Christ's Faithful People
|253. For the celebration of the eucharist, the people of God normally assemble in a
church or, if there is none, in some other fitting place worthy of so great a mystery.
Churches and other places of worship should therefore be suited to celebrating the liturgy
and to ensuring the active participation of the faithful. Further, the places and
requisites for worship should be truly worthy and beautiful, signs and symbols of heavenly
254. At all times, therefore, the Church seeks out the service of the arts and welcomes the artistic expressions of all peoples and regions. The Church is intent on keeping the works of art and the treasures handed down from the past  and, when necessary, on adapting them to new needs. It strives as well to promote new works of art that appeal to the contemporary mentality. 
In commissioning artists and choosing works of art that are to become part of a church, the highest artistic standard is therefore to be set, in order that art may aid faith and devotion and be true to the reality it is to symbolize and the purpose it is to serve.
255. It is preferable that churches be solemnly consecrated. The faithful should give due honor to the cathedral of their diocese and to their own church as symbols of the spiritual Church that their Christian vocation commits them to build up and extend.
256. All who are involved in the construction, restoration, and remodeling of churches are to consult the diocesan commission on liturgy and art. The local Ordinary is to use the counsel and help of this commission whenever it comes to laying down norms on this matter, approving plans for new buildings, and making decisions on the more important issues.
|257. The people of
God assembled at Mass possess an organic and hierarchical structure, expressed by the
various ministries and actions for each part of the celebration. The general plan of the
sacred edifice should be such that in some way it conveys the image of the gathered
assembly. It should also allow the participants to take the place most appropriate to them
and assist all to carry out their individual functions properly.
The congregation and the choir should have a place that facilitates their active participation.
The priest and his ministers have their place in the sanctuary, that is, in the part of the church that brings out their distinctive role, namely, to preside over the prayers, to proclaim the word of God, or to minister at the altar.
Even though these elements must express a hierarchical arrangement and the diversity of offices, they should at the same time form a complete and organic unity, clearly expressive of the unity of the entire holy people. The character and beauty of the place and all its appointments should foster devotion and show the holiness of the mysteries celebrated there.
|258. The sanctuary should be clearly marked off from the body of the church either by being somewhat elevated or by its distinctive design and appointments. It should be large enough to accommodate all the rites. |
|259. At the altar the sacrifice of the cross is made
present under sacramental signs. It is also the table of the Lord and the people of God
are called together to share in it. The altar is, as well, the center of the thanksgiving
that the eucharist accomplishes. 
260. In a place of worship, the celebration of the eucharist must be on an altar, either fixed or movable. Outside a place of worship, especially if the celebration is only for a single occasion, a suitable table may be used, but always with a cloth and corporal.
261. A fixed altar is one attached to the floor so that it cannot be moved; a movable altar is one that can be transferred from place to place.
262. The main altar should be freestanding to allow the ministers to walk around it easily and Mass to be celebrated facing the people. It should be so placed as to be a focal point on which the attention of the whole congregation centers naturally. The main altar should ordinarily be a fixed, consecrated altar. 263. According to the Church's traditional practice and the altar's symbolism, the table of a fixed altar should be of stone and indeed of natural stone. But at the discretion of the conference of bishops some other solid, becoming, and well-crafted material may be used.
The pedestal or base of the table may be of any sort of material, as long as it is becoming and solid.
264. A movable altar may be constructed of any becoming, solid material suited to liturgical use, according to the traditions and customs of different regions.265. Altars both fixed and movable are consecrated according to the rite described in the liturgical books; but movable altars may simply be blessed. There is no obligation to have a consecrated stone in a movable altar or on the table where the eucharist is celebrated outside a place of worship (see no. 260).
266. It is fitting to maintain the practice of enclosing in the altar or of placing under the altar relics of saints, even of nonmartyrs. Care must be taken to have solid evidence of the authenticity of such relics.
267. Minor altars should be fewer in number. In new churches they should be placed in chapels separated in some way from the body of the church.
|268. At least one cloth should be placed on the altar
out of reverence for the celebration of the memorial of the Lord and the banquet that
gives us his body and blood. The shape, size, and decoration of the altar cloth should be
in keeping with the design of the altar. 269. Candles are to be used
at every liturgical service as a sign of reverence and festiveness. The candlesticks are
to be placed either on or around the altar in a way suited to the design of the altar and
the sanctuary. Everything is to be well balanced and must not interfere with the
faithful's clear view of what goes on at the altar or is placed on it.
270. There is also to be a cross, clearly visible to the congregation, either on the altar or near it.
|271. The priest celebrant's chair ought to stand as a symbol of his office of presiding over the assembly and of directing prayer. Thus the best place for the chair is at the back of the sanctuary and turned toward the congregation, unless the structure or other circumstances are an obstacle (for example, if too great a distance would interfere with communication between the priest and people). Anything resembling a throne is to be avoided. The seats for the ministers should be so placed in the sanctuary that they can readily carry out their appointed functions. |
|272. The dignity of
the word of God requires the church to have a place that is suitable for proclamation of
the word and is a natural focal point for the people during the liturgy of the word. 
As a rule the lectern or ambo should be stationary, not simply a movable stand. In keeping with the structure of each church, it must be so placed that the ministers may be easily seen and heard by the faithful.
The readings, responsorial psalm, and the Easter Proclamation (Exsultet) are proclaimed from the lectern; it may be used also for the homily and general intercessions (prayer of the faithful).
It is better for the commentator, cantor, or choir director not to use the lectern.
|273. The places for
the faithful should be arranged with care so that the people are able to take their
rightful part in the celebration visually and mentally. As a rule, there should be benches
or chairs for their use. But the custom of reserving seats for private persons must be
abolished.  Chairs or benches should be set up in such a way that the
people can easily take the positions required during various celebrations and have
unimpeded access to receive communion.
The congregation must be enabled not only to see the priest and the other ministers but also, with the aid of modern sound equipment, to hear them without difficulty.
|274. In relation to the design of each church, the schola
cantorum should be so placed that its character as a part of the assembly of the
faithful that has a special function stands out clearly. The location should also assist
the choir's liturgical ministry and readily allow each member complete, that is,
sacramental participation in the Mass. 
275. The organ and other lawfully approved musical instruments are to be placed suitably in such a way that they can sustain the singing of the choir and congregation and be heard with ease when they are played alone.
|276. Every encouragement should be given to the
practice of eucharistic reservation in a chapel suited to the faithful's private adoration
and prayer.  If this is impossible because of the structure of the church,
the sacrament should be reserved at an altar or elsewhere, in keeping with local custom,
and in a part of the church that is worthy and properly adorned. 
277. The eucharist is to be reserved in a single, solid, unbreakable tabernacle. Thus as a rule there should be only one tabernacle in each church.
|278. In keeping with the Church's very ancient tradition, it is lawful to set up in places of worship images of Christ, Mary, and the saints for veneration by the faithful. But there is need both to limit their number and to situate them in such a way that they do not distract the people's attention from the celebration.  There is to be only one image of any one saint. In general, the devotion of the entire community is to be the criterion regarding images in the adornment and arrangement of a church.|
|279. The style in which a church is decorated should
be a means to achieve noble simplicity, not ostentation. The choice of materials for
church appointments must be marked by concern for genuineness and by the intent to foster
instruction of the faithful and the dignity of the place of worship.
280. Proper planning of a church and its surroundings that meets contemporary needs requires attention not only to the elements belonging directly to liturgical services but also to those facilities for the comfort of the people that are usual in places of public gatherings.
