@roze4jesus I think it is our responsibility to warn those under our care of false teaching and to lead them in the truth. In Scripture, we see many warnings about being led away from the truth. I think some of Paul’s denouncements of false teachers are similar to David’s imprecatory Psalms - he is furious that there are people leading others towards destruction. I think it should upset us too.
That said, I think how we approach this issue is important. Jesus tells us to love our enemies and to pray for those who persecute us. When we denounce false teaching I think it is appropriate to pray for false teachers and to emphasize that we are speaking not out of hatred for the individual spreading the false teaching, but out of sincere love for those in our care.
If there is a group of people in the Church who are being led astray by these teachings, maybe you could have a Q&A time or a special Bible study / sermon series helping people to understand how to discern truth from error. Maybe a series on ‘What is the Gospel really?’ where you spend a few sessions discussing distortions of the Gospel.
I think doing a deep dive on the Gospel - books like ‘The Prodigal God’ by Tim Keller or ‘The Explicit Gospel’ by Matt Chandler - is a great place to start to lay a foundation for a series on how to avoid false Gospels.
I think you want to be patient / gentle with people who maybe are slow to understand and avoid denouncing a false teacher they follow without tilling the soil of their heart properly first. You want them to come to the conclusion this person’s teaching is false with you so that they truly change rather than just hiding the fact they like that teacher in the future because they know it’s not considered acceptable. We desire heart change and not only social conformity. Though I think the culture we are in may determine our approach to addressing false teaching to an extent. The Lord Jesus grant you wisdom as you serve His Body
Matthew 24:4-8 - Jesus answered: “Watch out that no one deceives you. 5 For many will come in my name, claiming, ‘I am the Messiah,’ and will deceive many. 6 You will hear of wars and rumors of wars, but see to it that you are not alarmed. Such things must happen, but the end is still to come. 7 Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. 8 All these are the beginning of birth pains.
Hebrews 3:12-15 - See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. 13 But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. 14 We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.
Galatians 1:6-8 - I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel— 7 which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. 8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God’s curse!
