Others more knowledgeable than I have explained what is necessary for a Mass to be invalid in this thread:
forums.catholic-questions.org/showthread.php?t=405478 Please read through it–it’s very interesting.
Although some of the actions that were raised in the OP were objectionable, they apparently didn’t affect the validity of the Mass.
Although bpbasilphx seems to be making the OP upset, he makes some excellent points. Of course, we should be concerned and upset when things in the Mass appear awry or disrespectful. But as bpbasilphx keeps saying, we should not label these things “liturgically abusive” or assume that the Mass is invalid
until we have searched the Church documents and/or asked an expert. A lot of things done in Masses are not what we are used to or what we personally prefer, but they are still liturgically correct and perfectly valid.
Finally, I’ll repeat what I said a few posts ago–it appears that the OP has taken the suggestions of several people in this thread and has decided on a simple letter to the bishop rather than making a public showing of objections. I personally think that the OP has made a wise and charitable decision and hope that the letter brings about any necessary corrections in the Masses without causing scandal or hurt.
