Each must make its needs known to the other. Communication is essential in a family, and among families, and in workplaces, and in communities, and in every setting in which people gather. George Boardman, in his 1899 comments on the ninth commandment suggested that Language is not only wonderful, language is sacred. It is by means of words that people can understand and enjoy one another, and can cooperate in carrying on and building up society. Language is the bridge between person and person.
Language is the covenant of the people, the sacramental bond of the people speaking it . . .
Hence language, in order to be true to its great mission, must itself be true - that is, trustworthy. For confidence in one another is the basal stone of society. If we need to communicate with one another, and we do, we need to be able to trust the messages we receive. We need to know that what someone tells us is congruent with what they believe to be true. There can be no working relationship without trust, and there can be no trust if we find that what the other tells us does not check out in experience.
