Diocese of Westminster Ordo 2026 D2 Mass on the occasion of news of a death, final burial, or the first anniversary (GIRM, no. 381). D3 Daily Mass for the dead (GIRM, no. 381). When D1 and D2 are not permitted, neither is D3. CHOICE OF EUCHARISTIC PRAYER Eucharistic Prayer I (the Roman Canon) may always be used, and particularly on days for which proper texts or insertions are provided, the feasts of apostles and saints mentioned in the Prayer, and on Sundays. Eucharistic Prayer II is more appropriately used on weekdays and in special circumstances. It has its own Preface but this may be replaced by another. It is also suitable for a Mass for the Dead as it has a proper insertion.
Eucharistic Prayer III is preferred for Sundays and feasts of saints who may be named within it. It is also suitable for a Mass for the Dead as it has a proper insertion. Eucharistic Prayer IV is an integral text with an invariable Preface. It may be used on Sundays and ferial days of Ordinary Time, when a Mass has no Proper Preface of its own. Eucharistic Prayers I and II for Reconciliation have their own Prefaces but may be used with other appropriate Prefaces that refer to penance, for example, the Prefaces of Lent. Eucharistic Prayers I-IV for use in Masses for Various Needs and Occasions may be used in association with the Votive and other Masses noted in the rubrics for each Prayer.
The Prefaces form an integral part of each Prayer and therefore may not be replaced. FULFILMENT OF OBLIGATION The obligation of participating in the Mass is satisfied by assisting at Mass wherever it is celebrated in a Catholic rite, either on the Sunday or Holy Day itself or on the evening of the previous day (Canon 1248:1). EUCHARISTIC FAST Whoever is to receive the blessed Eucharist is to abstain for at least one hour before Holy Communion from all food and drink, with the sole exception of water and medicine (Canon 919:1).
A priest who, on the same day, celebrates Mass twice or three times may consume something before the second or third celebration, even though there is not an hour’s interval (Canon 919:2). The elderly, and those who are suffering from some illness, as well as those who care for them, may receive the blessed Eucharist even if within the preceding hour they have consumed something (Canon 919:3). RECEPTION OF THE EUCHARIST A SECOND TIME ON THE SAME DAY It is permitted to receive Holy Communion twice in one day, provided this takes place during the celebration of Mass (Canon 917). This provision is to be observed except in the case of Viaticum for the dying. 10
