The Five Solas are five Latin phrases (or slogans) that emerged from the Protestant Reformation intended to summarize the Reformers' basic theological principles in contrast to certain teachings of the Roman Catholic Church of the day. "Sola" is Latin meaning "alone" or "only" and the corresponding phrases are:

• Sola Fide, by faith alone.
• Sola Scriptura, by Scripture alone.
• Solus Christus, through Christ alone.
• Sola Gratia, by grace alone.
• Soli Deo Gloria, glory to God alone.

These phrases may be found individually expressed in the various writings of the 16th century Reformers, either explicitly or implicitly, but they are not found presented as a list per se. It is most likely the list of Solas came about later
