The week preceding Easter. The commemoration of Christ’s sufferings determines many of its functions: the reading of the Passion on Palm Sunday, Tuesday, Wednesday, and Friday, respectively according to Matthew, Mark, Luke, and John; the silence of the bells from Holy Thursday to Holy Saturday; the stripping of the altars on Thursday; the unveiling and adoration of the Cross on Good Friday; Tenebrae on the last three days. The termination of the catechumenate with Baptism on Saturday determined other functions: the blessing of the Holy Oils on Thursday; the prophecies and blessing of the baptismal font on Saturday. The function of Holy Saturday originally took place during the following night. In great part the ceremonies of Holy Week originated in Jerusalem.
