O God of ineffable mercy, who didst give grace and fortitude to blessed Edmund the king to triumph over the enemy of his people by nobly dying for thy Name: Bestow on us thy servants, we beseech thee, the shield of faith, wherewith we may withstand the assaults of our ancient enemy; through Jesus Christ our Redeemer, who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever.
