Then for consitencies sake why didn't you do them all? I assume you didn't do any holy kissing because you separated the men from the women, if not, why using your logic? A holy kiss would have been between same sex and opposite sex but you separate sexes, why? Why did the sexes separate when a woman washed Christ's feet and there are other instances of foot washing of mixed sexes and nothing taught about it, fair question? Now I would have a big problem with another man washing my wife's feet or kissing her, granted?
Where did Christ command a holy kiss?
Decorum for one thing, but also the disciples were all male, thus males washed male feet. Females washed females feet.
