Soli Deo gloria
Soli Deo gloria is a Latin term for Glory to God alone. It has been used by artists like Johann Sebastian Bach, George Frideric Handel and Christoph Graupner to give God credit for their work. The phrase has become one of the five solas propounded to summarise the Reformers' basic beliefs during the Protestant Reformation.
As a doctrine, it means essentially that everything that is done is for God's glory to the exclusion of humankind's self-glorification and pride. Christians are to be motivated and inspired by God's glory and not their own.
The three words S.D.G. have meanings in Latin as follows: soli is the (irregular) dative singular of the adjective "lone", "sole", and agrees with the dative singular Deo, (in the nominative dictionary form Deus), meaning "to God"; and gloria is the nominative case of "glory".
Soli Deo gloria is usually translated glory to God alone, but some translate it glory to the only God. A similar phrase is found in the Vulgate translation of the Bible: "soli Deo honor et gloria". This is grammatically the same as the signature of Bach and Handel, but using the dative "to the only God" then two nominative subjects "honour and glory." The verse reads differently in Greek and English because of the additional adjective "wise" aphthartoi, aoratoi, monoi, sophoi Theoi "to the immortal, invisible, unique, wise, God."
Musical and literary usage
The Baroque composer Johann Sebastian Bach wrote the initials "S. D. G." at the beginning and end of all his church composition and also applied it to some, but not all, his secular works. This dedication was at times also used by Bach's contemporary George Frideric Handel, e.g. in his Te Deum. The 16th century Spanish mystic and poet St. John of the Cross used the similar phrase, Soli Deo honor et gloria, in his Precautions and Counsels.
Protestant usage in the Five Solas
Together with sola fide, sola gratia, sola scriptura and solus Christus, the phrase has become part of what is known as the Five Solas, a summary statement of central tenets of the Protestant Reformation. Although these individual phrases have been used for centuries, it is not clear when they were first put together.
Other denominational views
In Eastern Orthodox and Roman Catholic theology, the term latria is used for the form of adoration and glorification directed only to the Holy Trinity. The term dulia is used for saints in general and hyperdulia (below latria) for the Virgin Mary. The definition of the three level hierarchy of latria, hyperdulia and dulia goes back to the Second Council of Nicaea in 787.
