men taught, unless you are circumcised after the custom of Moses, you can not be saved. The apostolic answer was that salvation is by grace through faith, not by submitting to the law. Florence is not that council, but the two raise related questions about authority, tradition, and how the church decides contested matters. Christians still weigh those questions differently today.
What the Council of Florence actually was
The Council of Florence is the name usually given to a council that opened at Ferrara in 1438 and moved to Florence in 1439, then continued at Rome. Its purpose was to heal the long rift between the Greek East and the Latin West, a division that had hardened since 1054. Emperor John VIII and a delegation including the patriarch Joseph II traveled west, largely hoping for military help against the Ottoman threat.
Delegates debated purgatory, the procession of the Holy Spirit, the use of leavened or unleavened bread, and above all the authority of the bishop of Rome. Several reunion documents were signed, and the decree Laetentur Caeli in 1439 announced union. But when the Greek delegates returned home, their agreement was widely repudiated. Mark of Ephesus refused to sign, and the fall of Constantinople in 1453 ended any practical hope of union.
So Florence is best described as a real council with real decrees that failed to achieve lasting reunion. Historians debate how much genuine agreement existed and how much was pressed by political desperation. Either way, Florence shows how hard it is for divided churches to settle questions of doctrine and authority, and it invites comparison with the far more decisive council recorded in Acts 15.
Acts 15: the apostolic council and its question
Acts 15 opens with a sharp conflict. Acts 15:1 states, Unless you are circumcised after the custom of Moses, you can not be saved. Paul and Barnabas disputed with these teachers, and the church sent them to Jerusalem to consult the apostles and elders. This was not a minor administrative matter; it touched the very terms of salvation.
The debate in Jerusalem was direct. Some believers from the Pharisees insisted that Gentiles must be circumcised and keep the law of Moses. Peter answered by recalling how God had given the Spirit to Gentiles, and James concluded that God had visited the nations to take from them a people for his name. The council then sent a letter to the Gentile churches.
That letter distinguishes sharply between what is required for salvation and what is asked for the sake of fellowship. The decree did not impose circumcision. It asked Gentile believers to abstain from things polluted by idols, from sexual immorality, from what is strangled, and from blood. The verdict was that the law was not the door into the church; grace was.
Why the Jerusalem council settled salvation by grace
The apostolic reasoning rested on what God had already done. Peter argued that God, who knows the heart, bore witness by giving the Holy Spirit to the Gentiles, making no distinction between Jew and Gentile, cleansing their hearts by faith. If God had already accepted them, requiring circumcision would be testing God and putting a yoke on disciples that neither the fathers nor the apostles could bear.
The conclusion drawn in Acts 15:11 is that we are saved through the grace of the Lord Jesus, just as the Gentiles also are. That sentence is the theological heart of the chapter. It does not merely lower a requirement; it names the only ground of salvation. Grace is not a supplement to law-keeping, and circumcision is not a second step after faith.
James then supported the decision from Scripture, citing the prophets. The council did not invent a new gospel; it recognized what God was doing and read the Scriptures accordingly. The result was a settled answer for the churches, delivered by chosen men and received with joy. The question of how a sinner is accepted before God had a clear apostolic answer.
Florence and Jerusalem: overlap and difference
It is easy to overdraw the comparison. Florence debated the procession of the Spirit, purgatory, and papal authority; Jerusalem debated circumcision and the law. The specific questions are not the same. Still, both councils raise the deeper issue of how the church authoritatively decides contested doctrine, and what weight tradition carries alongside Scripture.
At Jerusalem, the apostles and elders could say that the Holy Spirit guided their judgment, and their letter carried the authority of those who had walked with Jesus. Florence could claim continuity with that council, but its decrees did not command the same reception. Most of the Orthodox churches rejected its union. That difference does not prove Florence was wrong on every point, but it warns against assuming that any later assembly speaks with apostolic finality.
Where faithful Christians differ, honesty requires saying so. Catholics, Orthodox, and Protestants read the relationship between Scripture, councils, and tradition in genuinely different ways. Acts 15 gives all of them the same standard: the gospel of grace must not be compromised, and church decisions are to be tested by the word of God.
What the letter to the Gentiles did and did not require
The council's letter is often misread. It did not create a new set of laws for Gentiles to obey in order to be saved. The opening words explain the motive: it seemed good to the Holy Spirit and to us to lay no greater burden than these necessary things. The four items listed concerned table fellowship and public witness in a context where idolatry was pervasive.
Abstaining from blood and strangled meat reflected sensitivities rooted in the Old Testament and still alive among Jewish believers. Avoiding things polluted by idols and sexual immorality guarded Gentile converts from the very sins that surrounded them in pagan cities. These were not terms of salvation; they were terms of peaceful coexistence in one body.
Paul's later writing confirms this reading. In 1 Corinthians 8 and 10 he treats food offered to idols with considerable freedom, while warning against causing a brother to stumble. The Jerusalem decree, rightly understood, protects unity and holiness without reintroducing law as the basis of acceptance. That distinction matters whenever churches today multiply requirements that Scripture does not impose.
