Why do Pharisees and scribes oppose Jesus receiving sinners?

The opposition from the Pharisees and scribes towards Jesus receiving sinners illustrates their self-righteous attitude and misunderstanding of God’s grace. They considered themselves worthy of God's favor due to their strict adherence to the law, and therefore, they rejected those deemed unworthy. In their eyes, Jesus’ association with sinners undermined their moralistic standards and legalistic beliefs. By showing kindness and compassion toward those society deemed unworthy, Jesus revolutionized the understanding of God's grace, emphasizing that it is not based on merit but solely on His mercy. This radical notion challenged the norms of religious elitism and highlighted the inclusiveness of God's kingdom.
