Chorus: “Christ shall have dominion over land and sea, Earth’s remotest regions shall His empire be.” Sing it out, sing it loud. You already know the tune. It’s “Onward, Christian Soldiers,” both hymns using the melody composed by Arthur Sullivan, published in 1871. It’s the same Sullivan of Gilbert & Sullivan fame.
Sung here by the congregation at the First OPC in Perkasie, Pennsylvania.
