Discussion Questions

In Jesus’ vine parable (John 15:1–2), David Bercot emphasizes the Father “takes away” fruitless branches and “prunes” fruitful ones—what does that picture suggest about God’s priorities and actions toward people who claim to be “in” Christ, and how does that collide with common assurances offered in modern evangelicalism? JumpstartAnother way to ask: In John 15:1–2, what does it mean that the Father “takes away” branches with no fruit and “prunes” the fruitful ones? How does this challenge common modern evangelical promises about being “in Christ” no matter what?

Bercot argues that both late-medieval Catholicism (pilgrimages, relics, Mass attendance, indulgences) and Luther’s “mental assent” version of faith-alone functioned as “entering heaven without bearing fruit”—what, in the chapter’s terms, actually counts as “kingdom fruit,” and what religious behaviors today might be the modern equivalents of the counterfeit substitutes he lists? JumpstartAnother way to ask: According to the chapter, what counts as real “kingdom fruit”? What church habits today might be like the “fake substitutes” Bercot says people used to rely on?

The chapter claims Luther expected fruit to “automatically follow” Reformation teaching but that the historical result in Germany was “antinomian tendencies” and moral decline (with quotes from Schaff and Luther’s own complaints)—how should Christians weigh “historical fruit” when evaluating a theological system, and what dangers come from refusing to judge a tree by its fruit? JumpstartAnother way to ask: How much should the real-life results of a teaching over time (“historical fruit”) matter when judging a theology? What could go wrong if we refuse to “judge a tree by its fruit”?

Bercot calls Catholic and Lutheran Germany “rotten trees,” connecting them to centuries of wars and even culminating in World War II—what assumptions about God’s rule over nations and the moral trajectory of “Christian societies” are being challenged here, and how does this critique confront typical narratives about “Christianizing culture”? JumpstartAnother way to ask: If “Christian” Germany still produced violence and wars, what does that say about God’s rule over nations and the idea of “Christian society”? How does this push back on the goal of “Christianizing culture”?

The chapter asserts, “The problem is that they never embraced Christ,” even if they embraced Reformation theology; using Bercot’s examples (“Sin boldly,” “no fruit needed”), what does it look like in real life to embrace a theology without embracing Christ, and how can a church tell the difference without turning faith into mere rule-keeping? JumpstartAnother way to ask: What does it look like to agree with Christian ideas but not truly follow Christ in daily life? How can a church tell the difference without turning faith into just checking off rules?

Bercot says a far worse heresy than “thinking you deserve salvation” is “murdering others in the name of Christ,” then lists reformers’ involvement in executions (Zwingli, Calvin, Farel, Melanchthon’s congratulatory letter)—how does this expose what Bercot sees as a catastrophic mismatch between Jesus’ kingdom and coercive power, and how might early Christians have responded to Christians using the sword for doctrinal enforcement? JumpstartAnother way to ask: What is Bercot saying is wrong with using force or execution “in Jesus’ name”? How do you think early Christians would have reacted to Christians using the sword to punish “wrong doctrine”?

In the Servetus account (arrested and burned for an erroneous view of the Trinity), what does the chapter imply about the relationship between “right doctrine” and “Christlike spirit,” and where do you see the temptation today to treat theological precision as weightier than the commands and spirit of Jesus? JumpstartAnother way to ask: In the Servetus story, what does the chapter suggest about having correct doctrine but lacking a Christlike spirit? Where today do Christians treat being theologically exact as more important than obeying Jesus?

Erasmus’ critique of Luther centers on “uproar,” “delight in abuse and sarcasm,” and lack of harmony with “the apostolic spirit,” and Bercot adds Luther’s cursing prayers and tirades—what does this chapter suggest God is like in how He evaluates spiritual leadership, and how should Christians assess teachers whose doctrine seems orthodox but whose speech and posture are contemptuous? JumpstartAnother way to ask: What does this chapter suggest God cares about when He judges spiritual leaders—just correct teaching, or also their tone and character? How should we evaluate a teacher who is “orthodox” but often cruel or mocking in speech?

Bercot recounts Luther urging merciless slaughter of peasants and later boasting, “I…slew all the peasants…All their blood is upon my head, but I cast it on the Lord God”—what does this reveal about the spiritual danger of claiming divine backing for violent or self-serving political actions, and what parallels can you identify in how Christians today justify harshness “for God” or “for truth”? JumpstartAnother way to ask: What danger do you see in claiming God approves your political violence or harsh actions? What are some ways Christians today excuse cruelty by saying it’s “for God” or “for truth”?

The chapter ends with George Sodini’s note (“Soon I will see God and Jesus…Eternal life does not depend on works…how can I…be judged?”) as an “epitome” of easy-believism—what specific beliefs and slogans in contemporary Christianity could produce the same kind of moral immunity Bercot is warning about, and what concrete changes in preaching, discipleship, and personal habits would be necessary to ensure “faith” is inseparable from kingdom fruit? JumpstartAnother way to ask: What beliefs or slogans today could make someone think their actions don’t matter as long as they “believe”? What changes in preaching, discipleship, and personal habits would help make sure faith always produces real kingdom fruit?
