Foot washing in Baptism is a tradition among some Baptist communities, where individuals wash each other's feet as a symbol of humility, service, and love for others before participating in baptism. This custom is rooted in Jesus' commandment to wash the disciples' feet during his last supper. The practice involves praying over the individual or reciting a short liturgy, and serves not only to sanctify the baptismal process but also to reinforce its deep significance.
