From a reader:
In my parish there is offered both the TLM or EF and the NO. Sometimes parishioners who almost exclusively attend the NO come to the TLM (which is a great thing, praise God and Vivat Papa!) . However, often these members of the faithful import customs from the NO, post particularly they approach the communion rail with arms folded and expect a blessing (which, because our holy priest is very charitable and not particularly traditional, they receive). They also sometimes insist on saying the Oratio Dominica [For people in Columbia Heights that's the Lord's Prayer.] with the priest and (I digress a little now) wear clothing that unfortunately is not out of place at a NO Mass, but is very much so – and even offensive, at a TLM.
Can I do anything to stop these things while exercising charity to stop these things which are distractions to me and other members of the faithful, and which Mother Church in her infinite wisdom does not deem part of a TLM?
Perhaps, friend, you need to worry about other things.
If the priest wants to give the blessings at Communion, that is not part of Mass but neither is it the end of the world. We are in a time of transition. I am also reminded of the parable in which some workers are resentful that others who didn’t work as long are getting a wage for a day. But I digress…. Let the priest deal with these things, perhaps in sermons, announcements given during Mass, or bulletin notes.
About the Lord’s Prayer: Pope’s Pius IX and Pius XII indicated that the congregation could say the Lord’s Prayer together with the priest. This was long in place before the 1962 Missale Romanum. It is one aspect of participation at Mass from before the book we use for the Extraordinary Form you may not prefer it, but don’t say it has nothing to do with the Extraordinary Form. It does. I know that some people who prefer the TLM don’t like that. Sorry. Again, let the priest guide the development of the local customs and application of the provisions of Summorum Pontificum.
Also, while somethings are distracting to you, other things are distracting to the new comers. For example, not saying the Lord’s Prayer and not receiving a blessing, when all their lives they have been doing these things, is a matter of real distraction.
I would let things be and not worry about them too much. Life is sometimes messy. New blood coming to the parish is good. People figuring out the lay of the land on their own without coercion and then changing their ways to fit in is a good thing.
