In this episode of our German Reformation series, Dr. James Spencer and Dr. Greg Quiggle pivot to one of the defining features of Protestant tradition: the Reformation Solas—and why they still matter for Christians today.

Rather than beginning with a list of “five solas,” Greg frames the Reformation around three theological questions that generated the solas:

1. What is the Church? (ecclesiology)
2. How am I saved / how do I stand before God? (soteriology)
3. Who or what has ultimate authority to define belief and practice? (authority)

From there, Greg explains the contrast between 16th-century Roman Catholic and 16th-century Protestant answers—especially the difference between church-as-organization (a hierarchical structure) and church-as-organism (the priesthood of all believers). That “priesthood” isn’t only about rights; it also includes responsibility—the idea that ministry is not a spectator sport, and that clergy exist chiefly to equip the saints through the Office of the Word.

The conversation then traces how the solas flow from these questions:

• Sola Scriptura (Scripture alone as final authority)
• Sola Fide (justification by faith alone)
• Solus Christus (Christ alone)
• and how these reshape Protestant ideas of salvation, grace, and the church’s mediating role.

James also presses into a key modern confusion: “Bible alone” does not mean “my interpretation alone.” Both hosts argue that the Reformation assumed a teaching office, catechesis, and doctrinal boundaries—something many modern churches have lost. They connect this to contemporary debates about faith as mere intellectual assent versus faith as a way of lifemarked by trust, repentance, and fidelity.

This episode includes discussion of:

• The three Reformation questions behind the solas
• Church as organism vs. church as organization
• Priesthood of all believers: rights and responsibilities
• The “Office of the Word” and why it still matters
• Catholic sacramental mediation vs. Protestant justification by faith
• Why authority (Sola Scriptura) is the “non-negotiable” dividing line
• Faith as lived trust and repentance—beyond a one-time decision
• Why modern American Protestant individualism isn’t the same as Reformation Protestantism
