After the Quicunque vult, so you will discover, your Prayer Book has the Litany. But when, be you Protestant or Papist, did you last hear that said or sung in church or in procession? Yet Cranmer ordered it to be 'sung or said' three times a week.
Cranmer's Litany affords, as Cuming pointed out in his history of Anglican Liturgy, a superb example of Cranmer's mind at work, a mind which was a capacious repository of everything Cranmer had ever prayed, or heard, or read. Essentially his Litany is derived from the Sarum Litany but phrases and expressions and ideas break in from an extremely wide spread of sources within the Tradition of Western Latin Christendom. Except that it omits the Saints - a fault easily remedied - it is a scintillating summation and efflorescence of that Tradition. Yet we Anglicans so often fail to realise we're sitting on something good.
Its predecessor Litanies were used in ordinations, in Rogation processions for the crops, when processing the relics round the town ... The great Forty Hours Devotion - the Sacrament exposed for three days as a stimulus for prayer in times of great adversity - has the Litany at its heart. We used the Litany once a year before the whole College at Lancing, and I was always moved by the humbled silence of the student body ... not all of whom were always exempt from the temptations of adolescent self-consciousness ... as priest and choir moved round that great Minster Church of the Assumption and S Nicolas singing Cranmer's Litany to the old Sarum tones.
Once a year is not enough. Or, to be practical, Fathers, chopped-up bits of it go very well into Benediction.
