It is very important, though, not to confuse gossip with legitimate endeavors. It is not wrong to share truthful things with those who have a right or responsibility to hear to such information.
For example, it was not gossip for the household of Chloe to tell Paul about the problems in the church at Corinth.
Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment. For it hath been declared unto me of you, my brethren, by them which are of the house of Chloe, that there are contentions among you. 1 Corinthians 1:10-11
As the founder of that church, Paul had a right to know about those problems. It is not talebearing to talk to a pastor about matters in others lives that they should know about. It is not talebearing to talk to a father or mother about matters affecting their children. It is not wrong for a Christian to warn another person about a serious problem in a church or organization, so long as the information is true and the motive is not to hurt but to help and warn. Before any discussion is initiated however it is prudent to discern whether the scripture below has been prayerfully considered.
Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. Philippians 2:3
And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye? Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye. Matthew 7:3-5
Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing. And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing. Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up, doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil; rejoiceth not in iniquity, but rejoiceth in the truth; beareth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away. When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. And now abideth faith, hope, charity, these three; but the greatest of these is charity. 1 Corinthians 13
Speaking the truth in love is not gossip, but speaking is not always necessary. When in doubt.just be quiet.
