What you might want to do is to start with reading the authoritaitve documents of the Church on all matters regarding the Holy Sacrifice of the Mass. The General Instruction of the Roman Missal (3rd typical edition-2002-USCCB) is essential reading. However, it should be read in tandem with Redemptionis Sacramentum which details liturgical abuse. Sacramentum Caritatis is also an excellent document to read as well. You can find these at
www.adoremus.org . In fact, you can find a lot of liturgical information on this website. They have an excellent online liturgical library.
It would not be a bad idea for the Knights to engage in some sort of liturgical training once a month during your meetings (or, hold a special meeting to look at the matter apart from your regular meeting). Since your council is a parish one, this is one way that your pastor can be directly involved since I assume he is also your chaplain.
The GIRM gives you the particulars such as EMHCs not approaching the altar until after the celebrant has communicated (this also means that they cannot go to the tabernacle, as this is reserved to the celebrant). Lectors should also be trained as to the manner of proclaiming the readings.
Insofar as music is concerned, it is helpful to read Musicam Sacram, the Church’s authoritative document on the music. Don’t necessarily go by what the publishing houses suggest because, more often than not, they will promote their own music rather than what the Church considers to be sacred.
One way to put what you have learned into practice would be in November when the Knights typically have their Memorial Mass for their deceased brethren. There, since y’all will help plan the Mass, you can certainly introduce chant and sacred music. The only suggestion that I will make (and I have made it to my father, since he is a fourth degree knight) is that you defer the traditional “roll call” until after the post-Communion prayer, since this is not part of the Mass, per se.
If I may, I will offer one more suggestion. One way that your council can be of help to the entire parish as a whole is to perhaps help sponsor a workshop or help secure materials on catechizing your parishioners on the revised translation of the Roman Missal. The prayers have been revised and you would serve your parish well if you could help facilitate this. This, I believe, is a key factor to help iimprove the liturgical life of your parish. The prayers have been revised to use a more sacred, elevated language. This means that the Mass settings are going to change as well, to reflect these revisions.
