Church House has published online a set of Liturgical Resources for the Celebration of HM The Queen’s Ninetieth Birthday containing: Notes of Guidance; an outline service; collects and graces; and suggested readings.
The resources are available as a PDF here
The notes say:
It is hoped that many churches and communities will be able to celebrate the ninetieth birthday of Her Majesty the Queen. This leaflet contains, by kind permission of the Dean and Chapter, the Outline of the Service of Celebration and Thanksgiving which will be held at St Paul’s Cathedral on Friday 10 June 2016. Churches are invited to use elements of this outline in their own preparations, especially the bidding prayer, intercessions, and act of thanksgiving in the appendices. In addition to the resources below, St Paul’s has commissioned the Master of the Queen’s Music, Judith Weir, to compose a choral anthem, I love all beauteous things, which can be used in the context of a celebration service and is now available.
Also included here are the Collects which The Queen has been pleased to approve for use in services celebrating her birthday, and Graces for use at church and community gatherings. Finally, the Liturgical Commission suggests a number of appropriate readings suited to a celebratory service.
