Almighty God, who hast created man in thine own image; Grant us grace fearlessly to contend against evil, and to make no peace with oppression; and, that we may reverently use our freedom, help us to employ it in the maintenance of justice among men and nations, to the glory of thy holy Name; through Jesus Christ our Lord. Amen.
1928 Book of Common Prayer, p. 44
