Messiaenism and Messianism

Someone commented on my post about “Messianism in Music” that they expected me to post something by Oliver Messiaen. So here is his Quartet for the End of Time:

And here is his “Alléluias sereins d’une âme qui désire le ciel” which is the second part of his L’Ascension.

Both can also be connected to messianism even without the use of bad puns…
