Calling Out False Teachers By Name
"Several clips of Voddie Baucham (and some commentary) explaining why it is biblical, right, and necessary to call out false teachers (this video itself does not call out false teachers). Most of the clips in this video are from an introductory message for a conference where Justin Peters subsequently critiqued specific false teachers." from video introduction.
"For most of church history, it took extraordinary energy and effort to influence the masses. Messages had to be copied by hand, and teachers had to travel by foot or horseback. There were no cars or airplanes, and no printing presses, websites, or Facebook pages. But today just about every false teacher has a Twitter account....We begin by acknowledging not just the possibility of false teaching, but the certainty of it. We should not be surprised to find false teaching in the church today. Jesus and his apostles are very clear that false teachers will arise....What we might find surprising — both from Jesus and his apostles — is how revealing the everyday lives of false teachers are about their falseness. They are not just false in their teaching, but also in their living...Jesus is not only the greatest and truest teacher who ever lived, but he also is the great rescuer, who has redeemed us from sin and will keep those who are truly his from soul-destroying error. No matter how small a minority the church becomes, and no matter how fragile we feel, the very one who is both the subject of true teaching and the model of true living is also our life-and-soul-preserver.
As God preserved Noah (2 Peter 2:5) and rescued Lot (2 Peter 2:7), so the Lord Jesus will rescue his true people from the false teaching — and false living — of false teachers." from the article: The Surprising Truth About False Teachers (link)
“False christs and false prophets will arise and perform signs and wonders, to lead astray, if possible, the elect. But be on guard; I have told you all things beforehand.” Mark 13:22–23
