I am trying to find a book or something that shows a layout of the Catholic Church and all the proper names for the places in it.
After the Mass today, I went up to the front of the church where there appears to be what’s called a Communion Rail, except at this church they dont use it for communion. Behind that area is of course the altar, and facing it to your left is the choir area. To the right is Mary and to the right of her, off to the side is the tabernacle with the red candle where the people go to get the Eucharist out of it, to give to the people. The names for these people, I don’t know so I’ll just call them assistants for now.
These “assistants” are called "Extraordinary Ministers of Holy Communion." The word “Extraordinary” is used because the Ordinary Minister is the Priest. Extraordinary Ministers are used when there are not enough priests to distribute Holy Communion.
There is a room behind this tabernacle area that they keep the door open to, where the priest comes out at the beggining of the Mass, with the altar boys and girls, and some other people (I dont know what they would be called either)
The room is called the Sacristy. There are usually closets which hold the priestly vestments, and cabinets which hold different chalices, patens (the plates that hold the consecrated bread - Holy Communion), and other things needed for Mass.
This is where the priests puts on his vestments, the altar servants put on their white albs, and everybody who is ministering at the Mass gets ready.
The people who would process out with the priest would be the Altar Servers, the Extraordinary Ministers of Holy Communion, and the Lector (the man or woman who reads the first two readings and sometimes the psalm in between the first two readings - sometimes the choir sings the psalm instead).
and then they go around the back, and then up the center aisle to the front area I described.
. . .
She told me she would be happy to help me out if I needed it, and told me to call her anytime.
**And I think you should call her. Make an appointment to sit down and have a chat with her. (She probably has an office in one of the parish buildings.) Tell her what you’ve told us, that you’re not Catholic, but are interested. You can join the RCIA (Rite of Christian Initiation for Adults) which is how people learn to become Catholic. Of course, if after going through RCIA you change your mind, or need more time, don’t feel pressured. (But the Catholic Church is great and I think you’ll really love it and come to see that it truly holds the fullness of faith.

)
While you are talking with her, you can bring up the subject of what went on after Mass. One charitable way of doing it may be to say something like, “I had thought that it was disrespectful to answer the phone, chitchat, or to walk back in forth in front of the Tabernacle. I know I don’t know much of anything about being Catholic, was I wrong?” This will take the emphasis off of her so she won’t get all defensive, because you are presenting yourself as one trying to learn. It will also cause her to think twice the next time she’s in the presence of the Blessed Sacrament.
