Foot washing

Foot washing is a religious ceremony engaged in by certain sects of Christianity as a sign of personal humility before God and before their fellow Christians. It is derived from the Middle Eastern custom of a house owner or their servant washing a guest's feet upon entering as a symbol of courtesy, and was performed by Jesus upon His disciples during the last supper to show how the disciples are to model His behavior.

In the EMPATH: The Luckiest Smurf story series, Tapper engages in the annual ritual of washing his fellow Smurfs' feet every Easter as a sign of his devotion to God and to his fellow Smurfs.
