On the Sunday before the Feast of Great and Holy Pascha and at the beginning of Holy Week, the Orthodox Church celebrates one of its most joyous feasts of the year. Palm Sunday is the commemoration of the Entrance of our Lord into Jerusalem following His glorious miracle of raising Lazarus from the dead.
Beginning on the evening of Palm Sunday and continuing through the evening of Holy Tuesday, the Orthodox Church observes a special service known as the Service of the Bridegroom.
On Great and Holy Friday the Orthodox Church commemorates the death of Christ on the Cross. This is the culmination of the observance of His Passion by which our Lord suffered and died for our sins. This commemoration begins on Thursday evening with the Matins of Holy Friday and concludes with a Vespers on Friday afternoon that observes the unnailing of Christ from the Cross and the placement of His body in the tomb.
