Lucky old me (Don't worry, I am not being smug, I am being sarcastic). This evening I am going to have my feet washed, and I can't say I'm looking forward to it. It may well be accepted by all religions and cultures that the feet are probably the least attractive parts of the anatomy. Hence, the idea of a priest In Persona Christi washing my feet makes me feel more than a little uncomfortable, and I daresay the apostles weren't exactly keen on the idea when Our Lord performed this task. Let us follow the advice of Gueranger:
"the feet are those earthly attachments, which so often lead us to the brink of sin. Let us watch over our senses, and the affections of our hearts. Let us wash away these stains by a sincere confession, by penance, by sorrow, and by humility; that thus we may worthily receive the adorable Sacrament, and derive from it the fulness of its power and grace."
