The song "O Divine Redeemer" by Charles Gounod is one of the most beloved pieces of sacred vocal music ever written. I have played this numerous times, accompanying both soloists and choirs. I found an interesting article about it by the LDS organist James Welch. He gives some background about the composer and his music, and the history of "O Divine Redeemer." He includes a literal translation of the original French, and ends with some comments of how it is been used in the LDS church.
