Holy Thursday commemorates the Last Supper when Christ instituted the priesthood. In some churches the feet of 12 men or alter boys are symbolically washed by the priest, just as Christ did his apostles before the supper. The church bells that had resounded from Palm Sunday onwards fall silent. Rattles and clappers take their place.
In the past fires were lit at crossroads so that wayfarers and poor people could warm themselves. Meals were also placed at these spots so that these people could nourish themselves. On the morning of Holy Thursday, the vestments are changed on the miraculous icon in the chapel of the Pauline monastery at Jasna Gora in Czestochowa. This is one of the most important sites of the religious cult of the Poles, and has been venerated as a national shrine since 14 th century.
