Not much has changed since the days of the early Apostles. Paul dealt with it in his day and now we too do well to put up with it.
But I fear, lest somehow, as the serpent deceived Eve by his craftiness, so your minds may be corrupted from the simplicity that is in Christ. For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted—you may well put up with it! 2 Corinthians 11:3,4
Just because someone uses the name of Jesus does not necessarily mean they are representing the true Son of the living God. By what spirit are these teachers being motivated to rule over God’s Church?
I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel, which is not another; but there are some who trouble you and want to pervert the gospel of Christ. But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed. For do I now persuade men, or God? Or do I seek to please men? For if I still pleased men, I would not be a bondservant of Christ. Galatians 1:6-10
Therefore, if I come, I will call to mind his deeds which he does, prating against us with malicious words. And not content with that, he himself does not receive the brethren, and forbids those who wish to, putting them out of the church. Beloved, do not imitate what is evil, but what is good. He who does good is of God, but he who does evil has not seen God. 3 John 10,11
Have you been put out of the local Church? People who believe God still speaks are welcome here.
