The first complete Mass entirely in the Cornish language (Kernewek), known as Oferen an Dasserghyans (the Mass of the Resurrection), was premiered at Truro Cathedral on June 3, 2026. [1, 2, 3, 4]
The landmark service coincided with the Eve of the Feast of St Petroc, one of Cornwall’s patron saints. Here are the key details about this historic event: [1]
- The Music & Language: The Mass was composed by Mike O’Connor, using traditional Cornish folk song tunes designed for easy congregational singing rather than just trained choirs. It was developed by a team including the Rev Jane Kneebone (Gorsedh Chaplain), poet Tim Saunders, and linguist Wella Brown. [1, 2, 3, 4]
- Service Materials: Alongside the Cornish text, full English translations were provided so both fluent speakers and those with no prior knowledge of the language could participate. [1]
- Where to Watch: The historic Sung Eucharist was recorded and is available to watch on the Truro Cathedral YouTube Channel. [1, 2]
