Divine Liturgy of the Last Supper is held on the morning of Great and Holy Thursday, combining Vespers with the Liturgy of Saint Basil the Great. There is a custom among some churches to place a simple white linen cloth over the Holy Table (altar) for this Liturgy, reminiscent of the Last Supper. In cathedrals and monasteries it is customary for the bishop or hegumen (abbot) to celebrate the Washing of Feet. When it is necessary for an autocephalous church to consecrate more chrysm the primate of that church will consecrate it at this Liturgy.
