Yes, thank you for that.
I'm glad that your parish has decided to have one Liturgy for everyone. There is a similar phenomenon in the Church of England, where there is often a quiet "8 o' clock" Mass according to the 1662 rite, and then another later in the morning, which is the main one, for the Common Worship rite. I think that this arrangement serves to divide the community, and it is much better if everybody goes to the same one.
The differences of language are neither here nor there, as God is being worshipped anyway. This reminds me of the anecdote of a very Anglo-Catholic priest filling in for a colleague of his, who was on holiday. This church was rather more protestant than the visiting priest had been accustomed to, and so the congregation didn't respond well to his Latin Mass. He was approached by one of the congregation after the Mass, who said, reprimandingly, "Father, I didn't understand a word of that service!", to which the priest replied "Well, I wasn't talking to you".
Is it not the case that not only may the Liturgy not be served more than once per day on any altar, but also that no priest may serve the Liturgy more than once per day? Is this rule dispensable at the discretion of the bishop?
