Romans chapter 9 is one of the most challenging passages in all of Scripture—and it’s entirely straightforward. Romans 9 has been the battleground of tense theological debate for centuries, specifically surrounding the concept of God’s sovereignty in election, predestination, and “Calvinistic soteriology.” However, the passage is not nearly as hard to interpret as some have made it out to be… the only question is, can we receive it for what it is?

Sola Scriptura is the fundamental Protestant doctrine, but how should it be practiced? Here’s how Martin Luther—the man who brought Sola Scriptura into the public mind—thought it should be lived out in the Christian life.

Soli Deo Gloria is more than just a theological principle—it’s the lens through which we ought to see everything. Creation, redemption, even our very lives, these will only be truly understood when we understand them as expressions of the glory of God.

Sola Scriptura was the “formal issue” of the Protestant Reformation and is the chief theological commitment upon which the movement, and faithful Christian practice as a whole, is founded.

Solus Christus is absolutely essential to The Gospel—without it, Jesus Christ is demoted to a mere suggestion.

Sola Fide was the “material issue” of the Protestant Reformation and is the chief article by which the Reformed case either stands or falls.

Sola Gratia is the heart of The Gospel—it should be no surprise, then, that it is a central doctrine of Reformed Theology.
