The answer is: Twice a week

Luke 18:9-14

In the intriguing parable of the Pharisee and the tax collector found in Luke 18:9-14, we are introduced to two very different figures. The Pharisee, proud and self-assured, boasts about fasting twice a week, a practice he adheres to meticulously. In contrast, the humble tax collector simply beats his chest in repentance, asking for mercy.

Fasting in the Jewish tradition was a way to seek closeness to God, and while it wasn’t required to happen twice a week, this Pharisee took it upon himself to go above and beyond the norms—essentially checking off religious obligation boxes while missing the depth of true spirituality. Fun fact: the Pharisees believed in strict adherence to the law and often interpreted it in ways that made them seem morally superior, while their hearts sometimes strayed from the spirit of the law.

This parable holds echoes from other Biblical narratives where outward appearances don’t match inward sincerity. Think of King David, who displayed his heart for God despite his failings, contrasting sharply with the arrogance of the Pharisee.

Luke's Gospel often highlights themes of humility and grace, capturing the essence of God's mercy and the idea that self-righteousness can blind us. Just as this story shows, sometimes, it’s the heart posture behind our actions that matters the most. That humble send-off of the tax collector provides a profound lesson in knowing where true worth lies—not in religious acts, but in openness to grace.
