Par 9 and 10
9. How did “foolish and ignorant debates” affect the early Christian congregation?
9 God’s Word gives specific advice concerning the types of unrighteousness that Christians must renounce or reject. For instance, in the immediate context of 2 Timothy 2:19, we find that Paul tells Timothy “not to fight about words” and to “reject empty speeches.”(Read 2 Timothy 2:14, 16, 23.) Some members of the congregation were promoting apostate teachings. Also, it appears that others were introducing controversial ideas. Even if the latter were not directly unscriptural, they were divisive. They resulted in bickering and arguing over words, creating a spiritually unhealthy atmosphere. Hence, Paul stressed the need to “reject foolish and ignorant debates.”
10. How should we respond when confronted with apostasy?
10 Today, Jehovah’s people are not often confronted with apostasy within the congregation. Still, when exposed to unscriptural teachings, regardless of the source, we must decisively reject them. It would be unwise to engage in debates with apostates, whether in person, by responding to their blogs, or by any other form of communication. Even when the intention is to help the individual, such conversation would be contrary to the Scriptural direction we just considered. Rather, as Jehovah’s people, we completely avoid, yes reject, apostasy.

19. How have some today acted with decisiveness to protect themselves from spiritual dangers?
19 Some who had problems with alcohol before becoming Witnesses have made the personal choice to abstain from alcoholic beverages altogether. Others avoid certain types of entertainment that are not in themselves wrong but that can fuel personal moral weaknesses. (Ps. 101:3) For example, before becoming a Witness, one brother enjoyed the immoral atmosphere of the dance parties he frequented. But after learning the truth, he has completely avoided dancing even at Witness gatherings for fear of awakening improper desires or thoughts from his past. Of course, Christians are not required to abstain totally from alcohol, dancing, or other things that are not wrong in themselves. We are all expected, however, to take decisive and thorough action to protect ourselves from spiritual dangers.
