Please forgive me for being a theology nerd and classical music junkie here. Music is a great source of joy to me, as is my faith. When the two coincide, the fireworks start! I hope this post helps you to find joy in either or both of them…

Mozart died when he was just 35 years old, having written more than 800 pieces of music. He wrote his « Great » mass in C minor, the last of his 17 masses (17?!), when he was just 27 years old. It is a really extraordinary work. I want to share two glorious movements from it, the first one in this blog, the second in the next.
The first is the Domine Deus from the Gloria (the 5th movement), which is just 2 mins 44 seconds long in this excellent recording, but in which things of eternal theological consequence happen:
I’m going to run through this using timings, so you can identify the moments I am referring to. If you read music you might find the score in the video helpful/revealing! (But you don’t need to be able to read music to understand what I will share.)
Here is the text and translation:
Latin text: Domine Deus, Rex coelestis, Deus Pater omnipotens.
Domine Fili unigenite, Jesu Christe. Domine Deus, Agnus Dei, Filius Patris.
English translation: Lord God, King of the heavens, God the Father Almighty. (NB 👈🏼 this all refers to God the Father.)
Lord only-begotten Son, Jesus Christ. Lord God, Lamb of God, Son of the Father. (NB 👈🏼 this all refers to God the Son ie Jesus.)
0:21 the first voice comes in with « Domine Deus… » all the text about God the Father
0:42 the second voice follows with a tiny overlap with « Domine Fili… » all the text about God the Son
1:07 each voice takes the part of the Father or the Son and they sing in harmony, the two sets of words at the same time.
1:29 the two voices sing the words for God the Father together in harmony and then the words for God the Son together in harmony at the same time. Which to me symbolises God the Father and God the Son being one in heaven.
THEN…
1:48 is one of my favourite moments in this piece… can you hear when Filius (God the Son) descends from Patris (God the Father)? See if you can tell the moment when one voice descends from the other. It is tricky to hear because the performers are so good. The intention is for the Son to seamlessly emerge from the Father. Then they both sing « Filius Patris » « Son of the Father » in such a way that Filius and Patris interweave constantly.
To me, 1:48 represents the moment of incarnation, when Jesus (the Son of God) was born in human form, which Christians celebrate particularly at Christmas. As far as I know, no other religion has this story of God becoming human while still remaining God. It is an extraordinary, inexplicable paradox, here represented beautifully in music. In Christian language we describe it as God the Son (Jesus) being sent by God the Father. Both are in fact the King of the heavens and are God. They are One, and yet when Jesus was born on earth somehow their Oneness was stretched as far as it could be without reaching breaking point (for interesting theological insight on this the work of Jürgen Moltmann is a must. But only if you are a theology nerd as his writing is quite dense!).
AND THEN… (yes, there’s more!)
2:12 is my favourite moment in this whole movement, when Patris (God the Father) and Agnus Dei (the lamb of God – ie the Son) seamlessly echo one another’s glorious voice, as the sopranos take turns with these beautiful, soaring, sustained high notes. Again, see if you can detect the slight change of timbre as they swap the same high notes between the two voices. With good performers such as these, it’s very tricky to hear the difference, unless you’re at a live performance and can see when each takes a turn with the high notes by watching their body language. It sends shivers down my spine just hearing it again.
God the Father and God the Son; One voice, the voice of love that would always, always come down in tangible human form, to bring the miraculous possibility of something new; of joy. May this joy of miraculous possibility be yours today, whatever you are facing. 🙏🎵❤️
