Foot washing, a practice associated with baptism, carries profound significance. In Harper Lee's "To Kill a Mockingbird," this poignant ritual symbolizes humility and service, reflecting biblical teachings on servant leadership and mutual support within the body of Christ. The themes in Mrs. Dubose's character and Atticus Finch's role depict humanity's shared values and commitment to doing what is right over personal gain or popularity, serving as reminders for us to walk in love and understanding and embodying humility and servanthood in our own actions.
