And how exquisite was The Lord is My Strength, a duet sung by sopranos Natasha Wilson and Alicia Cadwgan.
These young women were bewitching, their voices achingly beautiful.
This was immediately followed by the choir, their voices rich and full, singing He Is My God and I Will Exalt Him, so passionate and so memorable.
The flute and piano solo Air Sicilien by Gluck, played by the majestic duo David Kelly on piano and Loca Mangi (flute), drifted like a magical dream of love soothing us all.
Soprano Chelsea Dolman was enchanting as she sang Thou Dost Blow With The Wind. Her demeanour was soft and beguiling.
This special choir of young opera voices lifted to the rafters was as glowing as the diffused light streaming through the stained glass windows.
Whanganui, we are truly blessed with these young singers who are all working with passion and dedication at this year's 24th New Zealand Opera School.
And last night they were treated to a special barbecue overlooking the sea - which, I hear, is the perfect way for them to unwind.
Bravo, young singers.
