It is quite a different matter with a former Christian who is "disassociated." This designation is applied basically in two situations: First, though it is uncommon, a person might decide that he absolutely no longer wants to be a Witness. We do not mean a person such as is described above, a spiritually weak or discouraged Christian who may express some doubts. Rather, we mean someone who resolutely declares that he absolutely is no longer one of Jehovah’s Witnesses. Since in the past he voluntarily became a baptized member of the congregation, it would now be proper for him to inform the congregation that he is ending this relationship. It would be best if he did this in a brief letter to the elders, but even if he unequivocally states orally that he is renouncing his standing as a Witness, the elders can deal with the matter.—1 John 2:19.
The second situation involves a person who renounces his standing in the congregation by joining a secular organization whose purpose is contrary to counsel such as that found at Isaiah 2:4, where we read concerning God’s servants: "They will have to beat their swords into plowshares and their spears into pruning shears. Nation will not lift up sword against nation, neither will they learn war anymore." Also, as stated at John 17:16, "they are no part of the world, just as I [Jesus] am no part of the world."—Compare Revelation 19:17-21.
In either of these two situations, the person by word and/or actions has clearly terminated his status as one of Jehovah’s Witnesses, disassociating himself. Hence, the elders will announce briefly to the congregation that this individual has disassociated himself. Those in the congregation will accept the person’s decision and thereafter will view him as a former brother with whom they would not fellowship, in harmony with what we read at 1 Corinthians 5:11 and 2 John 9-11.
As can be appreciated, the spiritually weak and inactive son about whom the question was asked has not become a "disassociated" person in either of these two senses and no such announcement has been made in the congregation. So it still may be possible to aid him in the spirit of Romans 15:1: "We, though, who are strong ought to bear the weaknesses of those not strong."—See also Isaiah 35:3.
So, when can we expect an announcement that the WTS, based on its 10-year NGO affiliation with the UN-DPI, has disassociated itself from True Worship™?
