Right. I have answered my own question. The German anthem was composed at the end of the 18th century by Haydn. "Ein feste Burg..." is Luther's Hymn. From what I have just read, the super-nationalist verses ("Deutschland über Alles...") have simply been dropped, and only the third verse, which speaks of unity, justice, and freedom is sung. Good idea, to preserve a great melody and skip the nationalist sentiments.
