LOS ANGELES — What’s the only art form big enough to hold Kanye West’s grandiosity, his grievances, his cast-of-thousands collaborations, his musical lushness and toughness, his religiosity, his self-appointed skill at design? Has anyone in music — has anyone, ever — been so operatic?

But being an operatic person doesn’t mean you’ll create a good opera. And “Nebuchadnezzar,” the passionate, puzzling work West billed as an opera — announced on Nov. 17 and performed at the Hollywood Bowl just seven days later, on Sunday — wasn’t really an opera, and it wasn’t really good.

What it was, more or less, was another of this year’s loud declarations of West’s born-again bona fides. Sitting off to the side of the stage and speaking with inflamed urgency, he read passages from the biblical Book of Daniel — the story of a mad king who finds God — as an enormous gospel choir milled around in pale gowns and wailed phrases in Latin.

This was Sunday Service, the group West has been presenting in church-like performances since January — mainly in Calabasas, Calif., but also at Coachella and elsewhere — in which he has tended to recede from the spotlight, more ringleader than performer. The group was also featured, to earbud-popping effect, on West’s ninth album, “Jesus Is King,” released last month, and is said to be central to his next, “Jesus Is Born,” scheduled for, yes, Christmas.
