At the Last Supper, Jesus provided a clear example of how the church should serve others. Instead of emphasizing structure and hierarchy, he demonstrated humility and selfless service by washing his disciples' feet. This act highlighted that true leadership in the church is about serving and caring for others, not about authority or organization.

While his disciples suggested creating more formal systems like selecting officers and establishing standards, Jesus focused on personal humility. His actions showed that the core purpose of the church is to serve with love and humility, setting a model for how believers should lead and act in their community.
