WT 81 9/15 pg 24-26:
NOT SHARING IN WICKED WORKS
25
All faithful Christians need to take to heart the serious truth that God inspired John to write: “He that says a greeting to [an expelled sinner who is promoting an erroneous teaching or carrying on ungodly conduct] is a sharer in his wicked works.”—2 John 11.
26
Many of Christendom’s commentators take exception to 2 John 11. They claim that it is ‘unchristian counsel, contrary to the spirit of our Lord,’ or that it encourages intolerance. Yet such sentiments emanate from religious organizations that do not apply God’s command to “remove the wicked man from among yourselves,” that seldom if ever expel even notorious wrongdoers from their churches. (1 Cor. 5:13) Their “tolerance” is unscriptural, unchristian.—Matt. 7:21-23; 25:24-30; John 8:44. 27
But it is not wrong to be loyal to the righteous and just God of the Bible. He tells us that he will accept ‘in his holy mountain’ only those who walk faultlessly, practice righteousness and speak truth. (Ps. 15:1-5) If, though, a Christian were to throw in his lot with a wrongdoer who has been rejected by God and disfellowshiped, or has disassociated himself, that would be as much as saying ‘I do not want a place in God’s holy mountain either.’ If the elders saw him heading in that direction by regularly keeping company with a disfellowshiped person, they would lovingly and patiently try to help him to regain God’s view. (Matt. 18:18; Gal. 6:1) They would admonish him and, if necessary, ‘reprove him with severity.’ They want to help him remain ‘in God’s holy mountain.’
But if he will not cease to fellowship with the expelled person, he thus has made himself ‘a sharer (supporting or participating) in the wicked works’ and must be removed from the congregation, expelled.—Titus 1:13; Jude 22, 23; compare Numbers 6:26.
