Evan Gaertner and Mike Yagley discuss how our identity is found in our relationship with God instead of our works. When our relationship is secured in the righteousness of Christ, then our will is free to share life with God and with other people. Without Christ, our lives are lived in bondage to our transactions.

This episode features a beer from a Wisconsin brewery, Stubborn Brothers Brewery. Mike and his wife went for a ride in their camper around Lake Michigan. He had a great Reuben there and enjoyed the beer. American Wheat. Shawano has to be a great city because this is where this beer is from, but also because this is where Evan was born.

Evan Gaertner and Mike Yagley continue their conversation about Martin Luther’s response to Erasmus about the condition of the human will. This episode focuses on why Martin Luther thinks this conversation is important. Righteousness according to moral efforts will always fall short, and God desires that we find our righteousness by having faith in Him. This sort of righteousness must be revealed by God Himself and is not found by our own vain quests for holiness.

Mike Yagley and Evan Gaertner review De Servo Arbitrio, which means Bondage of the Will, by Martin Luther. It was published in 1525 in response to Erasmus’ work from 1524 on humanity in De libero arbitrio diatribe sive collatio or On Free Will. The first part of this book by Luther is a recounting of the arguments made by Erasmus. This podcast picks up with Luther’s position. Luther walks through key passages of Scripture to show that the work of God is necessary for salvation.

This episode is the beginning of a multi-part examination of this fundamental work by Martin Luther.

In Episode 91 of Grace on Tap, Evan Gaertner and Mike Yagley dive into the turbulent years following Luther’s stay at the Wartburg Castle—when the Reformation teetered on the edge of chaos. While Luther hid under Frederick’s protection, self-proclaimed prophets like Nikolaus Storch and Thomas Müntzer began to claim direct revelations from God, turning reform into fanaticism. Müntzer’s dark preaching of divine revolution and peasant uprising sent shockwaves through Germany, forcing Luther to return to Wittenberg and deliver his famous Invocavit Sermons to restore order and direction. But even as Luther reestablished calm, the emperor, the pope, and Frederick’s own relatives pressed hard for him to hand over the troublesome reformer.

This episode traces how Frederick the Wise navigated the storm with remarkable restraint and political cunning. Through papal pressure, imperial mandates, and internal dissent, Frederick maintained a careful appearance of neutrality while quietly protecting Luther’s cause. His steady leadership, even amid the radicalism of Müntzer and the violence of the Peasants’ War, preserved the fragile early Reformation. Join us as we explore how God worked through Frederick’s wisdom, patience, and faith during one of the most volatile chapters of church history—and how his legacy continues to shape our understanding of godly leadership today.

We utilized throughout this eight-part series the book, Frederick the Wise: Seena nd Unseen Lives of Martin Luther’s Protector. This book is a biography written by Sam Wellman and published by CPH.

The 90th episode of Grace on Tap traces Frederick’s efforts to secure a fair hearing for Luther in the face of papal pressure, culminating in the dramatic events at Worms. Listeners for how Frederick’s chancellor, Bruck, tirelessly negotiated with imperial and papal representatives, how Glampion tried to limit Luther’s protection, and how Frederick worked behind the scenes to keep Luther on the agenda when others sought to silence him. His ability to balance loyalty to the empire with his growing support for reform made him one of the most pivotal figures of the early Reformation.

Finally, Mike and Evan follow the story beyond Worms, as Frederick arranged Luther’s “kidnapping” to Wartburg Castle, navigated disagreements with Luther over publications, and quietly began dismantling his relic business in response to the gospel. It’s a story of faith, strategy, and quiet courage. Don’t miss this deep dive into the life and leadership of Frederick the Wise, a prince whose prudence shaped the course of history.

Frederick the Wise shielded Martin Luther during the earliest and most uncertain years of the Reformation. Far more than a footnote in Luther’s story, Frederick emerges as a skilled statesman navigating the volatile mix of church corruption, shifting feudal structures, and the rising voices of peasants and humanists. This episode explores the events of 1520 to see how Frederick acts as a leader, balancing faith, politics, and survival in a rapidly changing Europe.

Mike Yagley and Evan Gaertner trace how Frederick managed student riots in Wittenberg, negotiated with papal envoys, and framed Luther’s case so it couldn’t be dismissed as mere rebellion. By carefully demanding impartial judges and keeping trials close to German soil, Frederick gave Luther a chance to survive and speak the truth.

1518-1519 was a critical turning point in the politics of the Reformation. Join Mike Yagley and Evan Gaertner as they follow Frederick the Wise as he navigates the turbulent waters between Pope Leo, Emperor Maximilian, and the rising voice of Martin Luther. From the tense Reichstag in Augsburg back-channel negotiations that kept Luther out of Rome, Frederick’s political skill kept the Reformation able to stay focused on the theology of the Reformation.

The sudden death of Emperor Maximilian threw Europe into chaos, forcing the Elector of Saxony to mediate petty feuds, delicate alliances, and steer the direction of the imperial election. At one point, he came within one vote of becoming Emperor.

Frederick found himself under increasing pressure from both Rome and his own allies. Papal authority was being shook by the exposure of the fraudulent origins of the “Donation of Constantine.” This episode is great for those who love conversations about theology, diplomacy, human drama, and Reformation history.

Evan Gaertner and Mike Yagley continue a discussion about Frederick the Wise’s ability to protect Martin Luther from the combined pressure of the pope and the emperor. This episode largely focuses on the events of 1518.

After Luther posted his 95 Theses, the Church wasted no time in seeking to silence him. Pope Leo X demanded that Luther be sent to Rome, where execution likely awaited him. But Frederick saw the danger, not only to Luther, but to the fragile balance of power in the Holy Roman Empire. What followed was a masterclass in political restraint and strategic genius.

We walk through the events of the 1518 Reichstag in Augsburg, where Frederick successfully blocked a sham “crusade” that would have aligned the emperor with the pope. He also managed to preserve his electoral influence by denying Emperor Maximilian’s request to pre-crown his grandson Charles, all while keeping Luther safe at home. You’ll hear how about the interrogation of Luther by Cardinal Cajetan unfolded. We will also discuss how a drunken brag changed the course of diplomacy.
