When Christians do horrible things, it’s easy to let their faith off the hook. We say things like, “They aren’t really Christians,” or “They are only Christians on paper.” This reaction makes sense. No one wants Christ’s name linked to cruelty, violence, or hatred.
But what if that response misses a deeper issue?
Instead of simply saying someone is "not a Christian," ask a tougher question: What beliefs led them to think their actions reflected Jesus? This difference matters because beliefs shape how we live. What you believe about God affects how you treat others, handle disagreements, and use any influence you have.
History gives us endless examples.
In many places all over the world, political leaders have called themselves Christians while leading violence, oppression, and war. Sometimes, church leaders have supported them and said they were doing God’s will. This doesn’t mean Christianity teaches these things, but it shows that people can claim Christ while holding beliefs that lead to harmful results.
Closer to home, you’ve probably seen pastors or Christian influencers in the news for harsh words, conspiracy theories, public stunts, or language that targets whole groups. It’s easy to say, "Well, they’re obviously not Christians."
But that reaction can let harmful teaching go unchecked.
Every Belief Bears Fruit
The truth is, what we believe about God matters. Beliefs about God aren’t just for seminaries or Bible scholars. They show up in daily life. They shape your relationships, your politics, your compassion, your generosity, and how you talk to others made in God’s image.
Jesus pointed this out many times. He taught that a tree is known by its fruit (Matthew 7:16-20). In other words, what you believe will eventually show in your actions.
Paul described the fruit of the Spirit as "love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control" (Galatians 5:22-23). These qualities should become more visible in the life of someone following Christ.
If teaching keeps producing fear instead of peace, contempt instead of kindness, or hostility instead of love, it’s worth asking if something has gone wrong—not just with the person, but with the beliefs behind their actions.
This doesn’t mean every Christian with imperfect beliefs will become abusive or harmful. Everyone has blind spots. Every church tradition makes mistakes. The consequences can extend far beyond theological disagreements.
When Christians are taught that some people are beyond God’s love, that enemies deserve contempt instead of prayer, or that political power matters more than Christlike character, these beliefs don’t stay in Sunday sermons. They shape families, communities, churches, and even whole nations.
That’s why it’s important not to ignore harmful beliefs just because they’re hard to face.
How Jesus Taught Us to Discern Truth
At the same time, pointing out harmful teaching shouldn’t become an excuse to feel self-righteous.
Every Christian should talk about these issues with humility, knowing that anyone can misunderstand Scripture or let culture shape their faith more than Jesus’ example.
The goal isn’t to make a new list of people to judge. But when you see teaching that keeps stirring up hatred, celebrates division, encourages cruelty, or takes away people’s dignity, it’s fair and necessary to ask if it reflects the heart of Jesus.
Likewise, when you see teaching that inspires sacrificial love, forgiveness, mercy, justice, and compassion, you start to see the kind of fruit Jesus talked about. Sermons, podcasts, YouTube videos, and social media clips spread ideas faster than ever before. Every Christian has unprecedented access to teachers from around the world, which creates opportunity and requires discernment.
Not Every "Christian Voice" Speaks for Christ
Not every confident Christian speaker speaks for Christ. Not every popular Christian preacher shows Christ’s character.
Not every message that uses Bible verses faithfully shares the gospel.
Scripture encourages believers to "test the spirits" (1 John 4:1), check what they hear (Acts 17:11), and compare teaching to the life and words of Jesus. Ask whether the teaching consistently reflects the character of Christ.
Does it lead to humility or arrogance? Does it grow compassion or contempt? Does it guide people toward reconciliation or constant conflict? Does it bring people closer to Jesus or just deeper into fear and outrage? Those questions matter because theology is never just theory. It shapes who you become. It influences the churches you build. And it affects the witness Christians show to the world.
When believers excuse harmful teaching by saying, "Those people aren’t really Christians," they might miss a chance to address the beliefs that keep causing harm.
Instead, a better response is to admit that people can truly see themselves as Christians while holding flawed beliefs. Then, with honesty and kindness, point back to Jesus’ teachings and invite others to see if their beliefs are producing the fruit He described.
In the end, Christian theology shouldn’t be judged just by labels. It should be measured by whether it leads people to love God more and love their neighbors better.
If a belief system keeps producing hatred, fear, violence, or dehumanization, it needs to be examined closely. But if it leads to love, peace, mercy, humility, and self-control, it starts to show the heart of the One Christians follow.
