Looking at some of the suggestions here it seems as if we are required to stay strictly to "oratorios" but any larger choral piece. Among my favorites I would surely include:

1. Bach- St. Matthew Passion
2. Bach- St. John Passion (unjustly ignored)
3. Haydn- The Creation
4. Beethoven- Missa Solemnis
5. Brahms- Deutsches Requiem
6. Mozart- Requiem
7. Mozart- Mass in C
8. Faure- Requiem
9. Verdi- Requiem
10. Handel- Messiah

... but that's just a start... I'm such a huge fan of choral music I wouldn't know where to end.
