The collect below was for many an essential element of the Eucharist in The Book of Common Prayer 1928 (USA).
It may seem a very small point, but I think the loss of this collect coupled with the lost language of offering up to God "our souls and bodies" one of the great mistakes in the Episcopalian and Anglican liturgical twiggling that accompanied genuine liturgical renewal in the 20th century.
Immediately prior to the following collect the Choir and People would have sung Kyrie Eleison (usually in English as "Lord, have mercy upon us." etc.)
O ALMIGHTY Lord, and everlasting God, vouchsafe, we beseech thee, to direct, sanctify, and govern, both our hearts and bodies, in the ways of thy laws, and in the works of thy commandments; that, through thy most mighty protection, both here and ever, we may be preserved in body and soul; through our Lord and Saviour Jesus Christ. Amen.
O Lord, save the World.
