While doing research for an upcoming article on Admiral Sir Max Horton, I stumbled across a great website on the Headquarters for the Western Approaches which included The Naval Prayer. It provides insight into the mindset of mariners in the British Empire and the Royal Navy.
O eternal Lord God, who alone spreadest out the heavens and rulest the raging of the seas; who hast compassed the waters with bounds until day and night come to an end; be pleased to receive into thy Almighty and most gracious protection the persons of us thy servants and the Fleet in which we serve. Preserve us from the dangers of the sea and from the violence of the enemy; that we may be a safeguard unto our most gracious Sovereign, King George and his dominions, and a security for such who pass on the seas upon their lawful occasions; that the inhabitants of our Island and Empire may in peace and quietness serve thee our God; and that we may return in safety to enjoy the blessings of the land with the fruits of our labours, and with thankful remembrance of thy mercies to praise and Glorify thy holy Name; through Jesus Christ our Lord. Amen
