The Procession
The procession approaches the sanctuary and the ministers make a sign of reverence (a genuflection to the tabernacle or a bow to the altar, if the tabernacle is not in the sanctuary).
The altar is the table in the sanctuary where the consecration takes place. The altar is a symbol for Christ. This is why the priest and the deacon kiss the altar at the beginning of Mass. The altar can be fixed, where it is secured to the floor, or movable. Our altar in the Church is fixed, the one in the chapel is movable. The ideal is that at least the flat top of the altar be stone, but other “noble and solid material suited to liturgical use” (GIRM 301) may be used.
The altar is consecrated for use (though a movable one can be only blessed), usually by the Bishop, but he can delegate the dedication to a priest. In the Rite of the Dedication of an Altar, the altar is anointed with Chrism and burning incense is placed on the altar to symbolize the prayers offered at the altar. (It is also reminiscent of the dedication of the altar in Exodus chapter 40).
It has been the custom of the church to place the relics of saints into an altar. This harkens back to the earliest days of the Church when the Church gathered over the tombs of the martyrs to celebrate the Mass. The GIRM warns, “However, care should be taken to ensure the authenticity of such relics.” I guess my feather from the wing of St. Michael is out.
The altar is to be covered with a white cloth—at least on top; additional other colors may be used, but the top cloth is always white. Candlesticks are to be placed on or around the altar. This is another of those places where the practical has become liturgical; in days past, candles would have been needed for light, but now have a special relationship to the altar, which symbolizes Christ the Light. There is to be a crucifix on or near the altar.
Flowers may be placed around—not on—the altar. There are to be no flowers during Lent, except for the 4th Sunday (Laetare Sunday). There should be a difference between the decorations of Advent and those of Christmas (I can’t say I’ve seen a church where this has gotten confused!) Even for Christmas and Easter, moderation is called for. If you can’t see the altar because of the flowers, something isn’t right.
The one carrying the Book of the Gospels--the deacon if present, a reader if the deacon is not--places the Book of the Gospels on the altar. The priest and the deacon venerate the altar with a kiss.
The altar may be incensed. The priest adds incense to the thurible, aka censor, blesses it silently and then walks around the altar, returning the thurible to the deacon, who gives it to the server. (There will be more on incense and its use in a future column).
After that, the priest goes to the presider’s chair, which signifies the Priest Celebrant’s function of presiding over the gathering and of directing the prayer (there is only one presider, even if several priests are con-celebrating). Because of the Presider’s role, his chair is not to be one-among-others in the congregation, as has been mistakenly done in some places; his chair is to be prominent and visible in the place from which he leads the liturgy.
