Until the official period of mourning is over after the state funeral, there are some temporary changes to Ordinariate liturgy:
If a Mass intention is free, the Mass should be offered for the repose of the Queen's soul.
She should be remembered in all public devotions - The Litany(p. 1061) during a public holy hour in place of other devotions.
Masses on days that are memorials or optional memorials will be the Requiem Mass found on page 1024. She is named in the propers as: "... thy handmaid Elizabeth".
The Dies irae is always recited at a requiem per our customs.
The readings are the regular readings of the day.
Our Lady of Sorrows is an exception to the displacement; it is still observed.
After all Masses, including the Sunday Mass, up to and including the day of her state funeral, the attached versicles and responses with collect from the breviary will be said or sung instead of any other prayers after the last Gospel and before the final hymn.
V/. O Lord, show thy mercy upon us.
R/. And grant us thy salvation.
V/. O Lord save the King.
R/. And make thy chosen people joyful.
V/. Endue thy ministers with righteousness.
R/. And bless thine inheritance.
V/. Give peace in our time, O Lord.
R/. Because there is none other that fighteth for us.
V/. O God, make clean our hearts within us.
R/. And take not thy Holy Spirit from us.
Let us pray. Almighty God, the fountain of all goodness, we humbly beseech thee to bless our Sovereign Lord King Charles, the parliaments in all his dominions, and all who are set in authority under him; that they may order all things in wisdom, righteousness, and peace, to the honour of thy holy name, and the good of thy Church and people; through Christ our Lord. R/. Amen
