Whenever Christians critique or even rebuke false teachers, there is usually a backlash. There is always an ensemble of a believers ready to jump to their defense. They will argue that these false teachers do say much that is true, so we ought not dismiss them entirely. We shouldn’t throw the baby out with the bath water.
To be perfectly fair, it isn’t entirely inaccurate to acknowledge that many pseudo-Christian religions (Mormonism, Jehovah’s Witnesses, etc), do have elements of truth within them. Even the prosperity preacher who claims, “GOD WANTS TO MAKE YOU RICH!”, probably, at some point, says something that aligns with Scripture. That’s what makes these various pseudo-Christian beliefs so incredibly dangerous. They look so much like Christianity.
Charles Spurgeon once said, “Discernment is not knowing the difference between right and wrong. It is knowing the difference between right and almost right.” That’s exactly what so many of these false religions are: almost right.
If you were to walk into a Satanic Temple (yes, those exist, it’s not just a hyperbolic example) it would be glaringly obvious that they believe a false religion and are worship a false god. But, with prosperity doctrine, Mormonism, Jehovah’s Witnesses, Oneness Pentecostals, etc, it isn’t quite so obvious. Because many of them will acknowledge that authority of Scripture and place a large emphasis on Jesus, it’s all quite convincing.
For those of us who’ve been Christians for a while and have developed discernment, we must speak out against false teaching. Not only because it’s Biblical, but because discipleship is important. We should be helping our brothers and sisters in Christ grow in their walk with God. If they are believing a lie, we need to point them to Scripture so they can see the truth. We should not want them to be deceived or lead astray.
I have no hatred for prosperity preachers, Mormons, JWs, or any false teacher. But if we’re to be honest, they are lost, just like any atheist, Muslim, Buddhist, or Satanist. What I want for them is to repent and start preaching the true Gospel. Can you imagine how many people could hear the Gospel is Joel Osteen started preaching it?
In conclusion, essentially yes, we need to throw the baby out with the bath water. While there may be elements of truth coming out of the mouths of false teachers, they are still wolves in sheep’s clothing. Regardless of their intent, they are deceiving people with a false gospel. If we do endorse these individuals, ultimately, we endorse the heresy they preach as well.