How the gospel was argued, not merely asserted
Acts 15 is striking for its method. The council did not simply vote. There was much discussion, then testimony about what God had done among the Gentiles, then appeal to Scripture. Peter recounted experience, Paul and Barnabas reported signs and wonders, and James cited the prophets. The decision emerged from weighing evidence and Scripture together.
That pattern is instructive. The apostolic church reasoned in public, allowed debate, and welcomed testimony about God's work. They did not treat disagreement as automatically sinful. Yet they did reach a definite conclusion and send it to the churches, expecting them to follow it. Unity and clarity were both valued, and neither was sacrificed for the other.
Contrast this with councils that end in ambiguous formulas or political compromises nobody receives. Method matters. A council that silences dissent, or that reaches a conclusion unsupported by Scripture, has not followed the pattern of Acts 15. The Jerusalem council is a model of resolving conflict by attending to God's word and God's work, then acting with humility and courage.
What Acts 15 means for Christians today
The abiding lesson is that salvation is by grace, received through faith, apart from works of the law. Whenever a church adds a requirement to the gospel, whether circumcision, a particular ritual, or any human tradition treated as necessary for acceptance, it repeats the error of the teachers at Antioch. Acts 15:11 keeps the focus where it belongs: we are saved through the grace of the Lord Jesus.
A second lesson concerns unity. The council sought a solution that welcomed Gentiles fully while preserving fellowship with Jewish believers. Ephesians 4 urges believers to keep the unity of the Spirit in the bond of peace, and the Jerusalem letter pursued exactly that. Doctrinal clarity and practical charity are not enemies; the apostolic church practiced both.
A third lesson concerns authority. The council's decision carried weight because it was apostolic and scriptural. Later councils may be useful, and Florence was a serious attempt at reconciliation, but no later assembly can overturn the gospel the apostles once delivered. Believers today do well to test every council, ancient or modern, by the same standard.
Biblical fidelity check
Acts 15 establishes certain things clearly. It establishes that circumcision and law-keeping are not required for Gentile salvation, that God justifies by faith, and that the apostolic church could settle a doctrinal dispute and deliver a binding decision to the churches. It also records the specific requests made of Gentile believers for the sake of fellowship.
Acts 15 does not establish that every later church council carries the same authority as the apostles, nor does it guarantee that whatever a council decrees is correct. It does not describe Florence, which occurred nearly fourteen centuries afterward, and it should not be used as proof text for either side in later Catholic-Orthodox disputes. Nor does the chapter abolish all Christian moral teaching; it rejects law as the ground of justification, not holiness as a way of life.
A common misreading treats the four prohibitions as the church's new law for salvation. That contradicts the plain sense of the letter, which says these were necessary things for fellowship, not conditions of acceptance, and it contradicts Acts 15:11, where salvation is attributed to grace. Another misreading treats the council as a precedent for any majority vote settling doctrine, regardless of Scripture. The council argued from God's work and the prophets, not from numbers alone.
Other passages that speak to Acts 15
Several passages illuminate the issues raised at Jerusalem and, by extension, at later councils. Galatians 2:1-10 records Paul's own account of going up to Jerusalem and defending the freedom of the gospel, showing that the question was not settled without conflict. John 17:20-23 records Jesus praying for the unity of those who would believe through the apostles' word, a unity grounded in truth. Ephesians 4:1-6 calls believers to walk worthily of their calling and to keep the unity of the Spirit, naming one Lord, one faith, one baptism. And 2 Timothy 3:16-17 grounds the church's teaching in the God-breathed Scriptures, profitable for teaching, reproof, correction, and instruction in righteousness. Together these passages frame how the church should handle disputes: with Scripture as the standard, the gospel as the treasure, and unity as the goal.

Context, Theology, and Application, 1 Corinthians 1: Called, United, and Boasting in the Lord, and 1 Corinthians 10: Warnings and Freedom.
Frequently asked questions
Was the Council of Florence the same as the Jerusalem council in Acts 15?
No. The Jerusalem council took place around 49 AD and involved the apostles and elders deciding whether Gentiles must be circumcised. The Council of Florence met in 1438 to 1445 and sought to reunite the Eastern Orthodox and Western Catholic churches, debating issues like purgatory, the procession of the Holy Spirit, and papal authority. They are separated by nearly fourteen centuries and address different questions, though both raise the issue of how the church decides contested doctrine.
Did the Council of Florence succeed in reuniting the churches?
It reached reunion decrees, including Laetentur Caeli in 1439, and some eastern delegates signed them. But the agreement was widely rejected when the delegates returned home. Mark of Ephesus refused to sign, and most of the Orthodox world repudiated the union. The fall of Constantinople in 1453 removed any practical hope. So Florence produced real documents but no lasting reunion, and the division between East and West continued.
What does Acts 15 teach about salvation and the law?
Acts 15 teaches that salvation is by grace through faith, not by circumcision or law-keeping. Peter argues that God cleansed Gentile hearts by faith, and Acts 15:11 says we are saved through the grace of the Lord Jesus. The letter to the Gentiles laid no greater burden than a few things needed for fellowship. The chapter does not reject holiness; it rejects law as the ground of acceptance before God.
