Welcome to Day 2796 of Wisdom-Trek, and thank you for joining me. This is Guthrie Chamberlain, Your Guide to Wisdom – Theology Thursday – Top 10 Logical Fallacies That Lead to Bad Theology and Misguided Evangelism. Wisdom-Trek Podcast Script - Day 2796 Welcome to Wisdom-Trek with Gramps! I am Guthrie Chamberlain, and we are on Day 2796 of our Trek. The Purpose of Wisdom-Trek is to create a legacy of wisdom, to seek out discernment and insights, and to boldly grow where few have chosen to grow before. Our current series of Theology Thursday lessons is written by theologian and teacher John Daniels. I have found that his lessons are short, easy to understand, doctrinally sound, and applicable to all who desire to learn more of God’s Word. John’s lessons can be found on his website theologyinfive.com. Today’s lesson is titled Top 10 Logical Fallacies That Lead to Bad Theology and Misguided Evangelism. Theology and evangelism must be grounded in truth. Scripture calls us to worship God with all our heart, soul, and mind. When Christians lean on faulty reasoning, they twist the Word of God and open the door to error. Logical fallacies are not harmless; they often lead to heresy, false conversions, and a compromised witness. The gospel is too precious to be diluted by sloppy thinking. Here are ten common logical fallacies that regularly poison Christian teaching and outreach, along with why they are so dangerous.

1. Appeal to Emotion

God created us with emotions, and they can be powerful tools in responding to His truth. But when emotions become the foundation of a theological claim or evangelistic appeal, the message becomes distorted. Frightening people with hellfire or guilt-tripping them into “saying a prayer” is not preaching the gospel. It is manipulating feelings. This may produce outward responses, but it rarely produces genuine repentance. The Holy Spirit uses the truth of the gospel to convict and transform, not emotional spectacle.

2. Straw Man

We are called to represent the truth faithfully, and that includes how we handle opposing views. Creating a caricature of someone else’s beliefs just to knock it down is not discernment; it is dishonesty. Saying, “Calvinists believe God delights in sending people to hell,” or “Arminians think they save themselves,” misrepresents those views and violates the command to bear true witness. If we cannot refute what someone actually believes, we have no business opposing it at all.

3. Slippery Slope

There is a difference between wise caution and irrational fear. When someone says, “If we allow this doctrinal disagreement, we’ll abandon the gospel next,” or “If women teach children, we’ll soon have drag queens in the pulpit,” they are not contending for the faith. They are avoiding honest discussion. Scripture warns against compromise, but it also warns against making false accusations. We must examine each issue on its own merit, not use fear tactics to shut down thought.

4. Circular Reasoning

The Bible is self-authenticating, but it should not be defended with circular logic. Saying, “The Bible is true because it says it is,” may sound spiritual, but it avoids meaningful engagement with the reliability of God’s Word. Scripture invites examination. God has confirmed His Word through history,...
