There is a difference between a mistake and abuse. God knows we are all only human, even priests. But an abuse is an intentional disregard for liturgical law.IMO, this approach would lead to pride. I would see myself as “better than all the other people sitting in Mass because I know more than they do.”
I am not a cop. I am a parishioner, and the priest is my father. He knows more than I do. My bishop knows more than my priests do.
I know that some of you must live in hell here on earth. I can honestly say that out of all the parishes that I have visited in my diocese, and all that I have visited in three states (Illinois, Missouri,and Michigan), I have never seen an “abuse.” Errors, yes. (A few weeks ago, I was playing at a wedding, and the priest totally bungled the Liturgy. Afterwards, he apologized to the musicians and explained that he was distracted by the antics and screams of the four little flower girls who decided that the sanctuary was a gymnasium! Their mothers were the bridesmaids, so no one was available to take these little girls out and calm them down. Poor priest!)
But I am willing to overlook errors. I make plenty myself.
The reason people are very particular about proper liturgy is the principle of “lex orandi, lex credendi”. We are not talking about mistakes, we are talking about abuse. What you describe is not abuse, it’s a mistake.
But I must disagree; there are priests who indeed DO NOT KNOW what they ought. That is a sad fact, and many of these priests are humble enough to try and receive further education from LAITY.
This has nothing to do with pride. This has everything to do with the Catholic in the pew knowing his liturgy by heart, the rights he has granted by the Holy See itself, and the means and time to assert those rights.
Redemptionis Sacramentum is a very easy read. Why not get a copy and check it out with the GIRM. At the back of RS are the gravity of abuse and what the laity’s responsibilities are about them.
The liturgy belongs to the Church, not to the priest, and not to the laity, but to the Church. No one has the right to mess with it.
