Comparing one doctrine?
Begin with a doctrine guide, then read its cornerstone study and focused passage studies.
Every study answers four questions
- What does the passage say in context?
- How do informed Calvinists interpret it?
- What does the text clearly establish?
- What remains inferred or disputed?
One passage, method in view
Worked example
2 Peter 3:9 and the scope of God’s patience
- What both readings affirm
- Christ’s return has not failed. Peter presents the interval before judgment as purposeful divine patience directed toward repentance.
- Representative Reformed reading
- John Gill reads “any” and “all” within the beloved audience and identifies that group with the elect whose effectual calling must be completed before Christ returns.
- The disputed step
- Does Peter’s “toward you” restrict every object of God’s patience to the elect, or is the church receiving an explanation of God’s patience toward a wider world facing judgment?
- Beyond Tulip’s alternative
- The wider chapter moves between the beloved community and the judged world. The article therefore reads the delay as a sincere opportunity for repentance without treating the verse as a complete account of God’s decree.
Check the representative sources: John Gill on 2 Peter 3:9 and John Calvin on 2 Peter 3:9–13. These interpreters do not frame the verse identically.
Why This Debate Matters
These doctrines shape how Christians speak about the character of God, gospel proclamation, assurance, faith, grace, and Scripture’s warnings. Both traditions appeal to Scripture and affirm salvation through Christ alone. That shared ground makes careful comparison more important, not less.
Explore the five points
Total Depravity
Sin reaches the whole person; the dispute is whether grace must regenerate a person before faith.
Unconditional Election
God chooses in grace; the dispute is whether election selects unbelieving individuals or a people in Christ.
Limited Atonement
Christ actually saves; the dispute is whether His atoning provision extends to all or only the elect.
Irresistible Grace
No one comes without grace; the dispute is whether the saving call can finally be resisted.
Perseverance of the Saints
Christ securely keeps His people; the dispute is how that promise relates to warnings and continuing faith.
Featured cornerstone studies
Total Depravity and Total Inability: What Does Scripture Actually Teach?
Christians agree that every person is affected by sin and cannot earn or accomplish salvation. The dispute is whether spiritual death also makes a response to God’s gracious gospel impossible until after regeneration.
Romans 9 and Calvinism: Election, Israel, and God’s Faithfulness
Romans 9 addresses God’s faithfulness amid Israel’s unbelief, Gentile inclusion, mercy, hardening, and faith. This study asks whether that argument proves unconditional individual election to salvation.
Limited Atonement and Universal Provision: For Whom Did Christ Die?
Limited atonement teaches that Christ intended His death to secure salvation effectively for the elect in a way not intended for the non-elect. This study compares that cumulative case with the biblical argument for universal provision and application through faith.
Focused studies
Ephesians 2:1–5: Does “Dead in Sin” Mean Unable to Believe?
The interpretive hinge is whether Paul’s language of spiritual death describes guilt and bondage or also fixes the order of regeneration and faith.
Acts 7:51: What Does It Mean to Resist the Holy Spirit?
The interpretive hinge is whether Acts 7 itself distinguishes the resisted prophetic call from a second inward call that necessarily succeeds.
Hebrews 6:4–6: Were These Genuine Believers?
The interpretive hinge is whether the warning describes regenerate believers or people who shared deeply in covenant blessings without possessing salvation.
