Susan asked for this one: Christ Shall Have Dominion. If It sounds like Onward, Christian Soldiers, it’s because both lyrics use the same melody by Arthur S. Sullivan of Gilbert & Sullivan fame, published in 1871. It doesn’t have to be fancy–three friends, a guitar, and a couple of hymnals will do the trick.
The first time I posted this hymn, somebody complained. I replied, “Well, then, who would you rather have dominion, other than Jesus Christ?” I never got an answer.
