We have learned that the church of every age is plagued by false teachers and their deadly doctrine. We have met seven of those false teachers and seen the devastation they bring. We have identified five tests we can apply to any doctrine to determine whether it is false or true. But this leaves us with some important questions: How does a church come to reject sound doctrine? How do we guard ourselves against false teachers and their deadly doctrines? How do we protect ourselves, our families, and our churches from their seductive lies? Thankfully, God has given us clear guidance in his Word, showing us how churches descend into deadly doctrine and how we may protect ourselves against it.
The Pattern of Deadly Doctrine
Most biblical scholars agree that 2 Timothy is Paul’s final letter. He has nearly come to the end of his life, so he picks up his pen to write once more to his young friend. In his last words to Timothy, Paul makes sure to warn him about the danger of false teachers. “For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths” (2 Timothy 4:3-4). In these verses he gazes into the future and describes a church being undermined and destroyed. This is not a prophecy of the death of a single congregation, but a general description of the death of a thousand. He outlines four steps that can progressively lead any congregation from health to death.
