New Testament Greek is by Balinese standards an extremely impolite language. Consider, for example, the second person pronoun. When speaking to God, to a nobleman, to a friend, to a pupil, or to a slave, the same word is used. In Balinese this is completely different. In the above examples one would differentiate various social ranks and use terms which, more or less freely translated, mean “adored one” or “he who is borne on the head”, “feet of Your Highness”, “older (or younger) brother”, “little one”, and “you”. (…) In Balinese one has to cope with three vocabularies within the language, each of which, at a moderate estimate, includes some hundreds of words. One employs the ordinary common language (“Low Balinese”) when speaking with intimates, equals, or inferiors; polite terms must, however, be used as soon as one begins to speak to one’s superiors or to strangers; and “deferential” terms are obligatory in all cases when one is so bold as to speak of parts of the body, or the acts, possessions, and qualities of important people. The Balinese sums up the two last named vocabularies under the term alus (“fine”, or “noble”): we say “High Balinese”. (…)
In the parable of the Prodigal Son, the younger son, who feels himself less than a slave, speaks to his father in High Balinese; the elder son may use the intimate Low Balinese. When, however, the latter severs himself from the intimate family community, he uses High Balinese to express his contempt, thus placing a gulf between himself and his father.
