This is from canon law. It doesn’t anticipate having people keep the Eucharist in their homes. There is an emphasis on having the Eucharist in a church, kept secure in a tabernacle, marked by a lamp, etc. Take a look at canon 935 – I wonder if the priest considers this a “pastoral necessity.”
THE RESERVATION AND VENERATION OF THE MOST HOLY EUCHARIST
Can. 934 §1. The Most Holy Eucharist:
1/ must be reserved in the cathedral church or its equivalent, in every parish church, and in a church or oratory connected to the house of a religious institute or society of apostolic life;
2/ can be reserved in the chapel of the bishop and, with the permission of the local ordinary, in other churches, oratories, and chapels.
§2. In sacred places where the Most Holy Eucharist is reserved, there must always be someone responsible for it and, insofar as possible, a priest is to celebrate Mass there at least twice a month.
Can. 935 No one is permitted to keep the Eucharist on one’s person or to carry it around, unless pastoral necessity urges it and the prescripts of the diocesan bishop are observed.
Can. 936 In the house of a religious institute or some other pious house, the Most Holy Eucharist is to be reserved only in the church or principal oratory attached to the house. For a just cause, however, the ordinary can also permit it to be reserved in another oratory of the same house.
Can. 937 Unless there is a grave reason to the contrary, the church in which the Most Holy Eucharist is reserved is to be open to the faithful for at least some hours every day so that they can pray before the Most Blessed Sacrament.
Can. 938 §1. The Most Holy Eucharist is to be reserved habitually in only one tabernacle of a church or oratory.
§2. The tabernacle in which the Most Holy Eucharist is reserved is to be situated in some part of the church or oratory which is distinguished, conspicuous, beautifully decorated, and suitable for prayer.
§3. The tabernacle in which the Most Holy Eucharist is reserved habitually is to be immovable, made of solid and opaque material, and locked in such a way that the danger of profanation is avoided as much as possible.
§4. For a grave cause, it is permitted to reserve the Most Holy Eucharist in some other fit-ting and more secure place, especially at night.
§5. The person responsible for the church or oratory is to take care that the key of the tabernacle in which the Most Holy Eucharist is reserved is safeguarded most diligently.
Can. 939 Consecrated hosts in a quantity sufficient for the needs of the faithful are to be kept in a pyx or small vessel; they are to be renewed frequently and the older hosts consumed properly.
Can. 940 A special lamp which indicates and honors the presence of Christ is to shine continuously before a tabernacle in which the Most Holy Eucharist is reserved.
