Liturgy committee have been around quite awhile. I remember being on the first liturgy committee in the parish I was living in when I was in college. In high school I was part of the school group that helped prepare the ltiurgies. There is a misnomer that liturgy committees plan the liturgies. Liturgy is already planned and spelled out in the liturgical books of the Church. What a committee can do is help coordinate things like lectors, EMHCs, the choirs, ushers, the decorations in the church, etc,
I have taught about forming liturgy committees as part of our diocesan course on liturgy, but the parish I work for, and am liturgy coordinator of, does not have a committee. I honesty do not think it is necessary if there is a person on staff who can coordinate it all. I have contact with all the heads of the lectors, EMHC’s, Family Mass group, enviorment. I prepare for special occasions (like today we are having a Baptism Reunion of all babies baptized in 2008). We used to have a Family Mass COmmittee but once we got the Family Mass all organized and prepared the way the pastor liked it, we didn’t need the committee anymore and I just keep in contact with the coordinator. I also meet with the priests regularly to discuss liturgical matters. I prepare all the presider books, print out all the special blessings or other things that are going to be done at a particular mass (like Feb 1, Boy Scout Sunday, we hand out their religious awards after the Prayer after Communion). During the Triduum, which is my busiest time of the year, the priests know that everything will be totally prepared and all they have to do is look over the books and show up for mass…it make this time of year so much easier for them (although a 70 hour work week for me). A committee might do all this work if they didn’t have someone on staff whose job this is.
Part of the problem with liturgy committees, and it was one of the reasons we dissolved it when I came on board as Pastoral Associate, was that they can become LiturgyNazi’s, demanding that this or that must be done because they heard it at a workshop. I have dealt with one parish where the committee even told the priest which vestments they could wear and which EP he must use. But in situations like that, I blame the pastor for giving the committee the power that they do not possess.
There are times when a committee might come in very handy. Sometimes, I gather the heads of the different liturgical ministries to discuss certain issues. Certainly with the new translations heading our way, if I am still working in this parish (we will be getting a new pastor probably in June of 2010, and, well, who knows what will happen) I will meet with all of them, priests included, to discuss and advise (not dictate) the pastor on how we should proceed with the transition to the new texts.
If your parish does have a committee, and you are asked to be on it, I would begin by totally becoming familiar with the Roman Missal and to read the liturgy documents beginning with the Constitution on the Liturgy and the General Instruction of the Roman Missal. Also, if you come across any liturgical innovations at a workshop or if someone brings it up that they read it in some magazine, search out to see if it is really allowed or if it distracts from the Mass. The Mass has to be prepared well, we don’t need to add to it. Christmas time and Lent is especially a time for committees to add things that don’t belong. like gimmiks and “theme masses.” My kids school was especially fond of these (Patriotic liturgy complete with costumes was the worst).
One thing I need to end with…if your parish liturgy committee seems to be doing something wrong, as I said above, blame the pastor for allowing them to take over the liturgy. He is the chief liturgist of the parish, and sometimes, he may have no clue as to what good liturgy is, and just allows a committee to take over. It is good to arm yourself with documentation as to what should be happening in the liturgy and what should not, but, the pastor does have the final say. If he needs a committee to help prepare liturgies that is fine, but they should be doing the job well and according to liturgical norms, not innovating according to some workshop or article they read.
