O Lord, who hast called us to fight under the banner of thy cross against the evil of the world, the flesh and the devil: Grant us thy grace, that clothed in purity and equipped with thy heavenly armour, we may follow thee as thou goest forth conquering and to conquer, and steadfast to the last we may share in thy final triumph; who livest and reignest with the Father and the Holy Ghost, one God, world without end.
