Fr. Ray Blake points to instructional videos on how to say Mass in the extraordinary form, available on YouTube.

After remarking that regular observation and practice have made him reasonably competent in celebrating the Traditional Latin Mass, he writes,

What I am not quite certain about and what other priests and bishops seem equally confused about is how to celebrate Mass according to the Ordinary Form.

No-one seems to know what should [be] normative there, nor how to choose from the vast number of options. Someone said recently[:] from Brompton Oratory to the diocese of Linz we experience the variety of interpretations of the Roman Missal. Are all correct?
