Perhaps you’ve heard a pastor or preacher say, “We are saved by grace alone, through faith alone, in Christ alone, as revealed by Scripture alone, to the glory of God alone.” Those are known as the “five solas” (or “solae”) because in Latin they are: Sola gratia, sola fida, solus Christus, sola scriptura, and soli Deo gloria. Although all five were not articulated together until the 20th century, the first two, grace alone and faith alone, were mentioned by some of the 16th-century Protestant Reformers to summarize what they felt was most wrong with Roman Catholicism. It isn’t easy, however, to summarize all that God has revealed about salvation in Scripture with four Latin words. In fact, it is impossible. That is one reason why God gave us an entire Bible, and not just four words.

Anyone who reads the Bible and filters everything he reads through the first two solas is going to be scratching his head. That is always the problem with theological mantras. They are limited by their brevity, and if they’re unduly elevated, they can end up supplanting Scripture. If you find yourself often saying to yourself as you read the Bible, “That can’t mean what it says, because it doesn’t agree with one of the solas,” then you’ve got a problem. You are filtering the Bible through your theology rather than what you should be doing, and that is filtering your theology through the Bible.
But it can get even worse. Not only is Scripture often twisted to fit into theological mantras, but the mantras themselves are often twisted to mean what they did not originally mean. That has certainly happened regarding the first two solas. In the end, both Scripture and mantras are misused. Allow me to explain.
