Canon 934. §1 The blessed Eucharist:

1° must be reserved in the cathedral church or its equivalent, in every parish church, and in the church or oratory attached to the house of a religious institute or society of apostolic life

2° may be reserved in a Bishop’s chapel and, by permission of the local Ordinary, in other churches, oratories and chapels.

§2 In sacred places where the blessed Eucharist is reserved there must always be someone who is responsible for it, and as far as possible a priest is to celebrate Mass there at least twice a month.

§1. Sanctissima Eucharistia:

1° asservari debet in ecclesia cathedrali aut eidem aequiparata, in qualibet ecclesia paroeciali necnon in ecclesia vel oratorio domui instituti religiosi aut societatis vitae apostolicae adnexo;

2° asservari potest in sacello Episcopi et, de licentia Ordinarii loci, in aliis ecclesiis, oratoriis et sacellis.

§2. In locis sacris ubi sanctissima Eucharistia asservatur, adesse semper debet qui eius curam habeat et, quantum fieri potest, sacerdos saltem bis in mense Missam ibi celebret.

Canon 935. It is not lawful for anyone to keep the blessed Eucharist in personal custody or to carry it around, unless there is an urgent pastoral need and the prescriptions of the diocesan Bishop are observed.

Nemini licet sanctissimam Eucharistiam apud se retinere aut secum in itinere deferre, nisi necessitate pastorali urgente et servatis Episcopi dioecesani praescriptis.

Canon 936. In a house of a religious institute or other house of piety, the blessed
Eucharist is to be reserved only in the church or principal oratory attached to the house. For a just reason, however, the Ordinary can permit it to be reserved also in another oratory of the same house.

In domo instituti religiosi aliave pia domo, sanctissima Eucharistia asservetur tantummodo in ecclesia aut in oratorio principali domui adnexo; potest tamen iusta de causa Ordinarius permittere, ut etiam in alio oratorio eiusdem domus asservetur.

Canon 937. Unless there is a grave reason to the contrary, a church in which the blessed
Eucharist is reserved is to be open to the faithful for at least some hours every day, so that they can pray before the blessed Sacrament.

Nisi gravis obstet ratio, ecclesia in qua sanctissima Eucharistia asservatur, per aliquot saltem horas cotidie fidelibus pateat, ut coram sanctissimo Sacramento orationi vacare possint.

Canon 938. §1 The blessed Eucharist is to be reserved habitually in only one tabernacle of a church or oratory.

§2 The tabernacle in which the blessed Eucharist is reserved should be sited in a distinguished place in the church or oratory, a place which is conspicuous, suitably adorned and conducive to prayer.

§3 The tabernacle in which the blessed Eucharist is habitually reserved is to be immovable, made of solid and non-transparent material, and so locked as to give the greatest security against any danger of profanation.

§4 For a grave reason, especially at night, it is permitted to reserve the blessed
Eucharist in some other safer place, provided it is fitting.

§5 The person in charge of a church or oratory is to see to it that the key of the tabernacle in which the blessed Eucharist is reserved, is in maximum safe keeping.

§1. Sanctissima Eucharistia habitualiter in uno tantum ecclesiae vel oratorii tabernaculo asservetur.

§2. Tabernaculum, in quo sanctissima Eucharistia asservatur, situm sit in aliqua ecclesiae vel oratorii parte insigni, conspicua, decore ornata, ad orationem apta.

§3. Tabernaculum, in quo habitualiter sanctissima Eucharistia asservatur, sit inamovibile, materia solida non transparenti confectum, et ita clausum ut quam maxime periculum profanationis vitetur.

§4. Gravi de causa, licet sanctissimam Eucharistiam, nocturno praesertim tempore, alio in loco tutiore et decoro asservare.

§5. Qui ecclesiae vel oratorii curam habet, prospiciat ut clavis tabernaculi, in quo sanctissima Eucharistia asservatur, diligentissime custodiatur.

Canon 939. Consecrated hosts, in a quantity sufficient for the needs of the faithful, are to be kept in a pyx or ciborium, and are to be renewed frequently, the older hosts having been duly consumed.

Hostiae consecratae quantitate fidelium necessitatibus sufficienti in pyxide seu vasculo serventur, et frequenter, veteribus rite consumptis, renoventur.

Canon 940. A special lamp is to burn continuously before the tabernacle in which the blessed Eucharist is reserved, to indicate and to honour the presence of Christ.

Coram tabernaculo, in quo sanctissima Eucharistia asservatur, peculiaris perenniter luceat lampas, qua indicetur et honoretur Christi praesentia.

Canon 941. §1 In churches or oratories which are allowed to reserve the blessed
Eucharist, there may be exposition, either with the pyx or with the monstrance, in accordance with the norms prescribed in the liturgical books.

§2 Exposition of the blessed Sacrament may not take place while Mass is being celebrated in the same area of the church or oratory.

§1. In ecclesiis aut oratoriis quibus datum est asservare sanctissimam Eucharistiam, fieri possunt expositiones sive cum pyxide sive cum ostensorio, servatis normis in libris liturgicis praescriptis.

§2. Celebratione Missae durante, ne habeatur in eadem ecclesiae vel oratorii aula sanctissimi Sacramenti expositio.

Canon 942. It is recommended that in these churches or oratories, there is to be each year a solemn exposition of the blessed Sacrament for an appropriate, even if not for a continuous time, so that the local community may more attentively meditate on and adore the eucharistic mystery. This exposition is to take place only if a fitting attendance of the faithful is foreseen, and the prescribed norms are observed.

Commendatur ut in iisdem ecclesiis et oratoriis quotannis fiat sollemnis sanctissimi Sacramenti expositio per congruum tempus, etsi non continuum, protracta, ut communitas localis eucharisticum mysterium impensius meditetur et adoret; huiusmodi tamen expositio fiat tantum si congruus praevideatur fidelium concursus et servatis normis statutis.

Canon 943. The minister of exposition of the blessed Sacrament and of the eucharistic blessing is a priest or deacon. In special circumstances the minister of exposition and deposition alone, but without the blessing, is an acolyte, and extraordinary minister of holy communion, or another person deputed by the local Ordinary, in accordance with the regulations of the diocesan Bishop.

Minister expositionis sanctissimi Sacramenti et benedictionis eucharisticae est sacerdos vel diaconus; in peculiaribus adiunctis, solius expositionis et repositionis, sine tamen benedictione, est acolythus, minister extraordinarius sacrae communionis aliusve ab Ordinario loci deputatus, servatis Episcopi dioecesani praescriptis.

Canon 944. §1 Wherever in the judgement of the diocesan Bishop it can be done, a procession through the streets is to be held, especially on the solemnity of the Body and Blood of Christ, as a public witness of veneration of the blessed Eucharist.

§2 It is for the diocesan Bishop to establish such regulations about processions as will provide for participation in them and for their being carried out in a dignified manner.


§1. Ubi de iudicio Episcopi dioecesani fieri potest, in publicum erga sanctissimam Eucharistiam venerationis testimonium, habeatur, praesertim in sollemnitate Corporis et Sanguinis Christi, processio per vias publicas ducta.

§2. Episcopi dioecesani est de processionibus statuere ordinationes, quibus earum participationi et dignitati prospiciatur.
