Lesson Five: The History of Sola Fida

Lesson Seven: History of Sola Gratis

In this episode, Dr. Matt Castro explores the rich historical and theological development of the doctrine of Sola Gratia—Grace Alone. Tracing the theme of grace from Scripture through the early church, Augustine, Aquinas, and into the Reformation, this lesson highlights grace as God's sovereign response to human sin. From Augustine’s Confessions to Luther’s rediscovery of grace in Romans, the episode emphasizes that salvation is not earned but entirely a gift from God. Listeners will come away with a deeper understanding of why grace is foundational to Christian identity, assurance, and transformation.

Lesson Six: The Theology of Sola Fida

In this session of the Wednesday Summer Equip Class on the Five Solas of the Reformation, Dr. Matt Castro explores the doctrine of Sola Fide—justification by faith alone. Building on the previous lesson’s historical background, he explains the theological heart of the Reformation’s teaching that sinners are declared righteous by God’s grace through faith in Christ, apart from works or sacraments. The lesson contrasts medieval Catholic views of cooperation and merit with the Protestant insistence on faith as the sole instrument of justification. Through Scripture and Reformation history, listeners are invited to see how this doctrine preserves the sufficiency of Christ’s atoning work and the believer’s assurance of salvatio

Citizens of Heaven with Michael Ebbs

In this episode of the Partners in Citizens podcast, host Matt Castro is joined by friend and political enthusiast Michael Ebbs for a thoughtful conversation about tariffs, trade policy under President Trump, and broader questions about globalism. They discuss the economic logic behind tariffs, their local and international impacts, and the historical failures of protectionist policies like the Smoot-Hawley Tariff Act. Drawing on personal experience in higher education and international student dynamics, Mike shares how immigration and global trade fuel innovation and stability. They also explore the Christian and ethical dimensions of global trade, arguing that open markets can help lift people out of poverty and foster collaboration. The episode closes with reflections on Congress’s role in regulating tariffs and the potential need to rein in executive power over trade policy.

Lesson Five: The History of Sola Fida

In this episode of our Summer Equipped Class on the Five Solas, Pastor Matt Castro explores the historical development of Sola Fide—faith alone. We trace how medieval Catholic theology developed a complex sacramental system that conveyed grace through rituals such as baptism and the Eucharist, requiring human cooperation for salvation. Matt explains how the Reformers rejected this synergy, insisting on justification by faith alone in Christ’s work. This episode sets the stage for understanding the core theological conflict of the Reformation and prepares listeners for a deeper biblical discussion in the next session.

Lesson Four: The Theology of Solus Christus

In this episode of our Summer Wednesday Night series on the Five Solas, Pastor Greg Sukert teaches on Solus Christus—Christ Alone. He explores why the Reformation insisted that salvation is found in Christ alone, without religious “add-ons,” and how this truth counters both historical and modern distortions of the gospel. Using Galatians 3 and the teachings of Peter and Paul, this lesson calls us to reject performance-based faith and rest fully in Christ’s finished work. Join us as we rediscover the simple, life-giving message at the heart of the Reformation: grace alone, faith alone, in Christ alone, according to Scripture alone, for God’s glory alone.
