What does the Bible say about useless religious practices?

In Titus 3:9-11, the apostle Paul instructs believers to avoid foolish questions, genealogies, and debates about the law because such disputes are unprofitable and vain. These 'foolish questions' refer to those not revealed by God, leading to discussions and arguments that distract from the centrality of Christ. The underlying message is that if our religious practices—whether they be rituals, traditions, or debates—do not point to or involve Christ, they become meaningless and lead us away from the truth. In essence, focusing on Christ is essential for a fruitful and genuine faith.
