Discussion Questions

Dean Taylor warns that “God allows heresies to test the church”; based on the examples of Gnosticism and Marcion, what kinds of “tests” does God seem to be aiming at in His people—intellectual accuracy, loyalty under pressure, humility, love of truth, or something else? JumpstartAnother way to ask: When false teachings show up (like Gnosticism and Marcion), what kinds of things does God seem to be testing in His people—right thinking, staying loyal, humility, love for truth, or something else?

The Gnostics claimed salvation came through secret “gnosis” and that the body/material world was evil or irrelevant; where do you see modern Christian habits that subtly treat salvation as something that “happened in your mind” rather than a life that takes hold of the whole person? JumpstartAnother way to ask: Where do you see Christians today acting like salvation is mostly a thing in your head, instead of a new life that changes your whole person and how you live?

Marcion rejected the Old Testament God as “evil,” denied Jesus’ birth from Mary, and leaned toward universal salvation; what does this controversy reveal about God’s consistency across Old and New Testaments, and why would the early church see a “New Testament-only” God as spiritually dangerous? JumpstartAnother way to ask: What does the Marcion debate teach about God being the same God in both the Old and New Testaments, and why did the early church think a “New Testament-only” God was dangerous?

Dean argues the “center has to be Jesus and the real Jesus,” not a “heresy Jesus,” yet also warns that correcting heresy can become a new “target”; how can a church correct false views of Christ without shifting Christianity into being primarily about winning arguments and policing words? JumpstartAnother way to ask: How can a church correct wrong ideas about Jesus without turning Christianity into mostly arguing and word-policing instead of following Jesus?

Irenaeus compares the Gnostics to taking jewels from a king’s portrait and rearranging them into a fox or dog; what are concrete ways Christians today can “rearrange” Scripture so the outcome still sounds spiritual but no longer matches the plain meaning and moral weight of Jesus’ teaching? JumpstartAnother way to ask: What are some real ways people today can use Bible verses in a rearranged way that still sounds spiritual but doesn’t match what Jesus clearly taught?

Dean connects Gnostic tendencies to evangelical slogans like “Christianity isn’t a religion, it’s a relationship,” “salvation means going to heaven when you die,” and “organized religion is bad”; which of these comparisons feels unfair to you, and which one feels uncomfortably accurate when you examine real church life? JumpstartAnother way to ask: Which comparison to Gnosticism feels unfair—“not a religion, a relationship,” “going to heaven when you die,” or “organized religion is bad”? Which one feels uncomfortably true in real church life?

Using John Wesley’s phrase “demonic faith” (mere mental assent) alongside Dean’s claim that true faith “incorporates every bit of you,” how would you describe the kind of faith that James and Paul both assume—especially in how it shows up in obedience, suffering, money, sexuality, enemies, and daily habits? JumpstartAnother way to ask: What kind of faith do James and Paul expect—one that shows up in obedience and real life choices like money, sex, suffering, forgiving enemies, and daily habits?

In 1 John 4:1–3, John gives a clear test about confessing “Jesus Christ is come in the flesh,” and Dean shows how that can be turned into a quick “repeat after me” salvation formula; what modern “frames” or proof-texts have you seen replace the total call of Christ with a minimal verbal checkpoint? JumpstartAnother way to ask: What are some modern slogans or “proof verses” you’ve seen that reduce following Jesus to saying the right words, instead of living under His full call?

The Donatist crisis grew from bishops handing over Scriptures and offering incense to avoid torture, and then the question of whether their baptisms/ordinations were “valid”; what does this debate expose about God’s view of holiness, repentance, and spiritual authority—and what would you do today if a leader publicly betrayed Christ and later asked to return? JumpstartAnother way to ask: What does the Donatist debate show about holiness, repentance, and spiritual leadership, and what should a church do if a leader publicly betrays Christ and later wants to come back?

Dean describes the Trinity controversy escalating through “amateur theologians,” Arius vs. Alexander, and Constantine’s advisor Hosius urging both sides to “drop it” because the questions weren’t required by Scripture; how do you discern when theological precision is necessary versus when the “contentious spirit fostered by misused free time” is steering the church away from Jesus’ actual commands? JumpstartAnother way to ask: How do you tell when a doctrine debate really needs careful wording, and when it’s just people arguing so much that it distracts the church from obeying Jesus?
