As far as poetic Romantic music goes, try Hugo Wolf's settings of Goethe!
The most spiritually poetic music for me personally is J. S. Bach's St. Matthew Passion. Also, Anton Webern's symphony is one of the most spiritual pieces of music I have ever heard or studied; neither of these in a Romantic sense however! More in a crystalline structural sense.
Not all poetic music need be Romantic!

I've only seriously sat down to listen to Wolf again. Where song is central to Schubert... and the music and the accompaniment are at least equal to the lyrics... Wolf demands that you follow the text closely as the text truly dictate... inspires the music.
