Lavabo anyone?
“Though some explain it away as a utilitarian action to cleanse the hands before touching ‘thy creatures of bread and wine,’ which will in turn be consumed by priest and people, the weight of church tradition says that this is a moment of spiritual cleansing as the priest assumes the weighty responsibility of bearing the assembly’s prayers and oblations. In other words, the Lavabo isn’t about germiness.” Those are the words of Anglicans Online. But that was before Purell.
