The Vestments
The Ministers at Mass do not just wander randomly into their places and then Mass starts. While the Entrance Chant is being sung, there is a procession of the ministers through the church and into the sanctuary. Please note the terminology: the church is the building; the sanctuary is the place in the church where most of the activities of the Mass take place; the altar is the table in the sanctuary where the Sacrifice of the Mass is offered. These terms are not interchangeable. People often ask if they are to be in the sanctuary, “Do you want me on the altar.” I often reply, “No, you’ll kick over the chalice.” (You see why I don’t get invited to parties.)
The General Instruction of the Roman Missal instructs regarding the procession:
When the people are gathered, the Priest and ministers, wearing the sacred vestments, go in procession to the altar in this order:
a) the thurifer carrying a smoking thurible, if incense is being used;
b) ministers who carry lighted candles, and between them an acolyte or other minister with the cross;
c) the acolytes and the other ministers;
d) a reader, who may carry a Book of the Gospels (though not a Lectionary), slightly elevated;
e) the Priest who is to celebrate the Mass. (n. 120)
The first line tells us that the priest and the ministers are “wearing the sacred vestments.” Vestments are not just fancy clothing for the sake of fancy clothing. The Priest is told that the vestments should cover his “street clothes.” This is not just a silly stipulation. The vestments are another sign that the priest and deacon are not just their usual selves at Mass. The priest wears clothes that he doesn’t wear anywhere else to show that his roles at Mass is different than when you see him in his office or at the store. The priest is acting in persona Christi, meaning that he is in the place of Christ at the Mass. He is the one acting in the place of Christ, offering the act of the Mass to God the Father.
The vestments the priest wears:
The alb (from the Latin for white, albus--without the Dumbledore!) is the long white garment that is the clothing of all the baptized, not just the priest.
As mentioned earlier, if the alb does not cover the priest’s street clothes at the neck, an amice is used. This is a rectangular cloth with cloth cords that wraps around the priest’s neck and ties off in the front.
The alb may be tied off with a cincture, a cord that wraps around the waist. (I think that since being ordained a deacon, I have only not worn the cincture about 5 times, and that was only because I forgot mine and one could not be found).
The priest then puts on the stole, the cloth band that hangs around his neck. This is a sign of his priestly authority, so it is also worn for things like confessions, baptisms, blessings, etc. This is worn with the ends hanging down in front of him.
The chasuble (from casula Latin for “little house”) it the poncho-like vestment that the priest wears over the rest of the vestments. This vestment is used only at Mass.
The deacon wears the vestments except he wears the stole over his left shoulder and crossing over his chest and tied off at the right side. The deacon also wears, in place of the chasuble, the dalmatic, a more square-cut vestment with sleeves.
Bonus material: Over the years, the vestments have also taken on symbolic meanings, as reflected in the optional prayers (below in italics) to be said while vesting.
The amice represents the helmet of salvation and a sign of resistance against temptation (note: the priest usually kisses it and passes it over his head before putting it across his shoulders and tying it around the waist.) Place, O Lord, on my head the helmet of salvation, that I may overcome the assaults of the devil.
The alb, signifies perfect integrity. Purify me, O Lord, from all stain and cleanse my heart, that, washed in the Blood of the Lamb, I may enjoy eternal delights.
The cincture symbolizes the virtue of purity. Gird me, O Lord, with the cincture of purity, and quench in my heart the fire of concupiscence, that the virtue of continence and chastity may remain in me.
The stole is a symbol of immortality and the sign of the dignity of the ministerial priesthood. Restore to me, O Lord, the state of immortality which was lost to me by my first parents, and, although unworthy to approach your sacred mysteries, grant me, nevertheless, eternal joy.
The chasuble is the emblem of charity which makes the yoke of Christ light and agreeable. O Lord, you said, “My yoke is sweet and my burden light,” grant that I may carry it so as to obtain your grace. Amen.
