Vanderhoven, perhaps I was being pedantic but I was trying to answer your question. It is not a relationship with the "Governing Body" that is required, but to support the Christian congregation (Christ's anointed "brothers"). It may be argued that you cannot support the Christian congregation without supporting the "Governing Body", and that may be true although I do not hold to that view. But I don't read anywhere in the publications that we need to have a relationship with the "Governing Body", only with the Christian congregation (Christ's anointed "brothers").
But since this teaching is analogous to the requirement of baptism (the antitypical ark), perhaps it is worth addressing the question about what happens to those who do not have a Christian baptism.
Vanderhoven7 : Where does the GB stipulate that ex-Jehovah Witnesses who
are honest-hearted apostates to Jehovah's organization may survive
Armageddon?
No doubt the GB considers "honest-hearted apostate" to be an oxymoron, so the literature only goes so far as to say God has committed judgment into
Jesus’ hands, not ours. But perhaps I should mention I had my tongue firmly in cheek when I excepted the members of JWD from a free pass.
peacefulpete : I noticed on the WT website they revised the 1978 brochure in 1979.
Yes. They read slightly differently :
1978
No.
Many millions that have lived in centuries past, who were not
Jehovah’s Witnesses, will come back in a resurrection and have an
opportunity for life. Many now living may yet take a stand for truth and
righteousness before the “great tribulation,” and they will gain
salvation. Moreover, Jesus admonished that we should not be judging one
another. We tend to look on the outward appearance; God looks on the heart. He
is the one who sees accurately and judges mercifully. He has committed judgment into
the hands of Christ Jesus, not ours.—Matthew 7:1-5.
1979

You can find it online at the link I provided - JW in the 20th century, 1979, p.29. I don't think the 1978 version is online.
