The new "Mass of the Ages" film released on YouTube on 19 March – and the third in a trilogy about the Latin Mass – is the most moving yet.

“We want to bring back the human, the true, the real,” says the mother of a French priest. "For everything in life…when we deal with a subject without there being an exchange between people, without a connection by the eyes, the voice, the emotion – we can be misled.”

Valerie d’Aubigny, the speaker, was part of a group of elderly mothers – all of whom have sons who are priests – who took it upon themselves to walk the staggering distance of around 1,500 kilometres from Paris to Rome to plead with Pope Francis personally to show mercy and leniency towards Catholics devoted to the ancient rite of the Mass. The women also delivered over 2,500 letters to the Holy Father from the faithful making the same appeal.
