This is where the five solas came from. These were five statements about the content of the Protestant gospel, and by the end of the 1500’s, these were the terms which identified Protestantism. These five phrases are not an extensive statement on theology, but instead served simply as a way to explain what the content of the gospel was to which Protestants held.

The Protestant Reformation threw the Christian world into chaos. At the beginning of the 1400’s the Pope’s authority was absolute and the only means of salvation were the sacraments given under his auspices. There was a secular/sacred distinction that was ironclad, meaning that the priests and laity lived in practically two separate worlds. There was no concept of church membership, corporate worship, preaching, or Bible reading in the churches. And as far as doctrine was concerned, there was no debate—the creeds and declarations from Rome (and soon to be Avignon) were the law.

Things had been this way for six hundred years. In a world where life expectancy was in the 30’s, that is essentially the same as saying that the church had been in the dark forever.

But if you fast-forward to the end of the 1500’s, all of that had been turned on its head. The absolute nature of the Pope’s rule and vanished—in large part owing to the Babylonian Captivity of the church (the 40 year period were two rival popes both ruled, and both excommunicated each other—finally to both be deposed by a church council). Church councils themselves had contradicted themselves so many times that their own authority was openly ridiculed. The Holy Roman Empire was no longer relevant, and the political world had simply passed the Pope by. 

Protestants found themselves in the wake of this upheaval, and there was one major question to be answered: what, exactly, was this new kind of Christian? What did a Protestant believe? The reformation had followed similar and simultaneous tracks in multiple countries, yet at the end of it all the content of Protestantism was pretty much the same. On the essentials, German, English, Swiss, and Dutch Protestants all stood for the same theology. But what was it?

It was easy to understand the beliefs of Catholicism—all one had to do was look at their creeds and the declarations from their councils. But Protestants were so named precisely because they were opposed to all that. So what council would give them their beliefs then?

This is where the five solas came from. These were five statements about the content of the Protestant gospel, and by the end of the 1500’s, these were the terms which identified Protestantism. These five phrases are not an extensive statement on theology, but instead served simply as a way to explain what the content of the gospel was to which Protestants held.

Sola Fide—Faith alone

Solus Christus—Christ alone

Sola Scriptura—Scripture alone

Sola Gratia—Grace alone

Soli Deo Gloria—God’s glory alone

These five solas still live on to this very day. They define what the gospel is for evangelicals worldwide, and also provide a helpful summary—a cheat sheet even—of what marks the true gospel from a religion of works. But historically, these five solas make the most sense when viewed from the perspective of answering the question: what do Protestants believe? In fact, each one of these five is an answer to a particular question:
