So, I was doing a bit of research on the phrase soli deo gloria and found this out, it is pretty interesting. Maybe you will think so too. If only my wrist was bigger-get it;)
There are actually 5 solas, they are:
sola scriptura::scripture alone
sola gratia::grace alone
sola fide::faith alone
solus christus::Christ alone
soli deo gloria::to God alone be the glory
the five solas is a term used to designate the five great foundational rallying cries of the Protestant reformers. They were developed in response to the specific perversions of the truth that were taught by the corrupt Roman Catholic Church. The Roman church taught that the foundation for faith and practice was a combination of the scriptures, sacred tradition and the teaching of the magisterium and the pope; but the reformers said, "No our foundation is sola scriptura." The Catholic church taught that we are saved through a combination of Gods grace, the merits that we accumulate through penance and good works, and the superfluity of merits that the saints before us accumulated; the reformers responded, "sola gratia." The Catholic Church taught that we are justified through faith and the works we produce, which the righteousness that God infuses in us through faith brings about. The reformers responded, "No we are justified by faith alone." The Catholic church taught that we are saved by the merits of Christ and the saints, and that we approach God through Christ, the saints, and mary who all pray and intercede for us. The reformers responded, "No we are saved by the merits of Christ alone and we come to God through Christ alone." The Catholic church adhered to what Martin Luther called the theology of glory (in opposition on the theology of the cross) in which the glory for a sinner's salvation could be attributed partly to Christ, partly to mary and the saints and partly to the sinner himself. The reformers responded, "No, the only true gospel is that which gives all the glory to God alone, as is taught in the scriptures."
