Greg Koukl made a great point on a Stand to Reason Podcast about how pastors must pass this as one of their tests: Titus 1:9 He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it.
All “Christian” Left pastors fail that test, because they don’t hold firm to the word and don’t consider it trustworthy. So of course they can’t give instruction in sound doctrine or rebuke those who contradict it. They are the ones who need rebuking for teaching false doctrines!
But many pastors with sound doctrine fail to rebuke false teachers. They tell themselves they are being nice, but they are just being nice to themselves and the wolves and are being mean to their sheep.
