Chapter and Verse

There was a well-founded tradition in the Royal Navy and in the Royal Canadian Navy of using Biblical quotations as shorthand for sending messages.

Many pithy, witty or just plain snippy words to the wise were relayed via Biblical quotes, which had the virtue of being concise, to the point, and suitable for a range of occasions and eventualities.

References to quotations (i.e. 1 Corinthians 15-33)1 were used singly or as part of a longer message. Brevity was especially important during wartime. Most signals sent at sea during World War II were conveyed using light or by radio. The sender had to keep messages short, for the sake of efficiency and security.

Even those unfamiliar with scripture were able to use this technique, thanks to a portable digest of Biblical chapter and verse known as a "vade mecum".

Latin for ‘go with me’, vade mecum refers to a handbook that is carried on the person and consulted as required. Equipped with a copy of this handbook, even people who were not scholars of the Bible could borrow its verses to make a point or deliver a rebuke.

In any case, some knowledge of the Bible was almost a given during the period when such handbooks were in use. Many schoolchildren received a good grounding in scriptural chapter and verse, whether they received this education at school, Sunday school, home, or all three.

Thus the ship's Captain, signalmen, or personnel working on the bridge took advantage of Biblical writings to make a few short words go a very long way.

It became almost a craze among senior escort officers in Britain's Royal Navy to embed Biblical references in their signals. Examples of such exchanges include the following:

Situations when Bible quotes were used were many and varied. These occasions might include:

The content of such Biblically-based messages was often light-hearted, but it could also be serious:

Whether the intention was to praise, rebuke, or simply to entertain and enlighten, the practice of using Biblical quotations for messaging and signalling was a clever way of getting complex ideas across in a succinct fashion.
