Soli Deo Gloria
(Glory to God Alone)
Each of the great solas is summed up in the fifth Reformation motto: soli Deo gloria, meaning to God alone be the glory. It is what the apostle Paul expressed in Romans 11:36 when he wrote, “to Him be the glory forever! Amen.”These words follow naturally from the preceding words, “For from him and through him and to him are all things” (v. 36), since it is because all things really are from God, and to God, that we say, “to God alone be the glory.”
