This is what I found in the transcript related to the date August 14 2015 (Royal Comision of Australia):
18 Q. And if they don't actively disassociate, then they
19 will be disfellowshipped as apostate?
20 A. No, an apostate is someone who actively goes against
21 what the Bible teaches.
This is a half true. Of course, the Bible does not teach that we must obey what seven men in NY publish in The Watchtower. Nevertheless, the GB says:
“Persons who deliberately spread (stubbornly hold to and speak about) teachings contrary to Bible truth as taught by Jehovah's Witnesses are apostates.” Pay Attention to Yourselves and to All the Flock p.94
