The Latin word sola means „alone” or „only.”
The Five Solas are five Latin phrases (or slogans) that emerged during the Protestant Reformation and that summarize the Reformers’ basic theological convictions on what they believed to be the essentials of the Christian life and practice.
The Five Solas are:
1. Sola Scriptura (“Scripture alone”): Scripture alone is our highest authority.
2. Sola Fide (“faith alone”): We are saved by grace alone, through faith alone.
3. Sola Gratia (“grace alone”): We are saved by grace alone, through faith alone.
4. Solus Christus (“Christ alone”): Christ alone is our Lord, Savior, and King.
5. Soli Deo Gloria (“glory to God alone”): We live for the glory of God alone.
The following is a brief explanation of each.
