Companion: Deep Study
A condensed companion to the full study. For each section of the expanded outline: key insights, applications, and the application questions for discussion.
Section 1 — The Circumcision Controversy (Acts 15:1–5)
Key Insights
- Men from Judea taught, “Unless you are circumcised… you cannot be saved” (Acts 15:1) — an assault on the gospel itself, adding a work of the law to grace.
- Any addition to grace is a subtraction from Christ; “grace plus” is really “grace minus” (Galatians 2:21).
- Paul and Barnabas contended with “no small dissension and debate,” refusing to let soul-destroying error pass.
- The error arose from within the church — believers “of the party of the Pharisees” (Acts 15:5) still clinging to self-righteousness.
- The Antioch church referred the dispute to “the apostles and the elders” (Acts 15:2) — the seed of conciliar (Presbyterian) government.
Applications
- Rest your standing with God on Christ alone, adding no conditions of pedigree, performance, or ritual.
- Take serious doctrinal error seriously, contending faithfully yet through the ordered fellowship of the church.
- Distinguish disputes that touch the gospel itself from secondary differences.
Application Questions
- Have I added anything to the finished work of Christ as the ground of my acceptance before God?
- How do I respond when serious doctrinal error arises in the church — with apathy, with faction, or with faithful, orderly contention?
Section 2 — Peter’s Testimony: Saved Through Grace (Acts 15:6–11)
Key Insights
- Peter appeals to God’s sovereign initiative in saving the Gentiles (Cornelius, Acts 10), attested by the gift of the Holy Spirit (Acts 15:7–8).
- God “cleansed their hearts by faith” (Acts 15:9) — an inward, faith-received cleansing, not a ceremonial one.
- The law as a way of salvation is an unbearable “yoke” no one has kept (Acts 15:10; Romans 3:20).
- Peter’s climax is pure sola gratia: “we will be saved through the grace of the Lord Jesus, just as they will” (Acts 15:11).
- The striking reversal — Jews are saved as Gentiles are, by grace on identical terms — levels every human distinction at the cross.
Applications
- Lay down the exhausting yoke of performance; labor because you are accepted, not to be accepted (Matthew 11:28–30).
- Let grace kill both pride (we contribute nothing) and despair (grace is fully sufficient).
- Withhold fellowship from no one whom God has cleansed by faith (Romans 15:7).
Application Questions
- Am I trying to bear a yoke of religious performance that God never intended me to carry as the ground of my salvation?
- Do I withhold fellowship or acceptance from fellow believers whom God has plainly received by grace?
Section 3 — James and the Witness of the Prophets (Acts 15:12–21)
Key Insights
- James grounds the ruling not in experience alone but in Scripture: “with this the words of the prophets agree” (Acts 15:15).
- He cites Amos 9:11–12: God rebuilds “the tent of David that has fallen” so that “all the Gentiles” seek the Lord (Acts 15:16–17).
- Gentile inclusion is the fulfillment of the Davidic promise — the reigning Son of David gathering the nations, not a departure from the prophets.
- James’s “judgment” (Acts 15:19): do not trouble the Gentiles with circumcision or the law-yoke.
- The four abstentions (Acts 15:20) are pastoral guidelines to preserve table fellowship and unity, not conditions of salvation.
Applications
- Test every experience and impression of God’s leading against the written Word (Acts 17:11; Isaiah 8:20).
- Be firm on the gospel yet gracious on matters of fellowship, imitating James’s balance.
- Willingly limit personal liberty for a weaker brother’s conscience and the church’s peace (1 Corinthians 8–10).
Application Questions
- Do I test my experiences and impressions of God’s leading against the written Word of God?
- Am I willing to limit my Christian liberty for the sake of a weaker brother’s conscience and the peace of the church?
Section 4 — The Letter to the Gentiles (Acts 15:22–29)
Key Insights
- The decision was corporate and deliberate — “it seemed good… having come to one accord” (Acts 15:22, 25) — reached with “the whole church.”
- The letter disowns the troublemakers, who acted with no authorization from Jerusalem (Acts 15:24).
- It honors Paul and Barnabas as “beloved” who “risked their lives for the name of our Lord Jesus Christ” (Acts 15:26).
- “It has seemed good to the Holy Spirit and to us” (Acts 15:28) — Spirit-guided discernment under the Word, real yet not infallible authority (WCF 31.4).
- The council lays on the Gentiles “no greater burden,” refusing the law-yoke and closing with pastoral warmth.
Applications
- Receive the lawful, biblical counsel of the church with humility (Hebrews 13:17), testing all by the Word.
- Protect the flock from teaching that troubles and unsettles minds; disown error plainly.
- Esteem faithful servants and value clear, written communication of doctrine.
Application Questions
- Do I receive the lawful, biblical counsel and decisions of my church with humility, or do I resist all authority but my own?
- Do my words settle and encourage the minds of fellow believers, or trouble and unsettle them?
Section 5 — The Letter Delivered and the Rejoicing (Acts 15:30–35)
Key Insights
- When the Antioch church heard the verdict, “they rejoiced because of its encouragement” (Acts 15:31) — gospel liberty produces joy.
- Judas and Silas, themselves prophets, “encouraged and strengthened the brothers” (Acts 15:32) — sound doctrine joined to warm pastoral ministry.
- The delegates were “sent off in peace” (Acts 15:33) — the peace the Judaizers had disturbed was restored.
- Paul and Barnabas returned to the church’s normal, healthy life: “teaching and preaching the word of the Lord” (Acts 15:35).
- The whole aim and effect is that believers rest in the grace of the Lord Jesus and go on heeding His Word.
Applications
- Let the gospel of grace produce genuine joy; joylessness may signal a return to a yoke of law.
- Minister truth so as to encourage and strengthen, not merely to inform.
- Pursue and preserve peace after conflict, and give yourself to the ongoing ministry of the Word.
Application Questions
- Does the gospel of grace produce genuine joy in my life, or has my faith become a joyless burden?
- Do I minister truth to others in a way that encourages and strengthens them, and do I pursue peace after conflict?
Section 6 — Paul and Barnabas Divide Over Mark (Acts 15:36–41)
Key Insights
- A pastoral revisit (Acts 15:36) becomes a personnel dispute over John Mark, who had deserted the first journey (Acts 13:13).
- Paul guarded the integrity of the mission; Barnabas, “son of encouragement,” sought the restoration of a fallen brother.
- A “sharp disagreement” (paroxysmos, Acts 15:39) between two godly men — Luke records it honestly, idealizing no one.
- God’s overruling providence: one mission became two, and the gospel advanced on two fronts (Acts 15:39–41).
- The epilogue vindicates grace: Mark, restored, later becomes “very useful” to Paul (2 Timothy 4:11) and writes a Gospel.
Applications
- Extend grace and a second chance to those who have failed, believing grace can make them useful again (Galatians 6:1).
- Trust God’s sovereign providence to bring good even out of conflicts and disappointments (Romans 8:28).
- Hold truth and mercy together; the church needs both standards and restoration, and never writes anyone off.
Application Questions
- Do I extend grace and a second chance to those who have failed, as Barnabas did for Mark?
- Do I trust God’s sovereign providence to bring good even out of my conflicts and disappointments?
Christ, the reigning Son of David, saves Jew and Gentile alike by the grace of the Lord Jesus — cleansing hearts by faith, rebuilding David’s fallen tent by gathering the nations, and ordering His church in truth and peace — so we rest wholly on His finished work and welcome all whom He has welcomed.
