What does the Bible say about the Pharisees' traditions?

Throughout the Scriptures, particularly in the Gospels, Jesus addresses the issue of the Pharisees' traditions, pointing out that they often prioritize ritual observance over genuine faith and love for God. In Luke 11, for example, Jesus condemns the Pharisees for their external focus on ritual cleanliness, while their hearts are full of wickedness. This hypocrisy illustrates a broader danger in religion: substituting sincere faith with mere rituals. The traditions they held dear often contradicted God's true commandments, highlighting the importance of understanding and obeying Scripture in spirit and truth rather than merely following man-made rules.
