I'm looking for the purist translation of , "God, alone," such as in the seven sola's of the Reformation. I see "soli deo" a lot, however, many seem to say that "sola dei" is more correct and exact. So, I'm a bit confused, and need an explanation. In a broader sense, would either be acceptable? My intention is to use this phase as a title for my business. I realize that "gratia" would complete the phrase as it's used historically, but prefer two words. Thank you for any input!
