There's an interesting detail included by John in his account of the beginning of the Last Supper. Jesus removes his "outer garment". Literally, this would prevent his tunic from being souled as he went about the messy deed of washing the feet of his disciples. But it is a symbol as well: Jesus is peeling away the external, superficial and revealing his interior heart -- what is at his core and center. Everything that happens next during this meal will show us who He is and what is most important to HIm.
