Luke 12:42
Luke 12:4242And the Lord answered, “Who then is the faithful and wise manager, whom the master puts in charge of his servants to give them their portion at the proper time?
is one of the cornerstone verses for the Watchtower's "faithful and discreet slave" doctrine — the parallel to . Since October 2012, the slave has been identified exclusively with the Governing Body acting collectively when providing spiritual instruction. The "domestics" are the rest of the Witnesses. The slave was supposedly appointed by Jesus in 1919. Before October 2012 the Watchtower taught that the slave was the entire anointed class — a position the March 1, 1981 Watchtower called the only-the-leading-ones-as-slave reading apostate, before the Governing Body adopted that exact reading in 2012.
The parable in belongs to a series of four readiness parables (the faithful servant, the ten virgins, the talents, the sheep and goats). Jesus is teaching individual faithfulness and watchfulness — not establishing an institutional office to be filled by eleven men in New York nineteen centuries later. Pair with the 1981 Watchtower (March 1, pp. 24-26) condemning the only-leaders-as- slave reading as apostate, and the July 15, 2013 Watchtower formalising that exact position. The same teaching cannot be apostasy in 1981 and divine truth in 2012 unless one of the publications was wrong. Either way, the organisation's authority claim is undermined by its own publications.
The NWT renders ho phronimos as "the discreet one" and pistos oikonomos as "the faithful steward" — yielding "the faithful steward, the discreet one." Standard English translations render "the faithful and wise/prudent manager" or "the faithful and sensible steward." The choice of "discreet" for phronimos is a long-standing NWT preference and is the load-bearing English phraseology behind the JW phrase "the faithful and discreet slave" — a self-description that has functioned as a corporate identity marker since the 1920s. The English rendering itself is doctrinally tendentious in a way that "wise" or "prudent" would not be: "discreet" carries connotations of cautious, quiet authority that fit the Governing Body's preferred self-image.
