The following quote is taken from the September 15, 2002 edition of The Watchtower, p.16-18:
"In the first century, such individuals as Hymanaeus, Alexander, and Philetus, were advocating ideas that did not fit "the pattern of healthful words." (1 Timothy 1:18-20; 2 Timothy 2:16,17) How could the early Christians avoid being led astray by apostates? By carefully studying the inspired writings and applying them in life. Those walking in accord with the example they had in Paul and other faithful ones were able to recognize and reject anything that did not conform to the pattern of truth they had been taught. (Philippians 3:17; Hebrews 5:14) Instead of being "mentally diseased over questionings and debates about words," they continued moving ahead in their positive course of godly devotion. (1 Timothy 6:3-6) We do the same thing when we keep on putting into practice the truths we have learned..................."
"Satan tries to break our integrity through the sowing of doubts about what we have been taught. Today, as in the first century,apostates and others seek to destroy the faith of guileless ones. (Galatians 2:4; 5:7, 8) Sometimes they have used the media to spread distorted information or even outright lies about the methods and motives of Jehovah's Witnesses................"
"...............Whatever stumbling blocks were involved, some evidently preferred falsehoods over the truths of God's Word. Soon they stopped practicing the things they had learned, and this was to their own spiritual detriment. - 2 Peter 3:15, 16"
"We cn avoid turning aside to false stories today if we scutinize and are selective about what we listen to and what we read........"And modern-day apostates keep on trying to sow seeds of doubt in order to subvert the faith of Christians..........So we need to be careful."
"..............If our ears are inclined towards disgruntled ones, we need to analyze ourselves prayerfully. (Psalm 139:23, 24) Are we inclined to find fault with Jehovah's people? If so, why?........"
"Rather than being critical, let us maintain a spiritually healthy view of the information received through personal study and congregation meetings. (1 Corinthians 2:14, 15) And instead of questioning God's Word, how much wiser it is to have the attitude of the first-century Beroeans who examined the Scriptures closely! (Acts 17:10,11) Then, let us act on what we learn, turning down false stories and clinging to the truth."
