A friend has sent me the link to a British Pathe film of the external procession at the consecration of the abbey church at Downside in 1935. The officiant and Papal representative was H.E. the Cardinal Prince Primate of Hungary and Archbishop of Esztergom Jusztinián György Serédi OSB, who was formerly a monk of Pannonhalma.
There is a life of the Cardinal at Jusztinián György Serédi
The friend who sent the link commented as to how sharply this contrasts with the recent decision to move away from Downside by the remaining monks. I commented about this decision in September in Downside Abbey and in Downside Abbey - a further thought
Three years beforehand in 1932 the rebuilt church of the abbey at Buckfast had also been consecrated and the sense that monastic life had a certainty and a future in this country must have been strong, as is indeed suggested in the film commentary.
