From ReformedWiki.org, the wiki for Reformed Christianity
The Five Solas of the Protestant Reformation unites all protestant reformers on salvation (in opposition to the official teachings of the Roman Catholic Church), which are: sola scriptura (Scripture alone), solus Christus (Christ alone), sola fide (faith alone), sola gratia (grace alone), and soli Deo gloria (glory to God alone).
