What does the Bible say about Phariseeism?

Phariseeism, as portrayed in the Bible, represents a type of religion that focuses on external rituals and adherence to human traditions rather than a genuine relationship with God. Jesus warns against the leaven of the Pharisees, which signifies the corrupt teachings and practices that can easily infiltrate the hearts of religious people. These accounts serve to alert us that many among us might harbor a Pharisaical spirit, thinking that our works or traditions earn us favor with God. Instead, true worship requires a heart that is born again by the Spirit, recognizing that all of us are sinners in need of God's grace and mercy. Such an understanding leads us away from a superficial religious practice to a transformative faith that rests solely in Christ.
